(Original title: Japanese Kyocera Corp. will integrate health sensors into headphones) Japanese electronics maker Kyocera also seems to be opening up a new fitness tracker market. According to Nikkei, the company recently introduced a new tiny optical sensor for measuring blood flow in subcutaneous tissues. This new sensor uses a laser Doppler velocimeter (LDV) to measure the amount of blood under the skin. The LDV measures the velocity of the fluid by using a "Doppler shift" in the laser beam. By analyzing the information and recording a series of details about the health of the body. Kyocera's sensors can detect blood pressure and blood moisture, which can determine whether the wearer has signs of heat stroke. Kyocera's sensor has a size of 3.2 x 1.6 x 0.9mm and offers high sensitivity and reliability. This means that this sensor can be installed in the headset, and most of the current health sensor devices are worn on the wrist, such as Apple watch, millet bracelet and so on. Kyocera Corp. also demonstrated its earphone prototype with optical sensors at the 2017 Medtec conference in Japan last month. Because the sensors are suitable for the internal structure of the ear, the company has seen many potential uses, such as more accurate monitoring of sleep. Data, combined with music and heart rate also understand the tension of the wearer and carry out other functional content. At present, this sensor is still in the prototype device. Perhaps one day we will have the opportunity to see the headset product with built-in fitness tracker so that the data tracking can be done by listening to a piece of music. 燑br>
