Researchers from China’s College of Engineering and Applied Sciences at Nanjing University have developed an innovative alternating-current electroluminescent (ACEL) display that is thin enough to be worn on skin, similar to a temporary tattoo. It links with a human-machine interface that enables information to be displayed directly onto human skin. It consists of an electroluminescent layer made of light-emitting microparticles sandwiched between two flexible silver nanowire electrodes. Read more for additional pictures and information.
It uses the ceramic nanoparticles embedded in the stretchable polymer to make the ACEL display brighter than any other, allowing one to clearly view it even in a brightly-lit room. In other words, you can use it as a low-voltage stopwatch since the device doesn’t produce any detectable electricity.
These so-called epidermal sensor may allow the continuous monitoring of heart rate, blood pressure, blood oxygen levels, and even glucose. The display will provide visual information of these metrics. These metrics are very important for athlete training and biomedical areas. You may see some of these demonstrations in the near future,” said Professor Desheng Kong.
