ABSTRACT
Emerging technological requirements in bioelectronics gadgets have compelled researchers to look out for devices that do away with the traditional batteries that are bulkier, have a limited lifetime, and make it impossible to fabricate miniaturized devices. Self-powered technology is a promising area where the devices are powered by mechanical movements of the body, and photovoltaic batteries capable of generating enough power to run these devices. With nanotechnology and significant breakthroughs in materials science, devices relying on these technologies are smaller, capable of functioning independently, and therefore have the liberty of being wearable. Furthermore, the associated devices offer enormous health care benefits, a better quality of life, and personalized care for each individual. The crucial part of designing the gadgets is invariably the technology associated with harvesting such energies. However, many areas where further innovations are required are identified, and recommendations to tackle them are presented. Additionally, state-of-the-art technologies come at a cost. The devices must be designed to be cost-effective to be accessible for most of the population. Such requirements have made it essential for materials scientists, clinicians, biologists, and engineers to work together on a common platform and make user-friendly, rugged, and efficient devices that are economically viable.
