Piezo-tribo dual effect hybrid nanogenerators for health monitoring

Over the years, nanogenerators for health monitoring have become more and attractive as they provide a cost-effective continuous way to successfully measure vital signs, physiological status, environmental changes in/around person. Using such sensors can positively affect healthcare workers diagnose prevent life-threatening conditions. Recently, dual piezo-tribological effect of hybrid (HBNGs) subject investigation, substantial amount data, which is significant healthcare. However, real-life exploitation these HBNGs in still marginal. This review covers piezo-tribo dual-effect that are used different movements human body blood circulation, respiration, muscle contractions. Piezo-tribo applicable within various settings means powering noninvasive sensors, providing capability constant patient without interfering with range motion or comfort user. also intends suggest future improvements HBNGs. These include incorporating surface modification techniques, utilizing nanowires, nanoparticle technologies, other chemical modifications. contribute significantly terms electrical output enhance their prospects applications field monitoring, well vitro/in vivo biomedical applications. While promising option, improved lacking. discusses technical issue has prevented so far, real use sensors.
