Researchers at the National University of Singapore have developed a material that is used as inserts for clothing and can significantly increase the autonomy of wearable electronics. Thanks to the invention, wireless devices such as headphones or smartwatches are able to work much longer, and the signal transmitted from the gadgets will be amplified 1000 times.
Currently, almost all wearable accessories are connected to smartphones via Bluetooth or Wi-Fi. They emit radio signals in all directions, which means that most of the charge is wasted. Savings are due to the reduction of radiation in the surrounding space. In other words, to maintain stable pairing wearable accessories do not need a constant strong signal, as represented by scientists antenna of metamaterials amplifies it 1000 times. This saves the charge of headphones or smartwatches, and all the waves coming from Wi-Fi and Bluetooth modules receive a secure and reliable connection with a directional signal. In this case, the action of such an amplifier is terminated at a distance of 10 centimeters from the human body, which provides an additional degree of data protection.
The developers believe that their material can be used to monitor the health status and remove the physiological parameters of athletes or patients in hospitals. Manufactured inserts serve as waveguides. They are not afraid of washing, drying or Ironing, and the production of such material was very economical.
