Speaker Biography (Peter Spies)

Dr. Peter Spies studied Electrical Engineering at the University of Erlangen / Germany and graduated with a Dipl.-Ing. degree in 1997. In 2010, he finished his PhD thesis on the topic of power saving in mobile communication devices.
 
Since 1998, he is with the Fraunhofer IIS, power efficient systems department. He was working on the field of multi-standard front-ends and system simulations for communication applications. Since 2001 he is group manager of the "integrated energy supplies" group where he is doing research and design on the field of power and battery management, energy transmission and energy harvesting. Focus of his group is integrated circuit and system design as well as software development. Most important applications are wireless sensor networks or hybrid and electrical vehicles.

Company Profile (Fraunhofer Institute for Integrated Circuits IIS)

Founded in 1985, Fraunhofer Institute for Integrated Circuits IIS in Erlangen, Germany, ranks first among the Fraunhofer Institutes concerning headcount and revenues. With the development of the audio coding method MPEG Layer-3, short MP3, Fraunhofer IIS has reached a worldwide recognition.
 
In close cooperation with our partners and clients we provide our research and development services in the following areas: Digital radio broadcasting systems, audio and multimedia technology, digital cinema systems, design automation and integrated circuits, wired, wireless and optical networks, localization and navigation, high-speed camera systems, imaging systems and nanofocus X-ray technology, medical sensor solutions and communications technology in transport and logistics.
 
"The group 'integrated energy supplies' carries out research and development in the field of energy harvesting, power and battery management. High-efficient voltage converters and charge circuits for different kinds of energy harvesting transducers are subject of the developments as well as complete energy supply systems which use thermal gradients, light or vibrations to power wireless transceivers and sensors. A further focus are battery management systems for different kinds of batteries, which estimate SOC and SOH and keep the batteries in the optimum operation range to achieve maximum performance and lifetime."
