Electronic tattoo monitoring device

Scientists at the University of Illinois have recently launched a "tattoo", which is essentially an electronic device capable of monitoring a patient's illness after leaving the hospital.

Usually when doctors want to know the patient's condition, such as the heartbeat or brain activity, they have to use bulky machines and attach the electrodes to the skin with sticky gel, which forces patients to limit Moving and sometimes irritating the skin.

John Rogers at the University of Illinois and his colleagues have conducted research and development "Electronic equipment epidermis" flexibility and high elasticity helps doctors can monitor the health status of patients while they still living normally.

Electronic equipment consists of a circuit board containing very small strands of transistors, diodes and resistors made of silicon and gallium arsenide. The circuit is placed on a thin rubber sheet and a transparent plastic sheet is water soluble. The device can be stretched or shortened to match the movement of the muscles in the body. They can detect changes in electronic signals when skin and muscle move. These signals are then processed by the computer and give information about the condition of the patient.

Current patches are used to monitor electrical signals, brain activity, and muscles. Scientists hope in the future that this "fashionable" health monitor may stimulate shrinkage, though this has been reported in mice, but has not yet been officially announced.
