Silk fibroin/Ag nanowire-based multifunctional sensor for wearable self-powered wireless multi-sensing microsystems

Recent progress in self-healable energy harvesting and storage devices – a future direction for reliable and safe electronics

“…Shifting from regular electrodes, gel based electrodes brought in different advantages such as flexible, stretchable, and fireproof properties, demonstrating their potential application in real-time self-powered energy harvesting, sensing, human body motion detection, personal power sources, E-skin, actuators, cloth-based biomedical sensing, and human–machine interactions. 65–69 Recently, Tran et al have demonstrated completely fiber based TENG with breathable, washable and SH features. Polybutadiene based urethane (PBU) was chosen as the charge generating layer and PVDF as the tribonegative layer.…”

Silk Fibroin-Based Triboelectric Nanogenerators for Energy Harvesting and Biomedical Applications

“…Wen et al developed an optimized mask spraying technique (Figure b) for the fabrication of functional sensing layers with internal cross-linked AgNW network structures . First, a mixture of SF solution, AgNW solution, and glycerol was prepared at a specific weight ratio and stirred thoroughly to obtain the SF/AgNW mixture.…”

“…Leveraging the multifaceted sensing properties of their TENGs and the autonomous nature of the microsystem, the harvested electrical energy efficiently powers the sensors. The developed sensors enable the detection of environmental variables, and the acquired sensing data are wirelessly transmitted in real time to a mobile phone via an internal Bluetooth connection, as illustrated in Figure b . Narendar Gogurla and Sunghwan Kim’s electronic tattoo facilitates human motion monitoring by detecting joint movements throughout the body, simultaneously providing visual and tactile stimulation. , Figure c shows the real-time output voltage signals obtained from the attached electronic tattoos on various body parts.…”

High Signal to Noise Ratio Piezoelectric Thin Film Sensor Based on Elastomer Amplification for Ambulatory Blood Pressure Monitoring

“…Real-time health monitoring technology plays an important role in our daily lives and has made significant breakthroughs in clinical diagnosis. − For example, wearable electronics can dynamically identify abnormal changes in physiological signals such as ECG, sphygmus, and respiration . One of the most extensive areas of research is cardiovascular disease monitoring, including the birth of different principles of pressure sensors, − ultrasound sensors, , and hybrid mechanism sensors, , etc., which provide ideas for cardiovascular prevention. In the early stages of cardiovascular disease, the human body may not have obvious physical symptoms, but detailed changes in pulse waves can reflect the potential risks of the disease .…”
