1. A device for interfacing with a tissue in a biological environment, the device comprising:

  • a flexible or stretchable substrate;

    a flexible or stretchable electronic circuit comprising one or more inorganic semiconductor circuit elements supported by the flexible or stretchable substrate; and

    a barrier layer encapsulating at least a portion of the flexible or stretchable electronic circuit;

    wherein the barrier layer and the flexible or stretchable substrate limit a net leakage current from the flexible or stretchable electronic circuit to an amount which does not adversely affect the tissue; and

    wherein the flexible or stretchable substrate, the flexible or stretchable electronic circuit and the barrier layer provide a net bending stiffness of the device low enough that the device establishes conformal contact with the tissue in the biological environment.
