It works as an alert system .. Adhesive card on the skin to measure pulse and self

Researchers in the United States have designed a new device that uses a wearable technology called BodyNet, which measures the physiological signals emitted from the skin.

Stanford engineers have developed a new type of wearable technology consisting of wireless sensors that stick like price tags to the skin.

Zhenan Bo-hee, a professor of chemical engineering at Stanford University, says she believes wearable technology will one day be used in medical settings to take full body readings.

Light and efficient technology
The work on the sensors took three years, with the ultimate goal being to develop a technique that would be comfortable to wear with no electrical circuits preventing the stickers from stretching with the skin.

To achieve this, the team used a variety of RFID technology.

When the card is attached to the body, there is a clothing-installed receiver that transmits and receives radio waves from the card, transmitting energy to charge the card and receiving information about a person's physiological indicators.

So the researchers had to deal with one of the obstacles, where they needed an antenna that could stretch and bend like the skin.

To overcome this obstacle, they printed metallic ink on a rubber label, yet the signal was weak and unstable, and they did not benefit from it.

To overcome this problem, researchers at Stanford University have developed a new type of radio-frequency identification system that can transmit strong and accurate signals to the receiver despite constant fluctuations.

The battery-powered receiver uses Bluetooth technology to periodically upload data from labels to a smartphone, computer or other permanent storage system, according to a Stanford University press release.

Currently, the labels produce readings about breathing and pulse, but the team hopes to incorporate race, temperature and other sensors into their antenna systems.
