Tsinghua NeuroCam 4096-channel TFT ECoG array
NeuroCam is an active-matrix ECoG array: a metal-oxide thin-film-transistor (TFT) layer multiplexes thousands of sites onto a small number of wires. It comes from Sheng Xing’s group in the Department of Electronic Engineering, Tsinghua University, with Zhao Guoguang (Xuanwu Hospital, Capital Medical University) as co-corresponding author. Details are from Tsinghua’s Chinese news release (2 December 2025) and the Science Bulletin paper record (DOI 10.1016/j.scib.2025.11.030, PMID 41309324). The paper full text was not available to read, so material stack, site size and impedance are blank.
