Quad Industries’ client TMSi, a company specialising in EEG and HD-EMG research, wanted to advance muscle activity monitoring by creating a new textile HD-EMG grid that would address the limitations of using rigid traditional grids.
These innovative textile grids are made with a flexible material that forms perfectly to the skin, minimising the chance of movement artifacts during muscle contractions and dynamic movements even when measuring difficult muscle locations. Additionally, the pre-applied double-sided adhesive makes preparation quicker and easier.
Printing on a small flexible material
The client turned to Quad facing challenges getting all necessary circuitry printed on a small flexible material from other developers. Through Quad’s extensive research and optimisation of various components such as substrate, mesh, screen, and paste, they managed to screen print conductive tracks as narrow as a few 100 micrometers with minimal spacing. This was a difficult task, but Quad Industries’ yearlong expertise in screen printing electronics and their skilled operators made it happen.
