What I’m doing
Jeeva
Jeeva is bringing a radically different type of wireless connectivity solution into the mainstream. Cheaper, lower power, and even battery-less connectivity are all possible. I’m a co-founder and COO of Jeeva.
What I did
Ambient Backscatter
In graduate school, I was part of a team that developed technologies to allow devices to talk by reflecting ambient radio signals. This is maybe the latest incarnation of Harry Stockman’s 1948 dream of using reflections to communicate.
Ambient RF Energy Harvesting
The built environment is full of radio frequency energy from sources such as cell towers, broadcast television transmitters, and WiFi access points. I’ve helped to create new systems for harvesting and combining the ambient energy from all these sources.
WISP
The WISP is an open-source, software-defined RFID tag built around a low-power MSP430 microcontroller. It’s powered wirelessly, and so doesn’t have or need a battery. The WISP is a long-running project of my PhD advisor, Prof. Joshua Smith, and I was lucky enough to be involved in the development and promotion of the WISP 5.
