We live in a world that’s full of transducers, very tiny ones, which you can’t see, embedded in MEMS and larger ones which, well, you can see. Your smartphone is full of transducers. And when your fridge makes a noise because the door has been open too long that’s all about transducers as well. Transducers exist since decades and as technology evolved they got smaller and smarter and simply ubiquitous. In today’s digital and connected world of the IoT there are even more transducers that impact your life and will increasingly do so without you probably knowing it.
