Temporary electronic tattoos could soon help people fly drones with only thought and talk seemingly telepathically without speech over smartphones, researchers say.
Commanding machines using the brain is no longer the stuff of science fiction. In recent years, brain implants have enabled people to control robotics using only their minds, raising the prospect that one day patients could overcome disabilities using bionic limbs or mechanical exoskeletons.
But brain implants are invasive technologies, probably of use only to people in medical need of them. Instead, electrical engineer Todd Coleman at the University of California at San Diego is devising noninvasive means of controlling machines via the mind, techniques virtually everyone might be able to use.
His team is developing wireless flexible electronics one can apply on the forehead just like temporary tattoos to read brain activity.
“We want something we can use in the coffee shop to have fun,” Coleman says.
