Purdue Develops Low-Cost, Easy-to-Use Hydrogel Sensor

Despite its simple design, the sensor is highly-sensitive and precise.

Cagri Savran, study leader and an associate professor of mechanical engineering at Purdue University, along with Babak Ziaie, a Purdue University professor of electrical and computer engineering and biomedical engineering, and a team of researchers, are developing a low-cost, highly-sensitive biological and chemical sensor that can detect changes in the pH level of an environment without needing several moving parts.
