Abstract
An example embodiment provides a sensor system including a tag unit and a readout unit. The tag unit includes a first sensor having a stretchable antenna and a stretchable resistor. The tag unit may be configured to create a sensing signal corresponding to a degree of stretching of the stretchable resistor, transmit the sensing signal to the readout unit through the stretchable antenna, and operate in a first region corresponding to a first frequency. The readout unit may be inductively coupled to the tag unit and may be configured to receive and read out the sensing signal, and operate in a second region corresponding to a second frequency. The first frequency may range 30 MHz to 50 MHz, and the second frequency may be different from the first frequency.
