This page is designed as a platform for me to write about my final semester minor project & thesis. The topics is "Novel Actuation Method for Electro-Magnetic Micro Relays".
As most electronic engineers aware that the use of a relay or solenoid valve would consume huge amount of energy. For some application, using relay or solenoid would not be worthwhile especially if batteries are the main power source.
The theory behind the topic of this project is that by applying repetitive pulse signal to energize the relay would reduce the amount of power consumed. This repetitive pulse signal will be adjusted according to the cantilever's natural frequency to make it wobbles. Once the cantilever starts swinging, more and more pulse will enhance the wobling and finally the end contact of the cantilever touches the connector thus completing the circuit.
The connection of the cantilever and the connector will be held firm by permanent magnet attached with the system. This will minimise the use of current to stick them together as in conventional relays.
