Researchers at the University of Illinois have created a minute wireless patch which can adhere to the skin to monitor a patient’s vital signs such as temperature and heart rate.
The device had been likened to a ‘temporary tattoo’ in the way it is worn on the skin, and eliminates the bulky wiring and electrodes used in current monitors to ensure patients are more comfortable.
The researchers embedded electronic sensors in a film thinner than the diameter of a human hair, which was placed on a polyester backing like those used for the temporary tattoos. The result was a sensor that was flexible enough to move with the skin and would stick without the use of adhesives. During the experiment, the devices had remained in place for up to 24 hours, although researchers assert this could last as long as two weeks.
The monitor resembles a bandage and contains an antenna that could be used to transmit data though a radio. As opposed to adhesives, the monitor relies on a weak force that causes molecules and surfaces to stick together without interfering with motion, although use of other substances may be considered for longer-term use. The current design has a small coil and could be powered through induction placing it near to an electrical coil. This would permit intermittent use, and for longer-term monitoring a tiny battery or storage capacitor could be fitted.
John A. Rogers, a researcher at the University of Illinois states that their ultimate goal was to reshape electronics so they were more in line with the human body.”’The goal is really to blur the distinction between electronics and biological tissue” he said.
In addition to monitoring patients in hospitals, other uses for the devices could include monitoring brain waves, muscle movement, sensing the larynx for speech and emitting heat to help heal wounds. In addition, with further development, the devices could potentially be made touch sensitive and placed on artificial limbs.
It is hoped that the device will help to fulfil the requirement for equipment to be more convenient and less stressful for patients, ultimately permitting accurate and more reliable monitoring.
