Abstract

Battery has always been the conventional option to supply power in electronic systems, particularly mobile devices. However, it’s no longer feasible to use battery in mobile and wearable electronic as it is bulky and heavy to be carried around with mobile devices. These days with the development of mobile and wearable technology, the demand for low-power and portable energy sources can no longer be avoided. This project aims to design and develop a human-powered wearable electronics based on piezoelectric generation system. By this, it aims to power a simple computer system with a ceramic piezoelectric material based on impact from the users. With impact from the user’s feet, the piezoelectric generates electricity that is channeled into the circuit. The computer system detects the temperature of the shoes by use of a temperature sensor and processes the information in a microcontroller. The microcontroller coded in C++ then triggers the LED when it detects the temperature above 25°. A prototype of this wearable electronic is then fabricated to demonstrate the ability of the piezoelectric in powering a simple computer system. More importantly, the proposed power generation system will contribute to the green technology application in our daily life. Experiments and tests were carried out to measure the effectiveness of the system.
