Optical semiconductor devices for personal healthcare.

NJR's optical semiconductor devices are used in numerous fields, ranging from industrial equipment to consumer devices. However, they are attracting especial attention in the medical and healthcare fields as key components of healthcare products for personal and company use.

Contribution for personal healthcare by optical semiconductor devices.

The demand for personal healthcare products is increasing from high health-conscious. It is obviously helpful, for preventative medicine, if we can see for ourselves any changes in our physical condition day by day. And also, It can prevent dehydration and heat stroke by detailed phyical condition and exercise intensity monitoring during physical exercise and also helpful to planned traning management.

Recentry, wrist watch type terminal is saled that uses light to irradiate blood vesseles from changes in the amount of reflected light, it have functoin to be able to show the increase-decrease of pulse rate and amount of oxygen in the blood (SpO2: peripheral capillary oxygen saturation). As diagnosis for severity of pneumonia by COVID-19, SpO2 monitoring is said to be useful.

NJR's optical semiconductor devices are contributing to the development of wearable devices that are revolutionizing our approach to healthcare. NJR is also playing a part in the development of various new products - such as smartphones that can detect your pulse and SpO2 from your fingertip, and earphones that can monitor your health while you listen to music.
