The produced device should be able to charge a battery while the user is on the move without needing an external power supply. Electromagnetic conversion is the only
viable way to convert kinetic energy into electricity. It is based on a flux created by the movement of a magnet along a coil. The magnet moves, either rotating or
translating, along a coil of electricity wire. The movement causes induction and supplies a current in the wire.
1.2 Objective
The main goal of this project is to design LED torch that operates using kinetic energy that is the concept of energy harvesting. The followings are the
objectives that must be met in the development of this project: An alternative power source that could circumvent the problem of battery
lacks in LED torch. To analyze the electromagnetic generator as a energy conversion to convert
the kinetic energy into electricity To design the LED torch that operates using kinetic energy from human
body movement
1.7 Problem Statement
Almost all LED torch used today are powered by two or more alkaline batteries. Often torch fail to operate when they are needed the most, such as during
power-failures. This may be due to leaks in the batteries or a result of the batteries decaying. Therefore, in times of emergency, it is unreliable to depend on batteries to
power the only light source available. An alternative energy source, that is available anytime, would have to
be found to ensure that the torch works when needed. With the realization of the project, the batteries utilization needed for the torch that using by the user will be
reduce and the bulb of the torch can be light up one while on the move. The design of the project also enables the user to be ever equipped with an extra charged battery
whenever he needs one.
1.8 Scope
This project will discover certain area of development which stated in the scopes below
An analysis of human power which is the human power is defined and the history and the preceding research are described.
Research and analysis of the electromagnetic generator, the type of
electromagnetic generator and all related calculations.
Construct the circuit for simulation purpose which then will be tested to
ensure the targeted output
Product is design for users convenient when using the LED torch, without worrying power failure to lighting up the bulb due the lack of battery EMF.
