Embedded Signal Processing

Electrophysiological signals - be it from single cell recordings or from ExG recordings - have an electrical amplitude in the µV range. For further technical use, they need at least to be amplified in a wide frequency band to make them accessible for automated analysis.

Signal conditioning was up till recently done most of the time by commercial systems, but now we are working on a glass fibre based, medical grade 64 channel amplifier.

Embedded and handheld data acquisition

Future implantable signal processing systems require minimal power consumption with maximal computing power. We investigate the use of commercially available embedded and handheld hardware. In fact we use the same hardware as can be found in high end cell and smart phones.
