Wearable body sensors have one problem: they need energy and antennas, and all this creates
The antenna caused the most problems. To create it, you need only a little metal on a silicone basis, but the signals of such an antenna usually weaken, since our body is always in motion. Scientists had to develop the latest RFID system, which can reliably send a signal despite constant changes.
The receiver itself is quite large and uses Bluetooth to transfer information to a smartphone or PC.
But now, BodyNet is seriously limited.the necessary proximity between the sticker and the receiver. This is not a problem with initially planned studies, such as measuring your heart rate or studying sleep disorders, but in conditions of physical activity, where you can’t count on the ideal position of the sensor, BodyNet can save. But the team solves this problem by trying to place the antennas directly in the clothes.
Moreover, scientists have far-reaching plans. Researchers are already working on a sensor that can receive information about body temperature and stress levels from sweat. They hope someday to create a device that can remotely collect data about the entire body. This can seriously improve the lives of people with poor health, as well as help athletes in training, without limiting their movement.
