A thermoelectric generator (TEG) can harvest energy from the temperature differences between the soil surface and shallow ground. When tested in April in Oklahoma, the TEG generates 10~40 mV of stable DC voltage. Bluetooth Low Energy (BLE) protocol can be used to send data. The relationship between the duty cycle and system power consumption was explored. Moisture & humidity sensors were also implemented.

A flyback ("Boost") converter was designed and tested using a commercial off-the-shelf IC (MCRY12) and 1:50 transformer. It can boost up to 1V of DC voltage when the TEG input voltage is around 20 mV. The Boost converter PCB measures about 0.5 square inches (or 2 cm²), compact enough to be integrated with the TEG and the copper rod.

2021 Kicker Design Competition
2021 Kicker Design Competition
ECEN 5363 (Mixed-Signal IC Design) and ECEN 3714 (Network Analysis) held a joint student design contest in Fall 2021. The winners are:
Best Design: "A Dynamic Bias Comparator Design and Layout with Performance Simulations" by Fahim Hossain, Sam Fellwock.
People's Choice: "Side-Channel Attack with ChipWhisperer" by Christian Moser.
The contest was sponsored and judged by Kicker, a high-performance audio company headquartered in Stillwater, OK.
Here is a graduate student presentation during ECEN 5363: Mixed-Signal IC Design.
