One of the clever features of the technology is that it does not need to be calibrated against a blood pressure cuff. These researchers have achieved just that, with individual units potentially costing only pennies. Developing low-cost solutions is crucial for such patients. However, for those who live far away from a medical clinic, or who don’t have access to reliable diagnostic technology, tracking their blood pressure is haphazard. With mass production, the researchers claim that the clip could cost just 10 cents to make.īlood pressure measurements are crucial to ensure good health over our lifetime. At present, the clip costs only 80 cents to produce, providing a low-cost method for people in low-resource areas to monitor their blood pressure. A smartphone app then uses algorithms to interpret these data and estimate the blood pressure. The user presses their finger against the clip, and the system can infer the amount of blood passing through the finger, and the amount of pressure being exerted on the clip by the finger. The device is a clip that attaches over a smartphone camera and flash. Engineers at the University of California San Diego have developed a low-cost cuffless blood pressure monitor.
