Abstract:
According to an embodiment of the present invention, a structure for a strain gauge device is provided. The structure comprises a layer of strain gauge material and one or more contact pads positioned directly on the layer of strain gauge material. The structure further comprises a multiplexer, measuring device, amplifier, analog to digital converter, microcontroller, and wireless adapter. According to the structure, the multiplexer selects a given contact pad pair of the one or more contact pad pairs, the measuring device measures signal generated by the layer of strain gauge material between the given contact pad pair, the amplifier amplifies the measured signal, the analog to digital converter converts the amplified analog signal to a digital signal, the microcontroller processes the digital signal, and the wireless adapter transmits the processed digital signal. In addition, the structure may further comprise a battery to provide energy to the structure.
