SuperUROP Project

Low Energy Radio for Vital Signs Transmission for the Ear to the Smart Phone
Faculty Advisor: Charles G. Sodini

This project will modify and improve a prototype of an ear-worn device that is used to measure and transmit ECG, BCG, and PPG data of an individual. The current prototype of the device uses a proprietary 2.4GHz RF transceiver to send data wirelessly. The goal of the project is to use a Bluetooth Low Energy (BLE) transceiver in place of the current transceiver. By using the BLE technology, we aim at transmitting at a higher data rate and with reduced power consumption.
The majority of the work will be done in the lab facilities of 38-265. The project begins by identifying and studying BLE transceiver chips currently available on the market. The student will then select the chips that are more appropriate for our application and test them. Testing the devices involves checking for accurate data transmission, as well as measuring and comparing power consumptions and transmission ranges of the systems. The second part of the project is the design of a PCB on which the test chips will be populated along with peripheral components. Finally, the designed PCBs will be tested for proper data transmission, power consumption, and range in a clinical setting.
