Team's E-Whiskers May Be a Touchstone for Future of Electronic Skin

University of Texas at Dallas (UT Dallas) scientists have developed electronic sensors modeled after whiskers from shape-memory polymers.

UT Dallas' Jonathan Reeder and Walter Voit say these e-whiskers are a significant step toward the creation of electronic human skin.

One type of e-whisker was cut out from a sheet of the polymer, which becomes flexible in response to heat; an elastic strain sensor was patterned on top of each whisker, and blowing hot air through the bottom of the cutouts made the material bendable.

Once the e-whiskers were built, disruptions triggered changes in the strain sensor, enabling accurate tracking of each e-whisker's position.

"Our e-whiskers were able to detect force, pressure, proximity, temperature, stiffness, and topography," Voit says. "As they brush up against—or whisk across—various materials, they mimic the sensing capabilities of human skin."
