Mechanically adaptive supercontractile polymer for soft bioelectronics

Achieving standardized bioelectronic interfaces adapted to different arbitrary shapes and sizes of biological tissues is a significant challenge. Breaking away from traditional suturing or adhesion techniques, a mechanically adaptive supercontractile polymer film is developed to yield large and rapid contractions around soft, wet, and irregular tissues. As demonstrated, polymer-based electrodes could provide reliable in vivo nerve stimulation and electrophysiological signal recording.
