MST / MEMS / Nano

Tiny but intelligent.

At the Personal Devices or also at the car, MEMS set the tone. And they are the drivers of IoT, the Internet of Things. A new industry is emerging that is generating new ideas and applications every day. We help to produce the technologies for it, from development to the finished product.
