Abstract
A flexible sensing system includes: a flexible tag device including a first antenna, first sensor and second sensors, first modulation transistor and second modulation transistors connected to both ends of the first antenna, first ring oscillator that drives the first modulation transistor together with the first sensor, and a second ring oscillator that drives the second modulation transistor together with the second sensor; and a reader device that is flexible and includes a second antenna that is inductively coupled with the first antenna, extracts an output signal of the tag device for each frequency bandwidth, and corrects an output signal change of the tag device according to a coupling change between the first antenna and the second antenna.
