A WIRELESS, HIGH-RESOLUTION, AND SMARTWATCH-COMPATIBLE WEARABLE DATA READOUT SYSTEM FOR LOW-VOLTAGE TRANSISTOR CHARACTERIZATION

Title:

A WIRELESS, HIGH-RESOLUTION, AND SMARTWATCH-COMPATIBLE WEARABLE DATA READOUT SYSTEM FOR LOW-VOLTAGE TRANSISTOR CHARACTERIZATION

Document Type and Number:

WIPO Patent Application WO/2023/098709

Kind Code:

A1

Abstract:

An electronic reader for electro-chemical transistors (OECT) includes a potential output control module that controls the Vd, Vs, and Vg for the OECT under test, a high accuracy current monitor module which contains a transimpedance amplifier (TIA) used to control the output voltage and convert the input channel current Ids into a voltage value. A microcontroller (MCU) that controls the working sequences of the TIA so as to realize the specific characterization mode and enable an adjustable output voltage range. The MCU further controls a programmable sampling rate of up to 200k samples per second (SPS) with low noise by down-sampling the base rate, convolution processing it and interpolating it back to ah high frequency, but without the noise. The device is small enough to be worn by a user and its output is sent to a mobile device for reading.
