Brad graduated from the University of Missouri with a Bachelor's degree in Electrical and Computer Engineering in 2008. After graduation he served four years in the United States Marine Corps as a communication officer before returning to graduate school. He joined the Berkeley Sensor and Actuator Center in September 2013 and is a member of Prof. Kris Pister's group working on wireless integrated circuit design for the Single Chip Mote.
Single Chip Mote [BPN803]
To exploit the true potential of ubiquitous connectivity at scale, wireless nodes in
a sensor network need to have a long lifetime and low cost. To reduce the cost of a sensor
node, complete system integration is needed, including communication, computation, sensing, and
power management on a single integrated circuit with zero external components. Therefore, a
Single Chip Mote sensor node is being developed that is intended to operate from harvested
energy stored in an integrated printed battery. Low-power wireless communication plays a key
role in extending the lifetime of a wireless sensor due to high active power consumption of
the radio in comparison to the rest of the node. Traditional transceiver architectures also
require off-chip components such as crystal oscillators and passives, which must be eliminated
in order to enable a completely monolithic solution. The elimination of external components,
combined with reduction in transceiver power consumption, will truly enable perpetual operation
of wireless nodes at low-cost and hence realize the vision of ubiquitous connectivity at scale.
