The question behind this study
A ray-inspired soft robot combines cardiomyocytes, patterned hydrogels and gold microelectrodes. The electrodes provide mechanical support and local electrical stimulation for cell-driven actuation.
What the study shows
PEG/CNT–GelMA layers and gold microelectrodes form a cardiomyocyte-driven ray-like robot.
Microelectrodes combine mechanical support with local electrical stimulation. This in vitro actuator used neonatal rat cardiomyocytes and did not generate forward propulsion.
AI-generated, not-to-scale concept based on the public abstracts, showing electrically driven actuation through a PEG/CNT–GelMA structure, cardiomyocytes and gold microelectrodes.

Open questions
How stable is the electrode–gel connection during repeated contractions and extended culture?
Conditions for comparison
Compare matched cell maturity, body geometry, stimulation location and frequency, and fluid conditions.

A cardiomyocyte-driven ray with a gold skeleton uses optogenetic steering, offering a light-controlled counterpart to local electrical stimulation.
This connection is based on the PubMed abstract. Stimulation methods, body structures and muscle patterns differ, so swimming speed alone cannot rank the designs.
