ABSTRACT

Technological evolution has created an indispensable impact on mankind across the globe by transforming the standards of lifestyle. The demand for customizable electronic tools that revolve around miniaturization, flexibility, cost-effectiveness and ease to use has drastically enhanced the scope of developing various systems in the biomedical and healthcare industry with the incorporation of intelligent algorithms for acquiring the data of a person which is analyzed with the help of Internet of Things (IoT). Nanotechnology has immensely contributed towards achieving a multifunctional real-time health monitoring system that addresses the challenges involved to track the vital body signals, for instance, heart rate, pressure levels, body temperature, etc. by the fusion of nanomaterials. They can analyze the minute changes that occur in our bodies due to the size of the fabricated sensors with high sensitivity and reliability. The right choice of materials, simple architecture of the device, fabrication techniques, target substance, and so on are the fascinating features that describe possible solutions to build an eco-friendly device. The power consumed to sustain the functionality of the device is substituted by energy harvesters, which scavenges the energy from the existing resources for driving low-power electronics that assist in developing a sustainable society. This chapter discusses the different energy conversion mechanisms focusing mainly on nanogenerator concept and available PENG/TENG based sensors in healthcare.
