Flexible sensor with high precision and sensitivity in detecting pressure and temperature is highly desired. Herein, we design a flexible iontronic sensor by sandwiching a sandpaper-like ionogel layer between two silver nanowires-loaded polymeric nanofiber films. The obtained sensor can serve as a flexible pressure sensor with high precision (1.18 Pa), high sensitivity (106.01 kPa⁻¹), wide measuring range (0–77 kPa), fast response/recovery time (16 ms/25 ms), and good stability over 2000 cycles because of the continuous change in the contract between electrode and dielectric layer under pressure and the formation of electric double layer between them. Owing to these excellent merits in pressure sense, the as-prepared sensor can real-time monitor tiny pressure caused by pulse, facial movements, and swallowing. More interestingly, this sensor can also serve as a temperature sensor, which has outstanding integrated performance of high precision of 0.02 °C, high sensitivity of 28.1% °C⁻¹ (20–40 °C), wide operating window from −40 °C to 80 °C, superb repeatability and reliability, attributing to the monotonous relationship between the dielectric constant of TPU/IL ionogel and temperature. The designed sensor has bright prospects in flexible electronics and electronic skins for monitoring human health and human motion.

非常需要在检测压力和温度方面具有高精度和灵敏度的柔性传感器。在此，我们通过在两个载有银纳米线的聚合物纳米纤维薄膜之间夹入一层类似砂纸的离子凝胶层来设计一种柔性离子电子传感器。所得传感器可作为柔性压力传感器，具有高精度（1.18 Pa）、高灵敏度（106.01 kPa ⁻¹), 测量范围宽 (0–77 kPa), 响应/恢复时间快 (16 ms/25 ms), 由于电极与介电层在压力下的接触不断变化并形成 2000 次循环, 稳定性好它们之间的双电层。由于在压力感知方面的这些优异优点，所制备的传感器可以实时监测由脉搏、面部运动和吞咽引起的微小压力。更有趣的是，该传感器还可以作为温度传感器使用，具有0.02°C的高精度、28.1%°C的高灵敏度的出色综合性能^-1(20–40 °C)，-40 °C 至 80 °C 的宽操作窗口，出色的可重复性和可靠性，归因于 TPU/IL 离子凝胶的介电常数与温度之间的单调关系。所设计的传感器在用于监测人体健康和人体运动的柔性电子和电子皮肤方面具有广阔的前景。
