Until now, accurate blood-pressure monitoring could only be achieved with bulky and mechanical cuff-based medical devices. Now, Maxim Integrated Products, Inc. has introduced a solid-state blood-pressure monitoring solution to more conveniently track this critical health indicator.
Design engineers can develop blood-pressure trending solutions with the MAXREFDES220# reference design from Maxim. Comprised of a complete integrated optical sensor module, a microcontroller sensor hub and a sensing algorithm, the MAXREFDES220# optical blood-pressure trending solution can be embedded into smartphones or wearables. It enables users to place their finger on a device for 30-45 seconds while resting to measure blood pressure anywhere and anytime. The reference design includes the MAX30101 or MAX30102 high-sensitivity optical sensor, as well as the MAX32664D sensor hub IC with built-in algorithms (more info).
