Abstract
The utilization of kinetic energy from fluid flow to power sensory systems is experiencing an all-time high research focus. Invention of nanogenerators have fueled this research focus with unprecedented flexibility of applications. Many studies have reported on utilizing the mechanism of nanogenerator for sensing fluid flow. In this short work, we have summarized different types of self-powered nanogenerator-based flow sensors and their applications. We have also classified the use of Nanogenerator based flow sensors in different fields, such as Bio-medical Application, Fluid velocity sensing, and Chemical Detection. In the Bio-medical field, the flow sensor can be used for the patient’s infusion process and respiratory monitoring. In the fluid velocity sensing field, the flow sensor can work as a detector for the airflow and humidity percentage. The sensor can act as an anemometer (wind flow meter), Wind Vector Sensor, along with velocity measurement. In the reported chemical detection application, a nanogenerator was used to analyze the alcohol breath and measure the rising speed of bubbles of the coal bed. All these discussed flow sensors demonstrated the ability to scavenge energy while acting as a potential sensor. We further included that, most of the reported flow sensors are triboelectric, piezoelectric, and electromagnetic nanogenerator mechanisms. The hybrid system of nanogenerators was also reported. These engineered sensors can be the cutting-edge solution for several problems on current flow sensing problems and future obstacles. In this work, a Rotating Sliding mode Triboelectric Nanogenerator (RS-TENG) was designed. Teflon (PTFE) tape was introduced to work as a tribo-negative layer and the copper sheet and copper tape were worked as an electrode, whereas the adhesive tape was used between two PTFE tapes to create multiphase TENG. This RS-TENG was fabricated to demonstrate the applications as a self-powered flowmeter for detecting wind speed. Also, in this thesis, we have included an experimental study of triboelectric nanogenerator bases self-powered flow sensors. The experimented flow sensor demonstrated a promising result and potentials to be used in industrial applications.
