Flexible pressure sensors have garnered significant attention for their potential in flexible electronics and interactive devices. However, such sensing devices typically rely on external bulky equipment data visualization, which prevents from becoming smaller more portable.

This work successfully demonstrates visualization human finger bending recognition weight measurement. Moreover, this will enhance the visualizable identification capabilities robotic hands prosthetics, thereby offering users intuitive real-time experience.

A novel hollow capacitive wind pressure sensor is for the first time proposed. The sensing element of proposed uses a non-parallel plate variable capacitor, whose movable electrode transversely uniformly loaded annular conductive membrane with fixed outer edge and rigid inner (acting as sensitive sensor). Due to unique configuration sensor, it can be used alone detect exerted by fast-moving air in atmosphere or gas, etc., pipes, but also pairs measure flow rate pipes. analytical solution large deflection elastic behavior derived using new set governing equations. effectiveness analyzed. equations are compared previous ones show differences between them. superiority over existing An example given demonstrate numerical design calibration effect changing parameters on important capacitance–pressure (C–q) relationship investigated comprehensively. Finally, an experimental verification carried out.

Flexible piezoresistive pressure sensors have great potential in wearable electronics due to their simple structure, low cost, and ease of fabrication. Porous polymer materials, with highly deformable internal pores, effectively expand the sensing range. However, a single-sized pore structure struggles achieve both high sensitivity broad range simultaneously. In this study, PDMS-based flexible sensor bilayer porous (BLPS) was successfully fabricated using clamping compression sacrificial template method spherical sucrose cores. The resulting exhibits uniform sizes, thereby improving performance consistency. Furthermore, since different sizes thicknesses correspond varying Young’s moduli, study achieves tunable across wide by adjusting thickness ratio (maximum 0.063 kPa−1 0–23.6 kPa range, response 0–654 kPa). also demonstrates fast time (128 ms) excellent fatigue stability (>10,000 cycles). Additionally, holds application for facial expression monitoring, joint motion detection, distribution matrices, Morse code communication.
