Ultra‐Rapidly Responsive Electret‐Based Flexible Pressure Sensor via Functional Polymeric Nanoparticle Synthesis (Adv. Funct. Mater. 51/2024)

Electret‐Based Flexible Pressure Sensors Flexible electrets can be used to construct eco‐friendly devices that utilize dielectric materials to measure physical parameters without requiring any power supply. In article number 2402064, Seigou Kawaguchi, Tomohito Sekine, and co‐workers synthesize electret‐type particles with self‐power‐generating properties and apply those to flexible pressure sensors. Notably, an ultrafast response is achieved despite the sensor device being flexible and fabricated using a solution process.
