Significant efforts have been devoted to enhancing the sensitivity and working range of flexible pressure sensors to improve the precise measurement of subtle variations in pressure over a wide detection spectrum. However, achieving sensitivities exceeding 1000 kPa⁻¹ while maintaining a pressure working range over 100 kPa is still challenging because of the limited intrinsic properties of soft matrix materials. Here, we report a magnetic field-induced porous elastomer with micropillar arrays (MPAs) as sensing materials and a well-patterned nickel fabric as an electrode. The developed sensor exhibits an ultrahigh sensitivity of 10,268 kPa⁻¹ (0.6–170 kPa) with a minimum detection pressure of 0.25 Pa and a fast response time of 3 ms because of the unique structure of the MPAs and the textured morphology of the electrode. The porous elastomer provides an extended working range of up to 500 kPa with long-time durability. The sophisticated sensor system coupled with an integrated wireless recharging system comprising a flexible supercapacitor and inductive coils for transmission achieves excellent performance. Thus, a diverse range of practical applications requiring a low-to-high pressure range sensing can be developed. Our strategy, which combines a microstructured high-performance sensor device with a wireless recharging system, provides a basis for creating next-generation flexible electronics.

已投入大量努力来提高柔性压力传感器的灵敏度和工作范围，以改进在宽检测范围内对压力细微变化的精确测量。然而，由于软基质材料的固有特性有限，在保持超过 100 kPa 的压力工作范围的同时实现超过 1000 kPa ^{-1 的}灵敏度仍然具有挑战性。在这里，我们报告了一种磁场诱导的多孔弹性体，其微柱阵列 (MPA) 作为传感材料，图案良好的镍织物作为电极。开发的传感器具有 10,268 kPa ^-1的超高灵敏度(0.6–170 kPa) 具有 0.25 Pa 的最小检测压力和 3 ms 的快速响应时间，因为 MPA 的独特结构和电极的纹理形态。多孔弹性体提供高达 500 kPa 的扩展工作范围和长期耐用性。复杂的传感器系统与集成的无线充电系统相结合，该系统包括一个灵活的超级电容器和用于传输的感应线圈，实现了卓越的性能。因此，可以开发需要低到高压范围感测的各种实际应用。我们的策略将微结构高性能传感器设备与无线充电系统相结合，为创建下一代柔性电子产品提供了基础。
