An electrokinetic device is configured as a dynamic lens cover and/or filter for an imaging assembly, e.g., of a mobile device, to selectively allow electromagnetic radiation to pass through a lens of the imaging assembly when the dynamic lens cover is in a first operating state or to prevent electromagnetic radiation from reaching the lens of the imaging assembly when the dynamic lens cover is in a second operating state. The electrokinetic device includes transparent first and second substrates, and a compaction trench surrounding the lens of the imaging assembly. The compaction trench stores pigment when the dynamic lens cover is in the first operating state. In the second operating state pigment is dispersed within a carrier fluid between the first and second substrates.

Applications of an electrokinetic device for an imaging system

A surface enhanced luminescence (SELS) sensor may include a substrate and nano fingers projecting from the substrate. Each of the nano fingers may include a polymer pillar having a sidewall and a top, a coating layer covering the sidewall and a metal cap supported by and in contact with the top of the pillar.

SELS nano finger sidewall coating layer

A method for forming a surface enhanced Raman spectroscopy (SERS) sensing apparatus may include providing a body having an internal microfluidic passage, the microfluidic passage having an interior surrounded by an interior surface, depositing a conformal inorganic passivation film onto the interior surface so as to continuously surround the interior by atomic layer deposition and positioning a SERS sensor in connection with the microfluidic passage after the depositing of the conformal inorganic film.
