Stretchable Microelectrode Arrays for Electro‐Mechanical Probing of Brain Spheroids

Advanced Healthcare Materials, EarlyView.
A multimodal device featuring kirigami‐patterned stretchable microelectrode arrays enables concurrent mechanical actuation and electrophysiological recording of brain spheroids. The platform supports multiple loading regimes and reveals mechanically induced modulation of spontaneous network activity in 3D neural tissue models.
