Renewable energy can enable diverse self-sustainable cyber-physical
systems with applications ranging from healthcare to off-grid home
energy management. However, there are several challenges that need to
be addressed before such systems can be realized. For instance, how do
we balance the small and often variable energy budgets imposed by
renewables with system functionality? How can we design sensitive
physical sensors and efficient harvesting circuits for mW energy
sources such as sound and indoor light? For systems such as off-grid
homes that interact with humans, how do we balance demand and supply
while being cognizant to usability needs?

In this talk, I will present techniques that address these
challenges. Specifically, I will propose a Hierarchical Power
Management paradigm that combines platforms with varied energy needs
to balance energy consumption and functionality, the design of an
efficient harvester for sound scavenging, and sensitive ECG sensors. I
will also present a measurement study that reveals the energy
management challenges faced by off-grid home residents. Finally, I
will conclude with the design of a solar replayer platform that allows
immense flexibility in evaluating solar panel driven systems, and
works for a wide range of panels.
