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.
