Shape memory polymer substrates are utilized to create 3D softening substrates for neural interfaces. This substrate system softens in vivo from more than 600 to 6 MPa. A nerve cuff electrode that coils around a 1 mm diameter vagus nerve in a rat and is still capable of driving neural activity is demonstrated.
