Abstract

The triboelectric generators works on the principle of voltage produced by charge accumulation as a result of friction between between heterogenous materials. Self powered sensors is the most needed development in medical industry. Biosensors are power supply dependant.The power supply need for biosensors are catered by using mechanical energy harvesting Triboelectric Nano generators (TENGs) working on mechanical energy harvesting method is applied for developing biosensors. TENGs work on the principle, of producing charges carriers by enabling friction between two distinct materials. The generated electric energy acts as a reservoir to power the device. In bioimplantable sensors, power supply systems replacement is complex, as it needs a surgical intervention. Hence heartbeat energy is harvested for the powering pacemakers. Simulation and modelling of contact separation mode based TENGs with Spice (Simulation Program with Integrated Circuit Emphasis) software is discussed in this paper. The signal generation of the TENGs has been simulated by SPICE and analytical samplings have been carried out for the circuit analysis. Recently invented heart rate monitors are not suitable for daily usage. Hence TENGs are identified as cost effective biosensors with unique features such as light weight and high sensitivity.
