| Summary: | 碩士 === 中華大學 === 機械工程學系碩士班 === 101 === Translation motion, the position of the object changes with time, but the object may also be moved around a certain point or fixed axis, constantly rotating in the original position, we call this motion as a rotary motion (Rotational motion). In daily life, we are exposed rotating motions. Such as electric fan, pulleys, wheels, propeller and record player use rotation to achieve their mechanical effects. In fact the most common movement is moving and rotating mixture of motions, such as automobiles, the wheel rotation of cars. The investigation was divided into two parts: First, the measured micro-motor measurement verification. Second ,energy harvesting circuit design. To validate the existing micro-motor retrieve instantaneous energy capacity, as the voltage is increased, the experimental diodes and capacitors constituting a voltage doubler rectifying circuit, so that the voltage extracted from the micro-motor.
The innovative approach of energy harvesting is to capture fragmented energy and combines the use of micro-electromechanical (MEMS) integration, so that the circuit as an autonomous system to achieve the goal of self-sufficiency in power. This study shows that micro-motor not only can be a micro-generator to capture fragmented energy, but also have the ability to capture an instantaneous energy. By using this result, the energy can be captured from uncollected daily rotational mechanical energy in high efficiency and low cost to replace the traditional battery power of wireless sensor and applying to a building to reduce energy waste of wiring, and increase internal aesthetic to achieve wisdom green building goals.
