Wearable AC

University of Missouri engineers design on-skin electronic device providing a personal air conditioner without needing electricity

One day, soldiers could cool down on the military battlefield -- preventing heat stroke or exhaustion -- by using "wearable air conditioning," an on-skin device designed by engineers at the University of Missouri.


An on-skin device designed by engineers at the University of Missouri can achieve around 11 degrees Fahrenheit of cooling to the human body. The device also includes numerous human health care applications such as the ability to monitor blood pressure, electrical activity of the heart and the level of skin hydration.

The device includes numerous human health care applications such as the ability to monitor blood pressure, electrical activity of the heart and the level of skin hydration.

The findings are detailed in the journal Proceedings of the National Academy of Sciences.

Unlike similar products in use today or other related concepts, this breathable and waterproof device can deliver personal air conditioning to a human body through a process called passive cooling. Passive cooling does not utilize electricity, such as a fan or pump, which researchers believe allows for minimal discomfort to the user.

"Our device can reflect sunlight away from the human body to minimize heat absorption, while simultaneously allowing the body to dissipate body heat, thereby allowing us to achieve around 11 degrees Fahrenheit of cooling to the human body during the daytime hours," said corresponding author Zheng Yan, an assistant professor in the College of Engineering. "We believe this is one of the first demonstrations of this capability in the emerging field of on-skin electronics."

Currently, the device is a small wired patch, and researchers say it will take one to two years to design a wireless version. They also hope to one day take their technology and apply it to 'smart' clothing.

"Eventually, we would like to take this technology and apply it to the development of smart textiles," Yan said. "That would allow for the device's cooling capabilities to be delivered across the whole body. Right now, the cooling is only concentrated in a specific area where the patch is located. We believe this could potentially help reduce electricity usage and also help with global warming."

Im Focus: ScanCut project completed: laser cutting enables more intricate plug connector designs

Scientists at the Fraunhofer Institute for Laser Technology ILT have come up with a striking new addition to contact stamping technologies in the ERDF research project ScanCut. In collaboration with industry partners from North Rhine-Westphalia, the Aachen-based team of researchers developed a hybrid manufacturing process for the laser cutting of thin-walled metal strips. This new process makes it possible to fabricate even the tiniest details of contact parts in an eco-friendly, high-precision and efficient manner.

Plug connectors are tiny and, at first glance, unremarkable – yet modern vehicles would be unable to function without them. Several thousand plug connectors...
