Nanogenerator-induced personalized wearable health monitoring electronics: A review

Abstract

The fusion of triboelectric nanogenerators and piezoelectric nanogenerators with healthcare biosensors represents a pioneering synergy, propelling wearable technologies into a new era. These nanogenerators have a remarkable ability to harness energy from mechanical movements and seamlessly integrate with biosensors, creating self-powered systems that redefine the landscape of healthcare monitoring. Beyond merely providing power, this integration facilitates continuous, noninvasive monitoring of vital physiological signals such as heart rate and pulse. Nanogenerator-powered biosensors offer a sustainable and environmentally friendly approach by harvesting energy from user movements, blood flow, and heartbeat. This transformative combination not only increases the accessibility and efficiency of wearable health technologies but also paves the way for personalized and comprehensive health monitoring. The potential for a greener and more integrated future in wearable biosensing becomes evident through nanogenerators' environmentally conscious energy-harvesting mechanism. Adding a layer of sophistication, integrating deep learning and machine learning models further propels the capabilities of nanogenerator-powered biosensors. These systems generate intelligent actions in specific situations by using training data and experiences to refine algorithmic models. Thus, the system can formulate appropriate responses and predictions based on acquired knowledge and insights. These insights are invaluable to chronic illnesses such as diabetes or cardiovascular diseases, contributing significantly to the diagnosis and treatment processes.
