Products for personal healthcare
Our optical semiconductor devices are used in numerous fields, ranging from industrial equipment to consumer devices. Especially, they attract the medical and healthcare fields as key components of healthcare products for personal and company use.
Due to high health-consciousness, the demand for personal healthcare products is increasing. It is obviously helpful for preventative medicine if we can see any changes in our physical condition day by day by ourselves. Also, It can prevent dehydration and heat stroke by detailed phyical condition and exercise intensity monitoring during physical exercise, and is also helpful for planned training management.
These days, wrist watch type terminals are sold, which use light to irradiate blood vesseles from changes in the amount of reflected light. They have a function 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.
Our optical semiconductor devices contribute to the development of wearable devices revolutionize the approach to healthcare. We also play 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.
