Abstract

High-performance flexible pressure sensors are crucial for achieving precise tactile sensing and play an indispensable role in human motion detection and human-machine interaction. In this study, a new low-cost flexible capacitive pressure sensor (CPS) is designed using the bionic microstructure of a grasshopper leg with polydimethylsiloxane (PDMS) as the dielectric layer. Through finite element simulation and structural optimization, the CPS can achieve high sensitivity (0.925 kPa

$^{-{1}}$

), a wide pressure sensing range (5 Pa–388 kPa), fast response time (30 ms), excellent consistency across sensor batches, and outstanding stability. Additionally, the study demonstrates the CPS’s capabilities in intelligent robots manipulator operations, human hand grasping objects with tactile feedback, human motion posture detection, and information transfer of Morse code in practical applications. Given the outstanding performance of the CPS, it is poised to be a preferred choice for future wearable devices and human-machine interaction.

期刊介绍： IEEE Transactions on Electron Devices publishes original and significant contributions relating to the theory, modeling, design, performance and reliability of electron and ion integrated circuit devices and interconnects, involving insulators, metals, organic materials, micro-plasmas, semiconductors, quantum-effect structures, vacuum devices, and emerging materials with applications in bioelectronics, biomedical electronics, computation, communications, displays, microelectromechanics, imaging, micro-actuators, nanoelectronics, optoelectronics, photovoltaics, power ICs and micro-sensors. Tutorial and review papers on these subjects are also published and occasional special issues appear to present a collection of papers which treat particular areas in more depth and breadth.
