Abstract：
Flexible pressure sensors with a broad range and high sensitivity are greatly desired yet challenging to build. Herein, we have successfully fabricated a pressure-temperature dual sensor via an ionic assisted charge enhancement strategy. Benefiting from the immobilization effect for [EMIM+] [TFSI-] ion pairs and charge transfer between ionic liquid (IL) and HFMO (H10Fe3Mo21O51), the formed IL-HFMO-TPU pressure sensor shows a high sensitivity of 25.35 kPa-1 and broad sensing range (∼10 MPa), respectively. Furthermore, the sensor device exhibits high durability and stability (5000 cycles@1 MPa). The IL-HFMO-TPU sensor also shows the merit of good temperature sensing properties. Attributed to these superior properties, the proposed sensor device could detect pressure in an ultrawide sensing range (from Pa to MPa), including breathe and biophysical signal monitoring etc. The proposed ionic assisted enhancement approach is a generic strategy for constructing high performance flexible pressure-temperature dual sensor.
摘要：
非常需要具有宽范围和高灵敏度的柔性压力传感器,但构建起来具有挑战性。在这里，我们已经成功地制造了一个压力温度双传感器通过离子辅助电荷增强策略。受益于[EMIM+][TFSI-]离子对的固定作用和离子液体(IL)与HFMO(H10Fe3Mo21O51)之间的电荷转移,所形成的IL-HFMO-TPU压力传感器具有25.35kPa-1的高灵敏度和宽传感范围(~10MPa)，分别。此外，传感器装置具有高耐久性和稳定性（5000次循环@1MPa）。IL-HFMO-TPU传感器还显示出良好的温度感测特性的优点。归因于这些优越的特性，所提出的传感器设备可以检测超宽传感范围(从Pa到MPa)内的压力，包括呼吸和生物物理信号监测等。所提出的离子辅助增强方法是构建高性能柔性压力-温度双传感器的通用策略。
