![]() Neurons process and transmit information by releasing neurotransmitters at their synapses, typically located at the neural cell ends. The same results will be possible for devices that use the synaptic transistor, as the artificial intelligence is able to ‘learn’ and adapt to its environment.”Īccording to Yu, the artificial neurons in the device were designed to perform like neurons in the ventral tegmental area, a tiny segment of the human brain located in the uppermost part of the brain stem. “For example, if we burn our hand on a stove, it hurts, and we know to avoid touching it next time. “Mirroring the human brain, robots and wearable devices using the synaptic transistor can use its artificial neurons to ‘learn’ and adapt their behaviors,” Yu said. ![]() 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. The device works like neurons in the brain to send signals to some cells and inhibit others in order to enhance and weaken the devices’ memories. Robotics and wearable devices might soon get a little smarter with the addition of a stretchy, wearable synaptic transistor developed by Penn State engineers. view moreĬredit: Credit: Kelby Hochreither/Penn State Conventional transistors, on the other hand, are rigid and can break after being bent. In the picture below, the leads I am connecting to my external source are the ones labeled “to 5V” and “to GND”, and I am using the capacitor as well.Image: The synaptic transistor is reconfigurable, meaning it can be twisted and bent, yet still remain functional, as researchers Cunjiang Yu (left), Dorothy Quiggle Career Development Associate Professor of Engineering Science and Mechanics (ESM), and ESM graduate student Hyunseok Shim demonstrate in this photo. (picture of my little wiring diagram included, as well as the very simple test sketch I have been using to try to debug this problem) Why will my transistor and circuit pass the Arduino’s power through, but not my external source? I have also swapped transistors just in case the first one was acting funny… no dice. ![]() I also noticed that the little wiring diagram I was using had emitter and collector mixed up, so I fixed that in the circuit. I checked the data sheet for the PN2222A, and 6V 300mA is well within it’s operating range. Sounds like a messed up circuit you say? That’s what I thought… but when I disconnect the external supply and instead connect the 5V and GND from the Arduino to the circuit the transistor passes the signal right along no problem… So the circuit is working correctly when power from the arduino is used, but not when my external source is used. My pump runs like a champ when hooked directly to it’s external (6V 300mA) power supply, yet the transistor switch circuit will not pass any juice through when triggered. I am trying to use my PN2222A transistor as a switch so a small liquid pump can run off an external (not from the Arduino) power source. Hello again everyone, I have returned with another head-scratcher. ![]()
