An electronic detachment technology based on thin films of a poly(3,4‐ethylenedioxythiophene) derivative is evaluated for controlled release of human epithelial cells. When applying a potential of 1 V, the redox‐responsive polymer films detach and disintegrate and at the same time release cells cultured on top in the absence of any enzymatic treatment with excellent preservation of membrane proteins and cell viability.
