Self-powered gait pattern-based identity recognition by a soft and stretchable triboelectric band

Recent Advances in Triboelectric Nanogenerator‐Based Health Monitoring

“…The motion of the muscle or body has relatively large displacement, and thereby is relatively easy for TENGs to detect. The TENG‐based self‐powered muscle/body motion sensors can not only detect the qualitative but also detect the quantitative information of the motion . Yi et al reported a stretchable‐rubber‐based TENG that works based on the in‐plane charge contact/separation induced by the shape change of the rubber ( Figure a–c) .…”

“…Gait monitoring is critical for clinical biomotion analysis, which can offer useful information for various health‐related applications like preventing falls. Han et al reported a TENG‐based self‐powered band that is capable of detecting gait and recognize identity through gait monitoring ( Figure a–c) . The TENG band is composed of a triboelectric rubber wrapper and physiological saline as the electrode.…”

Progress in wearable electronics/photonics—Moving toward the era of artificial intelligence and internet of things

“…Third, technology fusion of wearable systems and AI is reviewed, showing the emergence and rapid development of intelligent/smart systems. In the end, perspectives about the development trends of the next‐generation wearable electronics/photonics are provided, that is, innovating toward multifunctional, self‐sustainable, and intelligent wearable systems in the AI/IoT era 56‐61 …”
