DESCRIPTION:Dehollain Catherine\nAbstract:\nIn the case of an implanted me
 dical device (IMD)\, it is important to design an implant which can be rem
 otely powered by the external base station through (e.g.) near-field induc
 tive coupling in order to avoid surgery to replace the battery. Moreover\,
  the IMD needs to exchange key information with the external base station 
 through radio frequency communication. First\, the base station needs to s
 end energy wirelessly to the IMD. This energy is stored in a load capacito
 r or is used to recharge a medical grade battery. Then\, the sensor which 
 is part of the IMD performs a measurement (e.g. measurement of the interna
 l temperature) which is transformed in a digital signal thanks to an analo
 g to digital converter. This digital signal modulates the carrier of the i
 mplanted transmitter to generate the modulated signal which is sent wirele
 ssly to the receiver of the external base station. Therefore\, wireless re
 mote powering and wireless data communication will constitute the main obj
 ectives of this talk. Different practical examples will be presented (e.g.
  implanted brain interface\, monitoring of a small rodent\, etc).\n\nShort
  biography:\nCatherine Dehollain received the Master’s degree in electri
 cal engineering and the Ph.D. degree from EPFL in 1982 and 1995\, respecti
 vely. From 1982 to 1984\, she was a Research Assistant at EPFL. In 1984\, 
 she joined the Motorola European Center for Research and Development\, Swi
 tzerland\, where she designed integrated circuits applied to telecommunica
 tions. In 1990\, she joined EPFL as a Senior Assistant where she performed
  her PhD thesis on impedance broadband matching. Since 1995\, she is respo
 nsible at EPFL of the RFIC Group dedicated to radio frequencies activities
 . From 2006 to 2014\, she was a Maître d’Enseignement et de Recherche (
 MER) at EPFL. Since 2014\, she has been Adjunct Professor at EPFL. She is 
 an author or coauthor of 7 scientific books and of 200 scientific public
 ations. Her research interests include biomedical remotely powered sensors
 \, RFIDs\, RF circuits\, low power analog circuits\, and electrical filter
