A photo sensor according to an embodiment includes a semiconductor substrate. The preferred polymeric compositions are produced through the polymerization of one or more siloxysilane monomers or the copolymerization of one or more siloxysilane monomers with one or more aromatic or non-aromatic non-siloxy monomers, hydrophobic monomers or hydrophilic monomers. The voltage is applied in response to a feedback signal produced by at least one feedback sensor, which may be a displacement sensor or some other type of sensor.
