Stretchable polymeric multielectrode array for conformal neural interfacing. [PDF]

Adv Mater, 2014
A highly stretchable neural interface of concurrent robust electrical and mechanical properties is developed with a conducting polymer film as the sole conductor for both the electrodes and the leads. This neural interface offers the benefits of conducting polymer electrodes in a demanding stretchable format, including low electrode impedance and high ...
