Research team from Peking University published their findings in the journal "Nature," indicating the potential for improved sensitivity of intelligent sensor chips.

In the future, the sensitivity of smart wristbands is expected to be more accurate, and the screens of foldable phones will also become "brighter". This is thanks to the latest research results released by the team led by Professor Pei Jian from the School of Chemistry and Molecular Engineering at Peking University: for the first time in the world, ultra-high precision doping of organic high-polymer semiconductors at the submicron level has been achieved, and the sensitivity of smart sensing chips is expected to improve. "The precision processing of organic semiconductors is like finding water in the desert," Pei Jian vividly explained the difficulty and importance of research in this field. Compared to traditional inorganic semiconductors, organic semiconductors have advantages such as being lightweight, thin, flexible, low cost, and environmentally friendly, and they have shown great potential in areas such as organic photovoltaic cells and flexible sensors.
