Helping to create the next generation of smart wearables.
I joined the UCSD Nanobioelectronics Laboratory in early 2023. In that time, I’ve helped develop some groundbreaking devices that meld advanced biosensors with ultra low-power embedded circuits and human-powered energy harvesters. My first project with the team is a device I call the “MC-You” system: an embedded Nordic processor, Bluetooth antenna, four biosensor ports, and a combination battery/ energy harvester that uses human sweat to produce power. This device was made with a flexible PCB (to be worn on a finger) and is roughly the size of a thumbnail.

The fully-integrated MC-You with biosensors, batteries, and energy harvester. It wraps around your finger, sending vitals to a companion mobile application over Bluetooth and powering itself partly through sweat.

This is what the MC-You board looks like when it arrives from the assembly plant. The additional size on the flex PCB is for adequate registration in their pick-and-place machine.

Here is a render of the final version of the MC-You board before going to production.

This is a render of the back side of the MC-You board, showing it's JLINK programming pins. To save size, this board requires an external JLINK programmer to be programmed.

This is a block diagram of the entire MC-You system I designed.
