Towards a Wearable Device for Deep Brain Signals Monitoring

Deep brain stimulation (DBS) is a surgical treatment for movement disorders like Parkison's disease or essential tremor. Although DBS is effective in the treatment, the mechanism of action is not clearly understood by now. The accessibility to deep brain regions through the DBS implanted electrodes can give the opportunity to monitor the local activity of nuclei once accessible only during surgical operations. Monitoring extensively the signals from these regions can constitute an added value in understanding the mechanism of action of movement disorders as well as DBS. In this work a first prototype of wearable device for DBS recordings is proposed. The proposed device is portable and modular and demonstrated to be suitable in conditioning extremely low voltage signals like local field potentials (LFP) are
