可穿戴医疗保健为持续、实时和非侵入性的健康状态监控提供了令人兴奋的机会。尽管电化学和光学传感已经取得了很大的进步，但在小型化、耐磨性、符合性和延伸性方面仍然存在着对替代信号转换的迫切需求。基于机械的传感，指的是将生物信号有效地转换成可测量的机械信号，被认为具有上述理想的特性和超灵敏。在这一概念中，重点介绍了基于可穿戴医疗保健的微/纳米结构的压力、应变、偏转和肿胀传感原理。重点介绍了基于压力/应变的生物物理传感器和基于微流控压力、微悬臂梁和光子晶体的生物化学传感器。在样品采集、小型化和无线数据读取方面，仍有许多挑战需要面对。随着解决这些问题的不断努力，基于机械的传感有望为集成了物理、电生理和生化传感器的多模式可穿戴医疗系统提供一条可访问的路线。
Wearable healthcare presents exciting opportunities for continuous, real-time, and noninvasive monitoring of health status. Even though electrochemical and optical sensing have already made great advances, there is still an urgent demand for alternative signal transformation in terms of miniaturization, wearability, conformability, and stretchability. Mechano-based transductive sensing, referred to the efficient transformation of biosignals into measureable mechanical signals, is claimed to exhibit the aforementioned desirable properties, and ultrasensitivity. In this Concept, a focus on pressure, strain, deflection, and swelling transductive principles based on micro-/nanostructures for wearable healthcare is presented. Special attention is paid to biophysical sensors based on pressure/strain, and biochemical sensors based on microfluidic pressure, microcantilever, and photonic crystals. There are still many challenges to be confronted in terms of sample collection, miniaturization, and wireless data readout. With continuing efforts toward solving those problems, it is anticipated that mechano-based transduction will provide an accessible route for multimode wearable healthcare systems integrated with physical, electrophysiological, and biochemical sensors.
