Simulation of somatosensory systems in human skin with electronic devices has broad applications in the development of intelligent robots and wearable electronic devices. Here, we give an account of a new biomimetic flexible dual-mode pressure sensor, which is based on the first developed sea dandelion-like conductive metal–organic framework (cZIF-67@Cu-CAT) and the self-synthesized mechanically luminescent zinc sulfide nanoparticles and cleverly combines the microdome structure of the lotus leaf. According to finite element simulation analysis (FEA), the deformation behavior and pressure distribution of the contact interface with dandelion-like nanostructures cause the contact area of the sensor to increase rapidly and steadily with the load. It is for this reason that the piezoresistive pressure sensor has a high sensitivity of 71.74 kPa⁻¹ over a wide range of 0.5 to 80 kPa. More importantly, it can roughly perceive stress changes in the external environment through mechanoluminescence materials without a power supply. The ultra-thin flexible pressure sensor is suitable for sensitive monitoring of small vibrations, including wrist pulse and joint motion. Combined with Bluetooth data transmission, it is not difficult to see that the high-sensitivity ultra-thin sensor designed in this study has broad potential in the applications of bio-wearable electronics and will play an immeasurable role in various sports training and joint protection in the future.

一种由 ZIF-67 和导电金属有机骨架复合材料制备的具有多响应能力的超薄柔性可穿戴传感器，用于健康信号监测

用电子设备模拟人体皮肤的体感系统在智能机器人和可穿戴电子设备的开发中有着广泛的应用。在这里，我们介绍了一种新型仿生柔性双模压力传感器，它基于第一个开发的海蒲公英状导电金属有机框架（cZIF-67@Cu-CAT）和自合成的机械发光锌硫化物纳米颗粒与荷叶的微圆顶结构巧妙结合。根据有限元模拟分析（FEA），具有蒲公英状纳米结构的接触界面的变形行为和压力分布导致传感器的接触面积随负载快速而稳定地增加。正是由于这个原因，压阻式压力传感器具有71.74 kPa的高灵敏度^-1在 0.5 至 80 kPa 的宽范围内。更重要的是，它可以在没有电源的情况下，通过机械发光材料粗略感知外界环境的应力变化。超薄柔性压力传感器适用于对微小振动的灵敏监测，包括手腕脉搏和关节运动。结合蓝牙数据传输，不难看出，本研究设计的高灵敏度超薄传感器在生物可穿戴电子应用中具有广阔的应用潜力，将在各种运动训练和关节保护等方面发挥不可估量的作用。未来。
