Title:
SYSTEMS AND METHODS FOR ENVIRONMENT SENSING
Document Type and Number:
WIPO Patent Application WO/2018/067316
Kind Code:
A3
Abstract:
Systems and methods are provided for environment sensing. The system includes a sensor having a sensing material and at least one pair of electrodes in contact with the sensing material, the sensing material configured to be in contact with an ambient environment. The system includes a controller circuit electrically coupled to the at least one pair of electrodes. The controller circuit is configured to generate a stimulation waveform for application to the sensing material of the sensor via the at least one pair of electrodes. The controller circuit is configured to receive an electrical signal from the at least one pair of electrodes representative of an impedance response of the sensing material, and analyze the impedance response of the sensing material at frequencies that provide a linear response of the sensing material to an analyte of interest and at least partially reject effects of interferences.
