Research activities along the lines of the microelectronic and system integration of implantable biomedical microelectronics have started in the 2005’s and have proceeded since then. Some recent and ongoing projects are presented in the following.
Recording systems
Cortical implantable microelectronic systems for epilepsy detection. Development of low-power, low-noise
analog front-ends, as well as mixed-analog digital circuits for signal compression or encoding (e.g., using feature extraction, compressed sensing, Hadamard encoding, etc.).
Stimulation systems
Circuits and systems for deep-brain and cortical stimulation for Parkinson’s disease neuromodulation, epilepsy
control, and stroke rehabilitation. Development of analog circuits for brain tissue stimulation and charge
balancing.
Closed loop implantable microelectronic systems
Circuits and systems for feature extraction and classification applying AI, deep-learning algorithms (e.g., GRU, SVM, etc.). System control of implants, and data transmission to the outside of the body.
