UChicago scientists invent ultra-thin, minimally-invasive pacemaker controlled by light


Ultralight membrane can regulate heartbeats with the aid of an optic fiber

“The early experiments have been very successful, and we’re really hopeful about the future for this translational technology,” said Pengju Li, a graduate student at the University of Chicago Pritzker School of Molecular Engineering and first author on the paper. A screening method developed by Li to map the photoelectrochemical output of various silicon-based materials could also have uses elsewhere, Tian pointed out, such as in fields like new battery technologies, catalysts, or photovoltaic cells. The other UChicago authors on the paper were Jing Zhang, Hidenori Hayashi, Jiping Yue, Wen Li, Chuanwang Yang, Changxu Sun, Jiuyun Shi, and Judah Huberman-Shlaes.
