Biography
During his master thesis, supervised by Prof. Danilo Demarchi from Politecnico di Torino and titled “Body Dust: Feasibility study on signal transmission for sub-100μm-size active wireless biosensors”, he spent a semester of research at Integrated Circuit Laboratory (ICLAB) of Neuchâtel under the supervision of Prof. Sandro Carrara from École Polytechnique Fédérale de Lausanne (EPFL), Switzerland. He discusses about the feasibility on creating an UltraSound (US) communication circuit to wirelessly transmit outside the body diagnostic information from multiplexed biosensors chip built on the top layer of a drinkable CMOS “Body Dust” cube. The results of the feasibility study have been published showing promising results with sub-10 µW of power consumption and a total chip area of 43 x 44 µm2.
He was a Research Assistant at the Department of Electronic Engineering (DET) of Politecnico di Torino.
Actually he is conducting his PhD focusing on design and fabrication of analog and digital circuits for ultra-miniaturized CMOS for vision prosthesis, directed by Prof. Diego Ghezzi at Medtronic Chair in Neuroengineering in Geneva and co-directed by Prof. Sandro Carrara at ICLAB in Neuchâtel.

Miniaturised Wireless Power Transfer Systems for Neurostimulation: A Review
In neurostimulation, wireless power transfer is an efficient technology to overcome several limitations affecting medical devices currently used in clinical practice. Several methods were developed over the years for wireless power transfer. In this review article, we report and discuss the three most relevant methodologies for extremely miniaturised implantable neurostimulator: ultrasound coupling, inductive coupling and capacitive coupling. For each powering method, the discussion starts describing the physical working principle. In particular, we focus on the challenges given by the miniaturisation of the implanted integrated circuits and the related ad-hoc solutions for wireless power transfer. Then, we present recent developments and progresses in wireless power transfer for biomedical applications. Last, we compare each technique based on key performance indicators to highlight the most relevant and innovative solutions suitable for neurostimulation, with the gaze turned towards miniaturisation.
