My current research is focused on wireless power delivery across several orders of magnitude, from charging cellphones and tablets to powering small, low-power sensor nodes. The main challenge in wireless power transmission is to maintain reasonable efficiency while being moderately flexible in the number of receivers, and their distance from and alignment with respect to the transmitter.
The work I did for my Master's thesis was focused on delivering low-cost, ubiquitous health monitoring and personal computing solutions. More specifically, I worked on a Body Area Network that can serve a heterogeneous group of sensor nodes around the body using e-textiles. We designed a single network that could simultaneously transmit power to and communicate (in either direction) with a sensor node. We integrated the circuits for power and data transfer with a custom-designed Medium-Access and Control (MAC) protocol on a single chip.
I have previously worked on board-level interconnects that use novel termination schemes to achieve transmitter output termination with significant power savings compared to traditional ways of doing the same. I have worked on designing efficient energy harvesters during my internship at TI and on channel diversity analyses as part of the 802.11ac standardization effort during my internship at Qualcomm.
