ROHM developed a pulse sensor "BH1790GLC" for measuring pulse signals

ROHM, a world-renowned semiconductor manufacturer, has developed a pulse sensor "BH1790GLC" for measuring pulse signals for wearable devices such as sports bracelets and smart watches.

"BH1790GLC" uses ROHM's accumulated experience in optical sensor technology and unique analog circuit technology to improve sensor sensitivity. Thus, even if the brightness of the LED is low, the pulse can be accurately sensed, achieving the industry's smallest level of low power consumption.

In addition, the "BH1790GLC" uses a pulse filter-specific optical filter structure to detect pulse signals with high precision. Therefore, not only does the wearable device have a longer battery life, but also reduces the influence of infrared rays to less than one-tenth of that of conventional products, and high-quality pulse can be obtained even in a strong infrared environment such as strenuous exercise and outdoor. Signals help drive the further development of wearable devices.

In the future, ROHM will continue to develop products that contribute to a safe and comfortable society in the field of wearable devices that are becoming more and more popular.

<Background>

In recent years, the demand for energy saving and miniaturization of electronic equipment has become higher and higher. Among them, wearable devices such as sports bracelets and smart watches have become mainstream trends, and it is expected that there will be further significant growth in the future. However, wearable devices have an increasing demand for low-power components that can be driven for a long time due to the problem of battery capacity limitations. In response to this demand, ROHM has successfully developed a pulse sensor that is very suitable for wearable devices by utilizing years of experience in optical sensor development and unique infrared removal technology. Meet the needs of society by developing low-power and high-precision sensors.
