A research team headed by Professor Huang Jia from the School of Materials Science and Engineering at Tongji University has achieved remarkable success in the development of two innovative organic transistor sensing devices. The team has unveiled a highly stretchable and high-transconductance organic electrochemical transistor (OECT) and, in collaboration with the Shanghai Institute of Technical Physics at the Chinese Academy of Sciences, a bionic mid-infrared neuromorphic transistor. Both studies, which delved into the chemical, tactile-like, and visual-like sensing capabilities of these devices, yielded outstanding results and have been consecutively published in Nature Communications.

The OECT research overcame a long-standing technical hurdle faced by traditional devices, wherein enhancing ion permeation/transport efficiency and mechanical properties simultaneously proved challenging. The developed OECT demonstrates high transconductance, a superior on/off ratio, and exceptional stretchability. Meanwhile, the bionic mid-infrared neuromorphic transistor excels in efficiently perceiving and remembering mid-infrared light, showcasing immense potential for applications in complex environments.
