 M3. The goal of
the Michigan Micro Mote (M3) project is to finally realize
the Smart Dust vision: networks of integrated, autonomous,
energy-harvesting nodes that can sense the environment and deliver
their data over a wireless mesh network. The concrete goal of the
project is to: (1) create sensor nodes that are cubic-mm in size, (2)
draw ~10 nW, and (3) deliver data every few minutes over a multihop
network. This requires advances in every layer of the system stack --
circuits to memory to processor to timers to radios to interconnects
to packaging to software to protocols to programming models. If
successful, this represents a 1,000-10,000 fold improvement over the
state-of-the-art in size and power.
 HiJack. HiJack is a
hardware/software platform for creating cubic-inch sensor peripherals
for the mobile phone. HiJack devices harvest power and use bandwidth
from the mobile phone's headset interface. Several energy harvesting
power supply designs are possible, with tradeoffs in efficiency, cost,
and complexity. Digital communications of sensor data across the
audio channel offers several coding and compression opportunities.
The HiJack platform enables a new class of small and cheap
phone-centric sensor peripherals that support plug-and-play
operation. HiJack has been tested with the iPhone 3G/3GS/4G, iPod
Touch, and iPad devices. We're working on supporting Android and
Windows Phone 7 devices as well. The HiJack platform has served as
the basis for a number of low-power sensor and signal conditioning
front-ends including EKG (both 3-lead and two hand), gas concentration
(CO, NOx, O3, and SO2), and soil moisture.
Low-Power Software Radio Architectures. "By about 2020
software radios will have become the standard technology for
commercial, as well as military, radios, employed in a range of
devices, from battery-powered sensors and hand-held devices to
plugged-in devices (such as base stations),"
claims
BBN's Craig Partridge. However, one of the chief impediments to
realizing this future is that today's software radios are large,
expensive, and power-hungry, and so they're poorly-suited to
battery-power and hand-held devices. This project explores
clean-slate system architectures for software-defined radios, ranging
from highly-programmble radios to RF front-ends with reconfigurable
hardware baseband processing to simple RF front-ends with pure
software baseband processing. Our chief aim is to make software
radios small, inexpensive, and low-power. Today, we have an
802.15.4-compatible SDR platform that's just 3"x5" and costs around
$100. The power figures are still not in. It will soon be an open
platform for other researchers, and it will allow us to explore the
range of architectural tradeoffs necessary to realize pervasive SDR
systems.
Talking Book. ICT has the potential for deep social impact in
developing regions but today's typical devices - laptops, mobile
phones, and similar systems - are often still too expensive for many
scenarios. The thesis of this work is that custom ICs can enable a new
tier of low-cost information access devices with a price point that
will make them widely accessible. And, with control over the silicon,
these systems can economically address many other challenges. To
evaluate these ideas, we focus on a deceptively simple problem -
low-cost information access for illiterate populations through audio
recordings - and explore how custom silicon allows us to reduce cost,
lower power, leverage conventional infrastructure in unconventional
ways, and optimize the interface for usability. In particular, we
explore how a rural audio computer can be designed around just three
chips, use an inexpensive capacitive touch interface, employ inductive
communications for peer-to-peer data transfer, and employ content
download over GSM voice and FM broadcast as two wide area options. The
resulting design point – enabled by aggressive silicon integration –
affords a device that can be built for less than $10. We are working
with Literacy Bridge, a
Washington state non-profit, to initially bring this technology to
improve child and maternal health for 25,000 people across Ghana.
