Enhanced Percolation Effect in Sub-100 Nm Nanograting Structure for High-Performance Bending Insensitive Flexible Pressure Sensor (Adv. Electron. Mater. 10/2025)

Abstract

Flexible Pressure Sensors

In article number 2400980, Jae-Young Yoo, Jun-Bo Yoon, and co-workers develop a high-performance flexible pressure sensor using a sub-100 nm valley nanograting structure to enhance the percolation effect while maintaining bending insensitivity. This sensor reliably detects subtle pressures, such as arterial pulses, even on curved surfaces, making it ideal for wearable healthcare and tactile sensing applications. This cover illustrates the sensor's ability to maintain bending insensitivity while sensitively detecting arterial pulses, suggesting its potential for future applications in plantar pressure mapping.
