Researchers devise new, stretchable antenna for wearable health monitoring
Date:3/18/2014

Researchers from North Carolina State University have developed a new, stretchable antenna that can be incorporated into wearable technologies, such as health monitoring devices.

"Many researchers including our lab have developed prototype sensors for wearable health systems, but there was a clear need to develop antennas that can be easily incorporated into those systems to transmit data from the sensors, so that patients can be monitored or diagnosed," says Dr. Yong Zhu, an associate professor of mechanical and aerospace engineering at NC State and senior author of a paper describing the work.

The researchers wanted to develop an antenna that could be stretched, rolled or twisted and always return to its original shape, because wearable systems can be subject to a variety of stresses as patients move around.

To create an appropriately resilient, effective antenna, the researchers used a stencil to apply silver nanowires in a specific pattern and then poured a liquid polymer over the nanowires. When the polymer sets, it forms an elastic composite material that has the nanowires embedded in the desired pattern.

This patterned material forms the radiating element of a microstrip patch antenna. By manipulating the shape and dimensions of the radiating element, the researchers can control the frequency at which the antenna sends and receives signals. The radiating layer is then bonded to a "ground" layer, which is made of the same composite, except it has a continuous layer of silver nanowires embedded.

The researchers also learned that, while the antenna's frequency does change as it is stretched (since that changes its dimensions), the frequency stays within a defined bandwidth. "This means it will still communicate effectively with remote equipment while being stretched," Adams says. "In addition, it returns to its original shape and continues to work even after it has been significantly deformed, bent, twisted
