Ultrasound Energy and Data Transfer for Medical Implants

Franceco Mazzilli was born in Turin, Italy, in 1983. He received the B.Sc. degree in electrical engineering from the Polytechnic University of Turin, Turin, Italy, in 2005, the M.Sc. degree in micro- and nano-technologies for integrated systems, issued jointly from the Institut National Polytechnique de Grenoble, Grenoble, France, and Ecole Polytechnique Federale de Lausanne (EPFL), Lausanne, Switzerland, in 2007, and the Ph.D. degree in microsystems and microelectronics from EPFL in 2013. In March 2008, he joined the Electronics Lab at EPFL as a Research Assistant in the field of RFIC design. His research interests include analog and RF CMOS circuit design for power management, wireless systems, and MEMS/NEMS applications. He is an analog design engineer at Melexis Technologies SA in Chemin Bevaix, Switzerland. Catherine Dehollain received the Master Degree in Electrical Engineering in 1982 from EPFL. Then, sheworked in Geneva up to 1990 as a Senior Design Engineer in telecommunications at the Europeanresearch center of Motorola. From 1990 up to 1995, shedidher PhD thesis at the Chaire des Circuits et Systemes at EPFL in the domain of impedancebroadbandmatching circuits. Since 1995, sheisresponsible at EPFL for the RFIC group. She has participated to differentSwissresearchprojects as well as European projectsdedicated to data communication of sensorsnodes (e.g. MuMoR, Minami Europeanprojects) as well as remotepowering of sensornodes. Her main domains of interest are telecom applications (e.g. Impulse radio Ultra-Wide Band, super-regenerative receivers, RFIDs)as well as biomedical applications. She has been the coordinator of Europeanprojects (e.g. FP6 SUPREGE, FP7 Ultrasponder)and of Swissprojects (e.g. CAPED CTI project, NEURO-IC SNF project).
