Yeah, I'm one who fears the "Big Brother" syndrome, but this is kind of cool nonetheless.
Scientists have developed the "EES" or electronic epidermal system, which is a computer chip that attaches under the skin and tracks the movements of the body. It flexes naturally with the skin and appears almost like a barcode tattoo. It can bend, twist, expand, and contract, and none of this will affect the integrity of the chip.
Okay, so what's the use?
According to: This Website:
"Our paper demonstrates our ability to monitor ECG (as a monitor of heart disease and metabolism), EMG (as a measure of, among other things, gait during walking) and EEG (as a measure of cognitive state and awareness).
We have also shown that these same devices can stimulate muscle tissue to induce contractions. When combined with sensing/monitoring, such modes of use could be valuable in physical rehabilitation. We also have interest in sleep monitoring (for sleep apnea), and neo-natal care (monitoring premature babies, in particular)."
I encourage you to read that entire article. When used properly, this will be an extensive medical breakthrough.
