 BP Clip is a new technology that enables a smartphone to measure blood pressure without the need for a bulky and expensive blood pressure cuff. Instead, it uses a simple plastic clip with a spring-loaded mechanism to capture the pressure applied to the user's finger. This information is then used by the phone's camera to calculate the user's blood pressure. The system has been shown to have a high degree of accuracy when compared to traditional blood pressure cuffs, making it ideal for use in home health care applications.
