Researchers have created a wearable device that is as thin as a temporary tattoo and can store and transmit data about a person’s movements, receive diagnostic information and release drugs into skin. Similar efforts to develop ‘electronic skin’ abound, but the device is the first that can store information and also deliver medicine — combining patient treatment and monitoring. Its creators, who report their findings today in Nature Nanotechnology1, say that the technology could one day aid patients with movement disorders such as Parkinson’s disease or epilepsy.
Wearable electronics that mimic skin, both mechanically and in its sensing properties, will be a vital part of the future technologies that will be integrated into our everyday lives. This ‘electronic skin’ (e-skin) will need to be as robust and durable as normal human skin to withstand repeated use and mechanical damage.
Motion, an act we take for granted until it is stolen by disease, age or injury, can now be measured by a growing array of portable electronic devices for consumer and medical use. Whether for fun, fitness or medicine, these simple wearable devices rely on tiny accelerometers that capture only the gross motion of a limb or entire body.
(Nanowerk News) Every year, an estimated half-million Americans undergo surgery to have a stent prop open a coronary artery narrowed by plaque. But sometimes the mesh tubes get clogged. Scientists report in the journal ACS Nano (“Bioresorbable Electronic Stent Integrated with Therapeutic Nanoparticles for Endovascular Diseases”) a new kind of multi-tasking stent that could minimize the risks associated with the procedure. It can sense blood flow and temperature, store and transmit the information for analysis and can be absorbed by the body after it finishes its job.
