8 JEJU NATIONAL UNIVERSITY SELF-CHARGING SUPERCAPACITOR POWER CELL (SCSPC) Energy conversion and storage are the two prime technologies in the field of energy science separated by their own distinct mechanism; however, integrating both in a single device is of great interest in the energy sector. Hence the device developed by integrating the energy conversion and storage in a single cell is termed the Self-Charging Supercapacitor Power Cell (SCSPC). Among various energy conversion systems, bio-mechanical energy conversion is optimum for the design of the SCSPC since it can convert low-frequency/biomechanical energy into electricity whereas, in energy storage, supercapacitors are the favorite due to the rapid charging/discharging and high power compared to that of batteries. Our proposed research idea is to hybridize the energy conversion and storage in a single cell, which generates electricity when the force is applied, and simultaneously the produced electricity is stored in the form of electrochemical energy with improved self-charging efficiency in SCSPC device. The proposed SCSPC paves the way for developing maintenance-free autonomous power systems for the portable energy sector.
