• The laser-engraved method was introduced to fabricate the electrode for the sensor.

• The sensor showed a wide linear working range, superior sensitivity, and fast response time and also exhibited excellent viability in a wet situation.

• Wireless integrated network sensors successfully monitored the health states.

Developing flexible sensors with high working performance holds intense interest for diverse applications in leveraging the Internet-of-things (IoT) infrastructures. For flexible piezoresistive sensors, traditionally most efforts are focused on tailoring the sensing materials to enhance the contact resistance variation for improving the sensitivity and working range, and it, however, remains challenging to simultaneously achieve flexible sensor with a linear working range over a high-pressure region (> 100 kPa) and keep a reliable sensitivity. Herein, we devised a laser-engraved silver-coated fabric as “soft” sensor electrode material to markedly advance the flexible sensor’s linear working range to a level of 800 kPa with a high sensitivity of 6.4 kPa⁻¹ yet a fast response time of only 4 ms as well as long-time durability, which was rarely reported before. The integrated sensor successfully routed the wireless signal of pulse rate to the portable smartphone, further demonstrating its potential as a reliable electronic. Along with the rationally building the electrode instead of merely focusing on sensing materials capable of significantly improving the sensor’s performance, we expect that this design concept and sensor system could potentially pave the way for developing more advanced wearable electronics in the future.

开发具有高工作性能的柔性传感器对利用物联网（IoT）基础架构的各种应用引起了浓厚的兴趣。对于柔性压阻传感器，传统上，大多数工作都集中在定制感测材料上，以增强接触电阻的变化，从而提高灵敏度和工作范围，然而，要同时获得在高量程下线性工作范围的柔性传感器仍然具有挑战性。压力范围（> 100 kPa）并保持可靠的灵敏度。在此，我们设计了一种激光雕刻的镀银织物作为“软”传感器电极材料，以将柔性传感器的线性工作范围显着提高到800 kPa的水平，并具有6.4 kPa ^-1的高灵敏度。响应时间仅为4毫秒，并且具有长期耐用性，这在以前很少见。集成传感器成功将脉搏率的无线信号路由到便携式智能手机，进一步证明了其作为可靠电子设备的潜力。我们期望合理地构建电极，而不仅仅是专注于能够显着改善传感器性能的传感材料，我们希望这种设计概念和传感器系统有可能为将来开发更高级的可穿戴电子设备铺平道路。
