SE7: Next-Generation Energy-Scavenging Systems
Organizer: Anantha Chandrakasan, MIT, Cambridge, MA
Chair: Uming Ko, Texas Instruments, Dallas, TX
Christian Enz, CSEM SA, Neuchâtel, Switzerland
A decade of R&D in energy scavenging has resulted in micro-generators based on
photovoltaic, vibration, and thermal mechanisms that produce 10’s to 100’s microwatts
of power. These generators could power ultra-low-power portable devices from sensors
and embedded processors to MP3 players, medical electronics, etc. More recently, there
has also been a push towards wireless power transfer that can provide energy to higherpower
portable equipment or appliances. The next step is to design 2 nd -generation
energy scavenging systems that optimize generators, conversion circuits, load
electronics and energy storage that “buffers” the variations of scavenged energy. The
challenges to achieve “fully autonomous operation” or “green portable” will be power
efficiency, versatility, miniaturization, weight, and cost! The overall vision, advancement,
and practical limits of various techniques will be discussed.

E2: MID – ‘Scaled Down’ PC or ‘Souped Up’ Handheld?
Co-Organizers: Yiwan Wong, Samsung, Yougin, Gyeonggi, Korea
Raney Southerland, ARM, Austin, TX
Moderator: Jan Rabaey, University of California, Berkeley, CA
The new emerging Mobile Internet Device (MID) market has quite a few dynamics
going on for what seems to be a promising driver for future consumer electronic
equipment growth. This means that existing high-performance, personal-computerfocused,
CPU architectures will need to reduce power consumption, and existing
consumer-focused, low-power, embedded-core architectures will need to improve
performance. Players in this space are not limited to the CPU core providers, but also
platforms, consumer equipment makers, computer makers, software providers, etc.
Discussion will include: how one or the other architectures is best fitted, strategies if
appropriate, and how the eco system will all be tied together.
