Study and performance analysis of harvested energy in different scenarios and its suitability in different applications

Abstract

Wireless body area network (WBAN) has evolved from wireless personal area network newline(WPAN), a prominent area of research with vast applications in different fields. In WBAN, newlinedifferent wirelessly interconnected body nodes (BNs) are implanted in or around the human newlinebody. With the advancement in technology, miniature low power devices/ BN are developed in newlinehealthcare, military and fitness applications. In WBAN, BNs are implanted inside and on the newlinehuman body to measure physiological signals using various sensors, such as electrocardiograph newline(ECG), electroencephalogram (EEG), blood pressure, temperature etc. of the body, which newlinecollects data and sends it to the sink node. newlineAlthough with the advancement of various body sensors (BS), many BNs are available but still newlinethere is a need of small and energy efficient wireless BN. In the present work, a small and newlineefficient wireless BNs with compact and high capacity battery is proposed. In this work, energy newlineis harvested from an ambient source such as vibration, pressure, light, heat and many more. newlineGenerally, researchers have used piezoelectric sensors, electromagnetic or solar harvesters. In newlinethis work, the concept of energy harvesting is proposed using the hybrid optimization of newlinepiezoelectric and peltier harvester by controlling the switching operation at various stages by newlinedeveloping an algorithm using matrix laboratory (MATLAB). newline
