All Foreigners Should Pay Attention – Important News for Those With Resident Permits in Saudi Arabia

Headphones and earphones used around the world are only used to hear sound. However, now with the addition of a chip they can be turned into a very useful sensor.

Rutgers University engineers have developed a very low-cost, easy-to-use chip that senses headphones and can be read on a smartphone. Although the sensor is large at the moment, it can be made more sensitive and smaller, which is being worked on. This invention has been dubbed ‘Headfee’.

In this way, millions of headphones used around the world can be converted into functional sensors. With the addition of such a chip, headphones can be used for heart rate measurements, gyroscopes, accelerometers, microphones and other devices.

The invention used headphones ranging from تین 3 to ہزار 15,000. HeadFi then accurately identified the user from 97 to 99.5. Successfully noted 96 to 99 percent of healthy heart rate counts and 99 percent of successful movements.

Although it is still in its infancy, the chip could revolutionize the world because headphones are everywhere and heart patients are no less.
