Optical Sensor Measures Blood Pressure, Stress, Vascular Age

ROHM latest optical heart rate sensor for smart bands and watches is capable of measuring blood pressure, stress, and vascular age at a 1,024-Hz sampling rate. The BH1792GLC, the company’s second generation optical heart rate sensor, features a power consumption of 0.44 mA (during heart rate measurement), allegedly the lowest in the industry. And the 1024Hz sampling rate makes it possible to measure heart rate up to 32 times faster than conventional solutions while also supporting vital sign sensing such as vascular age and stress measurement demanded by the latest wearable and fitness devices.

 

A heart rate sensor evaluation board (BH1792GLC-EVK-001) for use with ROHM sensor shields that connect to open platform MCU boards (e.g. Arduino Uno) is also available. The BH1792GLC is available now, priced at $5.30 each/1,000 and the BH1792GLC-EVK-001 costs $23.81 each. Datasheets are available for the BH1792GLC and BH1792GLC-EVK-001.
