A mechanoreceptor is a sensor in the human body used to detect signals from the environment, and it induces bodily responses via the brain. We designed a transparent mechanoreceptor using a metal-oxide heterojunction to develop the skin-adopted concept. A highly transparent device (>60%) on PET substrate is obtained using wide bandgap oxide heterostructure. These layers spontaneously provide photovoltaic power (15 μW) to operate the mechanoreceptor without an external power supply system. We show that flexible device provides fast photo response of order of µs, offers solutions ultrafast mechanoreceptor for self-powered skin application. The mechanoreceptor can also operate well above 200 Hz for future ultrafast e-skin. In addition, the photovoltaic mechanoreceptor can be developed on a flexible substrate that is compatible with skin applications such as speedy responses to stimuli (<100 µs). The transparent photovoltaic mechanoreceptor has a self-operational mode and has flexible options in human electronics.

机械感受器是人体中用于检测来自环境的信号的传感器，它通过大脑诱导身体反应。我们使用金属氧化物异质结设计了一种透明的机械感受器，以开发皮肤采用的概念。使用宽带隙氧化物异质结构在 PET 基板上获得了高度透明的器件 (>60%)。这些层自发地提供光伏功率 (15 μW) 以在没有外部电源系统的情况下操作机械感受器。我们展示了灵活的设备提供了微秒级的快速光响应，为自供电皮肤应用提供了超快机械感受器的解决方案。对于未来的超快电子皮肤，机械感受器还可以在 200 赫兹以上运行。此外，光伏机械感受器可以在与皮肤应用兼容的柔性基板上开发，例如对刺激的快速响应（<100 µs）。透明光伏机械感受器具有自运行模式，在人体电子方面具有灵活的选择。
