“…At the same time, the device unavailability during recharging would disrupt the continuity of the long-term monitoring process. Currently, advances in wireless power supplies, like near-field communication (NFC) or self-powered methods (solar cells and wearable power supply cells that rely on human activities), play an essential role to provide solutions to power the data reading, processing, transmission, and even display modules of sweat sensing platforms [120][121][122].…”

Sweat, as a biofluid with the potential for noninvasive collection, provides profound insights into human health conditions, because it contains various chemicals and information to be utilized for the monitoring of well-being, stress levels, exercise, and nutrition. Recently, wearable sweat sensors have been developed as a promising substitute to conventional laboratory sweat detection methods. Such sensors are promising to realize low-cost, real-time, in situ sweat measurements, and provide great opportunities for health status evaluation analysis based on personalized big data. This review first presents an overview of wearable sweat sensors from the perspective of basic components, including materials and structures for specific sensing applications and modalities. Current strategies and specific methods of the fabrication of wearable power management are also summarized. Finally, current challenges and future directions of wearable sweat sensors are discussed.

“…e main output of the finger bending acquisition sensor is resistance, which needs to be converted into a voltage signal and amplified and filtered, and the resistance value is obtained after ADC collection. At the same time, the circuit uses CC2540s BLE chip as a processor to collect ADC electrical signals and transmit them via bluetooth [20][21][22][23][24][25].…”

This work takes the production and usage scenarios of the data glove as the research object and studies the method of applying the flexible sensor to the data glove. Many studies are also devoted to exploring the transplantation of flexible sensors to data gloves. However, this type of research still lacks the display of specific application scenarios such as gesture recognition or hand rehabilitation training. A small amount of experimental data and theoretical analysis are difficult to promote the development of flexible sensors and flexible data gloves design schemes. Therefore, this study uses the self-made flexible sensor of the research group as the core sensing unit to produce a flexible data glove to monitor the bending changes of the knuckles and then use it for simple gesture recognition and rehabilitation training.

“…As the EMG typically consists of a solid and bulk magnet and the metal coils are usually difficult to be stretched or bent, it is much more challenging to integrate EMG into flexible wearable EHs. Therefore, the integration of TENG and PENG attracts more attention for such designs, and this combination at the same time can leverage the characteristic of human motions, in which the mechanical friction and deformation usually happen concurrently ( Tan et al., 2020 ; Zheng et al., 2017 ; Zou et al., 2020a ). Figures 4 D and 4F show some examples for hybridized TENG and PENG wearable devices through simple structural combination with a multi-layer design.…”

Summary Body sensor network (bodyNET) offers possibilities for future disease diagnosis, preventive health care, rehabilitation, and treatment. However, the eventual realization demands reliable and sustainable power sources. The flourishing energy harvesters (EHs) have provided prominent techniques for practically addressing the concurrent energy issue. Targeting for a specific energy source, wearable EHs with a sole conversion mechanism are well investigated. Hybrid EHs integrating different effects for a single source or multi-sources are attaining growing attention, for they provide another degree of freedom concerning a higher-level energy utility. Merging EHs with other functional electronics, diversified functional self-sustainable systems are developed, paving the way for the accomplishment of bodyNET. This review introduces the evolution of wearable EHs from a single effect to hybridized mechanisms for multiple energy sources and wearable to implantable self-sustainable systems. Last, we provide our perspectives on the future development of hybrid EHs to be more competitive with conventional batteries.
