Wearable Nano sensors for Continuous Health Monitoring Application

The common trends in healthcare are that it is a paradigm shift in healthcare movement towards a continuous and personalized health management as opposed to episodic and hospital-centric care. This iserosive change spurred by the emergence of wearable nano sensors that can combine superior nanotechnology with bioelectronics in order to facilitate a real-time understanding of human health like never before. This review article offers a complete overview of principles, materials, fabrication, and applications of wearable nano sensors. It presents the cornerstone advantages of nanomaterials, including ultra-high sensitivity, miniaturization, and biocompatibility, which allow the tracking a broad spectrum of physiological and biochemical biomarkers. The report examines in detail novel fabrication methods, such as electrospinning and inkjet printing, and describes the pressing problem of power requirements with novel energy harvesting methods. It also looks further into the clinical utility of such devices in the treatment of chronic illnesses and the cutting-edge applications they are becoming in advanced systems such as BMIs and prosthetics. Lastly, an appraisal of the technical, biological and ethical issues, e.g., foreign body reaction, nano toxicity, data privacy and equity is provided. The conclusion of the analysis is that an ethical approach to implementing this technology into comprehensive clinical use can depend on a unified strategy that incorporates resilient materials science, low-power electronics, sophisticated data analytics, and an active ethical perspective.
