A flexible, wearable synaptic transistor created by Penn State engineers may soon make robotics and wearable technology a little smarter. In order to strengthen and weaken the gadget's memory, the device functions like neurons in the brain by sending signals to some cells while inhibiting others. Led by Cunjiang Yu, Dorothy Quiggle Career Development Associate Professor of Engineering Science and Mechanics, and associate professor of biomedical engineering and of materials science and engineering, the team designed the synaptic transistor to be integrated in robots or wearables and use artificial intelligence to optimize functions. “Mirroring the human brain, robots, and wearable
