The sensors for the detailed recording of body data have to be super light, flexible and a perfect fit. To do this, the body part in question is first scanned in three dimensions. The 3D model is transformed into 2D and output with a printer - and later fits like a glove.
A flexible PCB is produced for the carrier area – with the LPKF ProtoLaser U4. The video linked below provides an impression of this, starting around minute 2. The ProtoLaser structures the flexible circuit and then safely separates it from the material. In this way, specific components for recording and transmitting a wide variety of measurement data can be precisely fitted to the planned part of the body. Link to the video
