Custom Bilateral Multichannel Si Brain Probe

Custom Bilateral Multichannel Si Brain Probe Mfg service

We designs and manufactures Bilateral (double-sided) Multichannel Si Brain Probe, developed by use of T-MicroTec's proprietary 3DIC and MEMS process technology, for Brain Signal Recording / Stimulation. The Bilateral Multichannel Si Brain probe, named Neuronode100 series, integrates electrode sites on both Front and Back side for more effective signal recording and stimulation.
