Pulse waves—changes in a blood vessel’s volume brought on by the heart pumping blood—are measured by an optical heart rate sensor. An optical sensor and green LED are used to measure the volume change in order to identify pulse waves.
The Global Optical Sensor for Heart Rate Monitor market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Recently, ROHM announced the availability of an optical heart rate sensor designed specifically for wearable gadgets like sports bands and smartwatches.
In order to increase sensitivity and enable accurate pulse wave detection even with low LED brightness, the BH1790GLC makes use of patented analogue circuit technology and optical sensor know-how. This results in a class-leading low power consumption.
In order to create an optical sensor for heart rate monitoring that is tailored for wearables and satisfies market demands for low battery consumption and high accuracy, ROHM draws on optical sensor development expertise and IR elimination technologies developed over a number of years.
High accuracy detection is made possible by a sophisticated optical filter, which also increases battery life and 10x lessens the impact of IR rays compared to standard devices.
