FABRICATION OF TRANSITION METAL NITRIDE THIN FILM BASED BIOCOMPATIBLE AND FLEXIBLE SUPERCAPACITORS

Abstract

The development of energy sources for implantable biomedical electronics has allowed the devices to be deployed effectively and to treat disease in humans. Implanted medical devices provide continuous monitoring and therapy on a regular schedule or based on patient needs (biological investigation, prognosis, and diagnosis). There are currently millions of implantable medical devices available worldwide for serving/helping living body for better health. Most of them rely on a permanent and sufficient power supply. Unfortunately, the non-biocompatibility of these energy sources can severely affect the wearer's life. The concept of flexible electronic devices that will exist in the near future is fascinating. Implantable devices are predicted to be a feature of the next generation of electronics. They are becoming increasingly popular because of the increasing number of chronic disease patients, health monitoring initiatives and population of elderly people. Researchers have recently published several studies examining the bio-implantable components of microchips, heart valves, and artificial organ transplants that can be used as biological transplants for chronic diseases. To revolutionize the field of implantable devices and raise living standards, it will be necessary to fabricate inexpensive, biocompatible, reliable, and long-lasting energy storage devices. With the rapidly increasing demand for wearable, implantable, and portable electronic energy storage devices, the fabrication and design of energy storage devices are becoming essential. In a wearable and implantable electronic device, a flexible supercapacitor with a prolonged life span, high biocompatibility, and exceptional electrochemical performance would be ideal. Therefore, it is imperative in this regard to utilize thin-film-based flexible and biocompatible supercapacitors. Smart supercapacitors are an efficient energy storage solution to the growing energy demands from technology commercialization, as we strive to pursue a future with sustainable and efficient energy. Supercapacitors have emerged as promising candidates for these applications due to their high-power density, fast charge/discharge rates, and long cycle life. They have become a promising energy storage technology for a variety of applications, including wearable and implantable medical devices. The development of flexible and biocompatible supercapacitors is crucial for the advancement of such devices, as it allows for conformal and comfortable integration with the human body. One of the key challenges in developing such devices is the limited availability of suitable electrode materials that offer high conductivity, stability, and biocompatibility.
