An inexpensive plastic fingertip clip and custom smartphone app developed by University of California, San Diego researchers works with a smartphone's camera and flash to measure the user's blood pressure.

The goal is to make blood pressure monitoring more affordable and accessible.

The clip, which is placed over the smartphone's camera and flash, does not have to be calibrated to a cuff.

The smartphone app can measure the amount of pressure applied by the fingertip and the volume of blood moving in and out of the fingertip; it then converts this data into systolic and diastolic blood pressure readings using an algorithm.
