FABRIC WITH STRETCHABLE SENSORS FOR SHAPE MEASUREMENT

FIELD OF ART

This application relates generally to size measurement and more particularly to fabric with stretchable sensors for shape measurement.

BACKGROUND

The accurate measurement of a given three-dimensional shape has many applications in the fields of garments, clothing, protection, industrial automation, scientific research, and recycling/reclamation, among others. The measured shapes can be objects of interest, manufactured parts, etc. The shape measurement can be used for object differentiation. In shape measurement applications that involve the human body, there are further applications in the healthcare and fashion industries. While the former is used to obtain data necessary to obtain medical information and to design medical treatments, the latter is used to determine the proper fit of clothing, accessories, and equipment. The proper fit of clothing and equipment is essential for comfort, safety, and appearance, particularly for people who are in physically strenuous professions such as emergency response, law enforcement, defense, athletics, and the like. Footwear in particular is an item of clothing in which sizing is of utmost importance in order to reduce or eliminate the risks of fatigue, injury, and so on.

Since a person's clothing and shoe sizes can change over time, body measurements may need to be periodically reassessed so that clothing and footwear can be properly updated to accommodate for size changes in order to promote comfort and functionality. As people grow and age, their physical size changes. The period of most rapid change, of course, occurs in children, where their growth rate may be classified into two distinct stages: before puberty and during puberty. In the first stage, a prepubescent child tends to grow at a steady rate of about two to three inches per year between the approximate ages of two and ten until the start of puberty, when a rapid growth spurt signals the development of a child into their full adult size. This second pubescent stage generally occurs between the ages of nine and fifteen. Even after a child has developed into an adult, muscle mass, weight, and physical shape continue to change throughout adulthood for reasons such as pregnancy, diet, weight gain or loss, strength training, injury, illness, and so on. In addition, people may have daily fluctuations in size due to diet, water retention, stress, altitude, and other factors.

Properly sized clothing and footwear is important for appearance, safety, and comfort. For specialized occupations such as firefighting, athletics, and construction work, properly fitting clothing and footwear is essential in order to successfully perform the needed tasks. As people's physical measurements change with age, shoe and clothing size is often reevaluated to ensure a proper fit and thus provide functionality and comfort in a variety of settings.

SUMMARY

Properly sized garments of all descriptions, such as clothing and footwear, as well as equipment worn on the body, are critical to personal comfort, safety, and appearance. While a loose-fitting jacket may be considered fashionable, an ill-fitting respirator or mask can be life threatening. The sizes and shapes of bodies tend to change over time as people grow and age. It is therefore desirable to take body measurements from time to time to ensure that clothing, footwear, and equipment continue to fit properly. Disclosed embodiments provide a fabric garment for measurement. The garment, which includes a fabric and a stretchable electronic sensor module, can be formed into articles of clothing, such as socks, pants, shirts, hats, and gloves. The sensor module has a property of changing electrical properties, such as resistance and/or capacitance, when stretched. By calculating the change in electrical properties when a wearer is wearing such a garment, physical dimensions can be ascertained. The physical dimensions can include size, shape, circumference, diameter, volume, surface area, etc., and can then be converted to a higher level size such as a shoe size, blouse size, or the like.

Disclosed embodiments provide shape measurements and body measurements. A garment has a sensor module attached. The garment encompasses a body portion. The sensor module is stretchable and provides electrical data. The electrical data is based on the amount that the sensor module is stretched. The electrical data from the sensor module is collected. The collected electrical data is analyzed to determine a measurement for the body portion. A size for the body portion is calculated, based on the measurement. A second sensor module can also be attached to the garment. Electrical data from the second sensor is also collected and analyzed. A size for the body portion is further calculated based on the electrical data from the sensor module and the second sensor module. The sensor module and the second sensor module transmit data to a computing device using distinct, wireless transmitters. A processor-implemented method for body measurement is disclosed comprising: attaching a sensor module to a garment, wherein the sensor module is stretchable and provides electrical data based on an amount that the sensor module is stretched, and wherein the garment encompasses a body portion; collecting the electrical data from the sensor module based on the amount that the sensor module stretched; analyzing the electrical data that was collected to determine a measurement for the amount that the sensor module stretched; and calculating a size for the body portion based on the measurement that was determined.

In embodiments, also disclosed is attaching a second sensor module to the garment; collecting a second electrical data from the second sensor module, wherein the second electrical data is collected based on stretching of the second sensor module; analyzing the second electrical data that was collected to determine a second measurement for the amount that the second sensor module stretched; and further calculating the size for the body portion based on the measurement and the second measurement that were determined. In embodiments, disclosed is a computer program product embodied in a non-transitory computer readable medium for body measurement, the computer program product comprising code which causes one or more processors to perform operations of: attaching a sensor module to a garment, wherein the sensor module is stretchable and provides electrical data based on an amount that the sensor module is stretched, and wherein the garment encompasses a body portion; collecting the electrical data from the sensor module based on the amount that the sensor module stretched; analyzing the electrical data that was collected to determine a measurement for the amount that the sensor module stretched; and calculating a size for the body portion based on the measurement that was determined.

DETAILED DESCRIPTION

Disclosed embodiments provide a way to measure the shape and size of an object using a sensor module attached to a garment, particularly the measurement of human body portions such as legs, arms, head, feet, and the like. The measurements can be acquired by simply wearing a garment comprised of one or more sensor modules. Changes in electrical properties such as resistance and/or capacitance and/or inductance are measured. These electrical properties are converted to distance measurements. The measurements are collected by a processor. The processor can analyze the data to determine sizing information, or the measurement data can be transmitted elsewhere to a server or other device so that the sizing information can be converted to a higher level size, such as a dress size or other common system of apparel measurement. Alternatively, the sizing information can be converted to a clothing pattern to efficiently enable fabrication of customized clothing based on size.

Another application of the disclosed embodiments is the measuring of size over time. The sizing information can be acquired from a local processor and can then be uploaded via a near field communication system, such as Bluetooth™ to a mobile phone, for data collection and analysis. Such size and shape data collection can have applications in the field of physical health and wellness, as the monitoring of size over time can provide useful medical information. For example, an undergarment equipped with a measuring garment integrated into the waistband can provide daily updates on waist size. The garment can then transmit results to a user's mobile phone. The mobile phone can execute a program (app) to track waist size and alert the user if the waist size exceeds a predetermined level, which can, in turn, alert the user to cut back on caloric intake. Another application of periodic measurement can pertain to athletes. In such an embodiment, bodybuilders, weight lifters, runners, or other athletes can easily track size increases and decreases as they train.

In other embodiments, the quick assessment of size in an electronic form allows for unprecedented capabilities in custom-manufactured clothing, safety devices, personal equipment such as earphones, etc. For example, a user can use a measuring garment to quickly obtain detailed foot measurements and transmit the measurements to an online shoe store. Customized shoes can be manufactured to the specifications of the measurements provided by the user. Alternatively, the shoe store can search a product database to select existing footwear that most closely matches the detailed size information provided by the measuring garment. These, among others, are just a few applications for the use of measuring clothing and footwear size using a sensor module attached to a garment. In numerous cases, sizes are critical to correct fitting of garments or devices used for protection or safety. In such uses, precise sizing is essential such as in the case of astronauts, scuba divers, soldiers, airmen, pilots, marines, and so on. People who wear uniforms or safety devices can benefit from proper and easy sizing evaluation. Further, correct sizing can be quite helpful for people such as pregnant mothers, plus size people, big and tall individuals, others who are larger than average or smaller than average, people whose size changes rapidly, and the like. In addition, business attire, athletic apparel, and other garments can be optimally fit for best usage and appearance.

The measurements that can be obtained from the garment can be based on a circumference of a portion of a body. Such a measurement can include the circumference of an arm or a leg, and can be used to determine a size of the limb, a change in size (size delta) of the limb, and so on. The size delta for the limb can be used as in a medical application to track edema. The measurements can include a size such as a length, a width, a thickness, and so on. The measurements can include a distance between landmarks of a body or portion of a body, such as the distance between a shoulder and an elbow, and elbow and a wrist, a hip and a knee, a knee and an ankle, etc. The measurements for sizing can be used for preoperative evaluations, postoperative tracking, sizing of medical appliances, etc.

Other measurements can also be obtained from the garment. The other measurements can include measuring linear displacement or elongation of a portion of a body. The elongation that can be measured and/or inferred can be based on a changing angle of the portion of the body. The portion of the body can include an elbow, a knee, an ankle, a neck, a shoulder, a hip, etc. The measuring of an angle can be used for such applications as postoperative physical therapy to determine progress relating to range of motion of the portion of the body. The measuring of the size and the angle relating to range of motion of the portion of the body can be used to evaluate progress toward postoperative physical therapy goals, to identify excess swelling, to fit a medical device such as a brace or cast, and so on.

The electrical data that is collected can be analyzed to determine a measurement for the amount of stretch of the sensor module. The analyzing can be performed by the sensor module or by an external computing device. A size is calculated for the body portion based on the measurement that was determined. The calculation can be performed by the sensor module or by an external computing device.

The electronic component can include a polymer. The stretchable electronic component can be stretchable in a single direction, denoted in the figure by displacement.

The structure of the electrodes 1010 and 1012 separated by a dielectric 1020 can be approximated by a parallel plate capacitor. The equation that describes a parallel plate capacitor is:

$C = \frac{ɛ A}{d}$

where C equals capacitance, epsilon-E equals permittivity, A equals length times width (area), and d equals separation, the latter denoted in 1000 by thickness. Assuming that the separation d between the electrodes remains constant as the electrode and dielectric structure is stretched, then length increases causing capacitance to also increase. By calculating the change in capacitance as a result of stretching the electronic component, shape measurement can be performed. In embodiments, as the material is stretched the dielectric can thin and/or the plate area becomes larger resulting in an increased capacitance. The increase in capacitance can be equated to an amount of stretch and thereby used for size measurement.

Resistance values that can result from the stretching of the stretchable electronic components 1120, 1122, etc. can be collected from the segments. A human body portion typically has a complex shape of varying size throughout. For example, a leg is typically widest at the midpoint of the quadriceps and then narrows at the knee, widens again at the calf, and comes to its narrowest point at the ankle. The use of multiple segments allows for measurement of such complex shapes. The resistive and piezoelectric sensors of 1100 that can measure resistance can further include a processing module 1110.
