Title:
STATE DETECTION SYSTEM, DETECTION DEVICE, STATE DETECTION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/018853
Kind Code:
A1
Abstract:
This state detection system comprises a detection device for detecting the state of a specimen, and an information processing terminal having an antenna and supplying power wirelessly to the detection device, the detection device having: a detection unit formed on the specimen and constituted by a plurality of capacitors formed by sandwiching a dielectric material between a pair of conductors; an IC chip connected to the detection unit, the IC chip having a charging/discharging circuit that applies a voltage to or stops applying a voltage to the plurality of capacitors, an AD conversion circuit that converts analog signals from the plurality of capacitors into digital signals, and a memory in which information specific to the specimen is stored; and a wireless communication antenna that is connected to the IC chip and that receives the wireless power supply from the information processing terminal. The detection device detects the state of the specimen on the basis of the digital signal relating to the voltage value of the detection unit measured at a predetermined timing during discharging of the plurality of capacitors.
