Northwestern Engineers Print Neurons to Talk to Brain

Engineers at Northwestern University developed flexible, printed artificial neurons that communicate with biological brain cells ^[1]. These low-cost devices mimic natural voltage spikes in duration and timing ^[2]. In tests, the artificial neurons successfully triggered responses within living mouse brain tissue ^[3]. This work points toward energy-efficient AI hardware and advanced neuroprosthetics ^[1]. These flexible devices are designed to be low-cost while maintaining high precision ^[2]. Researchers aim to further integrate electronic components with biological systems to improve future medical technology ^[3].
