Skip to 0 minutes and 7 seconds Welcome to week one of Electrify, your taster of electrical and electronic engineering. This week, we’re talking about the interface between electrical and mechanical engineering. This is known as electromechanics. So this is how electrical and electronic systems interface with the mechanical or the physical world. We’ve got a really good example of one of these behind me. You’ll probably be able to see these wind turbines on the Mersey.

And that’s generating electricity which is transmitted through the grid, into your house, and that powers the internet and the computer that makes you able to watch this video. So that’s a big thing that’s interfaced between the physical and the electrical world. On a smaller scale, here’s a good example, too. Here’s my key to unlock my car. I press one of these buttons. That transmits an electrical signal. And that electrical signal is then used to release the mechanical locks on the car doors. So that’s what this module is all about.
Skip to 1 minute and 14 seconds In this week, we’re going to be covering how do we interface between things we can press and touch and feel and the electrical systems we often need to control them. Welcome to Electrify.
In this first week Dr Leah Ridgway is going to introduce electromechanics and talk in more depth about how electricity interfaces with mechanical devices. Standing on the roof of the Electrical Engineering building at the University of Liverpool, she shows one real life use of Electromechanics as we gaze upon the River Mersey.
