watch: new tattoo-like skin device to monitor your health - skin care device

The thin device does not require any battery work and can detect changes in skin temperature, sun exposure, heart rate, skin tone and blood oxygen levels.
Scientists have developed a new tattoo.
Like a monitoring device, it can be fixed on the skin like a patch, and it can detect changes in skin temperature, sun exposure, heart rate, skin tone and blood oxygen level. The tiny ultra-
No battery is needed for thin equipment to work.
It captures a small amount of energy from a smartphone or tablet that takes advantage of the near
Field Communication (NFC).
NFC is a technology that uses induction between antennas inside a portable device.
Researchers such as John Rogers of the University of Illinois in the United States say radio frequencies are used to send messages that can be used as energy, making it unnecessary to use batteries.
According to techxplore, this device, which is not thick with stickers, is flexible, affixed to the skin and collects information about the body, which is then wirelessly transmitted to nearby devices.

In terms of skin.
The reflected light was used to measure changes in heart rate, skin tone and oxygen levels, the researchers said.
The device also has dyes-
The light sensor that measures ultraviolet rays and another sensor that monitors the temperature of the skin.
According to the researchers, this device is useful for health --
Medical facilities will eventually benefit the general public.
The findings are published in the journal scientific progress.
