In article number 2006186, Wei Lin Leong and co‐workers present the first report on pressure sensing modalities using organic electrochemical transistors (OECTs). A new pressure sensing mechanism through contact modulated induced doping is revealed. These devices exhibit high pressure sensitivity (≈10000 kPa −1 ) and excellent stability at an operation voltage of less than 1V. Flexible sensors arrays demonstrate the ability to map pressure distribution and track motion. The findings will further advance and broaden the applications of OECTs such as in soft robotics, health monitoring, and human‐machine interfaces.
