This application claims priority under 35 U.S.C. §119 to Taiwan Patent Application No. 097214062, filed on Aug. 6, 2008, in the Taiwan Intellectual Property Office, the entire contents of which are hereby incorporated by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a sensing device, in particular to an elastic cloth device with a function of physiological detection for detecting physiological signals.

2. Description of Related Art

With the improvement of people's living standards, people pay more and more attention to their health. People usually use all kinds of physiological measurement apparatus to detect their current physiological parameters at all times so as to remain informed and thereby adjust their health conditions properly.

However, physiological detection has many detection types, such as ECG (electrocardiogram), body temperatures, brain waves, pulses, and so on. A conventional physiological detection device, for example, a glove-typed physiological measurement device disclosed in Taiwan Patent Certificate No. M301046 (Application No. 95208968), includes a glove body, a physiological measurer, and a physiological detector. The glove body is worn on a user's hand, and electrical connection bases are respectively disposed on the back of the hand and the fingers. Electric circuitries electrically couple between the electrical connection bases respectively. The physiological measurer has electrical connectors engaging with the electrical connecting bases on the back of the hand and the physiological detector also has electrical connectors engaging with the electrical connecting bases on the fingers, so that the physiological detector can contact the user's fingers and obtain pulse signals, and then transmit the pulse signals to the physiological measurer to show the measured value to the user.

However, the glove-typed physiological measurement device still has some shortcomings. For example, except for hands, it cannot be used on other body parts such as wrists, chests, and so on, so the glove-typed physiological measurement device has a narrow usage range. Furthermore, the physiological detector has a small contact area with skins, so that the obtained signals according to the physiological strain reactions always have limited strength and the noise is too high, therefore accurate physiological signals are difficult to obtain

Hence, the inventors of the present invention believe that the shortcomings described above are able to be improved and finally suggest the present invention which is of a reasonable design and is an effective improvement based on extensive research and thought.
