Flexible and wearable devices are important parts toward the realization of artificial intelligence and have an irreplaceable advantage over traditional rigid sensors. In this work, a film with double surface structure is prepared by using sandpaper and the leather with a rhombic structure as a mold, thereby obtaining a sandwich structure resistive type pressure sensor, which has high sensitivity (77.78 kPa⁻¹, 24 Pa minimum detection) and wide detection range (0.024–230 kPa). The sensors have fast response time (30 ms) and high reliability over 5000 repetitive cycles. The humidity sensor is printed on the top layer of the sensor by using screen printing and inkjet printing technique, and the sandwich structure humidity and pressure sensor is obtained. The humidity sensors show the sensitivities of 0.137/%, 1.57/%, and 11.145/% in the relative humidity range from 25 to 55%, 55 to 70%, and 70 to 80%, respectively. Such sensors not only have excellent capabilities in pressure and humidity detection, but also avoid the complex process of multiple single‐function devices stacked on each other. The applications of sensors in monitoring artery pulse waves, detecting spatial pressure distribution, and sweat is demonstrated.

通过具有三明治结构的成型和喷墨印刷工艺实现的灵活的湿度和压力传感器

柔性和可穿戴设备是实现人工智能的重要组成部分，与传统的刚性传感器相比具有不可替代的优势。在这项工作中，通过使用砂纸和具有菱形结构的皮革作为模具来制备具有双重表面结构的膜，从而获得具有高灵敏度（77.78 kPa ^-1的夹心结构电阻型压力传感器）。，最小检测值为24 Pa）和宽检测范围（0.024–230 kPa）。传感器具有快速响应时间（30毫秒）和超过5000个重复周期的高可靠性。通过丝网印刷和喷墨印刷技术将湿度传感器印刷在传感器的顶层，得到三明治结构的湿度压力传感器。湿度传感器在25至55％，55至70％和70至80％的相对湿度范围内分别显示出0.137 /％，1.57 /％和11.145 /％的灵敏度。这种传感器不仅具有出色的压力和湿度检测能力，而且还避免了将多个单功能设备相互堆叠的复杂过程。演示了传感器在监测动脉脉搏波，检测空间压力分布和汗液中的应用。
