Currently, old-style personal Medicare techniques rely mostly on traditional methods, such as cumbersome tools and complicated processes, which can be time consuming and inconvenient in some circumstances. Furthermore, such old methods need the use of heavy equipment, blood draws, and traditional bench-top testing procedures. Invasive ways of acquiring test samples can potentially cause patient discomfort and anguish. Wearable sensors, on the other hand, may be attached to numerous body areas to capture diverse biochemical and physiological characteristics as a developing analytical tool. Physical, chemical, and biological data transferred via the skin are used to monitor health in various circumstances. Wearable sensors can assess the aberrant conditions of the physical or chemical components of the human body in real time, exposing the body state in time, thanks to unintrusive sampling and high accuracy. Most commercially available wearable gadgets are mechanically hard components attached to bands and worn on the wrist, with form factors ultimately constrained by the size and weight of the batteries required for the power supply. Basic physiological signals comprise a lot of health-related data. The estimation of critical physiological characteristics, such as pulse inconstancy or variability using photoplethysmography (PPG) and oxygen saturation in arterial blood using pulse oximetry, is possible by utilizing an analysis of the pulsatile component of the bloodstream. Wearable gadgets with "skin-like" qualities are a new type of automation that is only starting to make its way out of research labs and into pre-commercial prototypes. Flexible skin-like sensing devices have accomplished several functionalities previously inaccessible for typical sensing devices due to their deformability, lightness, portability, and flexibility. In this paper, we studied the recent advancement in battery-powered wearable sensors established on optical phenomena and skin-like battery-free sensors, which brings a breakthrough in wearable sensing automation.
目前，老式的个人医疗保险技术主要依赖传统方法，比如笨重的工具和复杂的流程，在某些情况下可能既耗时又不方便。此外，这些老式方法需要使用重型设备、采血以及传统的台式检测程序。获取检测样本的侵入性方式可能会给患者带来不适和痛苦。另一方面，可穿戴传感器作为一种新兴的分析工具，可以附着在身体的多个部位，以捕捉各种生化和生理特征。通过皮肤传输的物理、化学和生物数据可用于在各种情况下监测健康状况。由于采样非侵入性且精度高，可穿戴传感器能够实时评估人体物理或化学成分的异常状况，及时揭示身体状态。大多数市面上的可穿戴设备是附着在腕带并戴在手腕上的机械硬组件，其外形最终受供电所需电池的尺寸和重量限制。基本生理信号包含大量与健康相关的数据。通过分析血流的脉动成分，可以利用光电容积脉搏波描记法（PPG）估计关键生理特征（如脉搏不稳定性或变异性），并利用脉搏血氧饱和度测定法估计动脉血中的氧饱和度。具有“类皮肤”特性的可穿戴设备是一种新型自动化设备，才刚刚开始走出研究实验室，进入商业前的原型阶段。柔性类皮肤传感设备由于其可变形性、轻便性、便携性和灵活性，已经实现了一些典型传感设备以前无法实现的功能。在本文中，我们研究了基于光学现象的电池供电可穿戴传感器和类皮肤无电池传感器的最新进展，这在可穿戴传感自动化方面带来了突破。
