Abstract

If specific biological signals can be precisely monitored, implantable and wearable electronic devices have the potential to enhance the quality of life as well as the life expectancy of a large number of people who suffer from chronic illnesses. It is now possible, as a result of developments in packaging and nanofabrication, to embed a variety of microelectronic and micromechanical sensors (such as gyroscopes, accelerometers, and image sensors) into a small area on a flexible substrate for a relatively low cost. This is made possible by the fact that it is now possible to do so. We analyse the benefits, drawbacks, and likely directions that each approach will go in the future. The idea of generating power for implanted devices by the collection of energy from natural sources and the motion of the human body has recently received new significance. The collection of kinetic, electromagnetic, thermal, and infrared radiant energy are the topics of discussion in this overview. A wide range of biocompatible materials, such as piezoelectric and triboelectric nanogenerators, biofuel cells, and environmental sources, may be used to carry out harvesting procedures. As is the case with all of the techniques for putting biocompatible harvesters into action, some of them have a low rate of power consumption, while others vary according to the device and the location where they are implanted. In this overview, we explore the integration of harvesters into implantable devices, analyse the various materials and approaches, and investigate how new and better circuits will aid generators in maintaining the functionality of medical devices
