Phototactic guidance of a tissue-engineered soft-robotic ray.

Science (New York, N.Y.) Jul 8, 2016
Inspired by the relatively simple morphological blueprint provided by batoid fish such as stingrays and skates, we created a biohybrid system that enables an artificial animal--a tissue-engineered ray--to swim and phototactically follow a light cue. ...
