Smartphone Case Measures Blood Pressure

Mar-13-18 A prototype smartphone case aims to measure blood pressure as accurately and quickly as traditional arm cuffs.

Developed by a team at Michigan State University, the phone case is equipped with a sensor unit made up of a force sensor with an optical sensor on top. Following prompts from the companion app, the user holds the case at heart level and places their finger on the sensor, where the system measures the systolic and diastolic blood pressure and displays the results on the smartphone.

Currently, the readings are comparable in accuracy to a finger cuff, and the team hopes to improve that accuracy while also developing a smaller system that can be integrated into standard smartphone cases.
