A Chronically Implanted, Continuous Ph Monitoring System For Rats, Ryan B. Budde, Pedro P. Irazoqui

The Summer Undergraduate Research Fellowship (SURF) Symposium

Many body systems operate within a strict pH range, and any deviation can cause harm. pH measurement systems are used in many biomedical research fields. Measurement systems have been able to continuously record pH for a short period of time wirelessly, or over a long period of time with wires, but no system is currently capable of long term, wireless, continuous pH recording. This paper proposes a new pH measurement system that is capable of such measurement. The system is composed of inexpensive, micro-scale, and easy to manufacture pH sensitive and reference electrodes and a data acquisition and transmission module …
