Title:
PRINTED MULTI-ANALYTE DISPOSABLE ELECTRONIC SENSOR STRIP
Document Type and Number:
WIPO Patent Application WO/2024/044733
Kind Code:
A3
Abstract:
Disclosed are systems and methods for measuring data from an environment. The system may be an environmental sensor that includes a substrate and four layers. The first layer may include source and drain electrodes. The second layer may include at least three electrodes including a working electrode that is a gate material comprising a blend of carbon ink and an indicator and a Ag/AgCl reference electrode. The third layer may include a semiconducting channel formed of PEDOT:PSS. The fourth layer may include a dielectric ink. The environment sensor may be used to determine an electrical conductivity, calculate a temperature, and measure a pH of the environment.
