Teams at the Perelman School of Medicine (Penn) and Harvard reported in Science that an ultrathin, flexible electronic mesh implanted within developing pancreatic tissue records and delivers circadian‑like electrical stimulation that drives functional maturation of stem‑cell‑derived islet cells. The device improved insulin secretion dynamics in vitro and in animal models. A related bioengineering report introduced 'cyborg' pancreatic organoids integrating soft electronics for continuous monitoring and control of islet development. Together, the studies propose an engineering‑first route to produce mature, functional islets for diabetes research and potential cell‑replacement therapies, while raising translational questions on biocompatibility, scale‑up and regulatory pathways for electronics‑embedded tissues.
