Biomedical Sensor Board

Project number: 
UA Department of Biomedical Engineering
Academic year: 
The team is tasked to build a biomedical sensor board that will fit as extension (HAT) onto the Raspberry Pi 3 or 4. The sensor board shall measure:
1. Skin Impedance
2. Electrocardiogram
3. Blood Oxygenation
4. Sound
5. Temperature in non-contact and contact mode

Software developed in Python shall visualize the signals. Electrical safety will need to be considered.

This board will be utilized in undergraduate education. Each sensor unit shall be well documented and include a description of the measurement principle and physiologic origin of the signal. Current state of the art components shall be selected. Commonly used clinical sensor shall be interfaced with the sensor board. The cost of the system shall not exceed the typical university laboratory course fee.

Each team member shall be responsible for the system design of at least one of the measured signals. At least one team member shall be responsible for the integration of the subsystems and interface to the Raspberry Pi. Each team member shall develop basic software illustrating the operation of their subsystem.
To complete this project, students will need to have knowledge of basic printed circuit board design and SMD soldering. Students not having PCB design or soldering experience will need to pass sponsor provided training during the first quarter of the fall semester.
