The present invention is directed to improved microdevices and methods of manufacturing such devices. More particularly the present invention is directed to the use of a compound having the general structure (formula (I)): wherein R is selected from the group consisting of C-Calkyl, C-Calkenyl, C-Calkynyl, C-Ccycloalkyl, and C-Caryl for bonding silica based substrates to plastic substrates or to other silica based substrates. In addition the polymer can be used to coat microchannels to enhance the physical properties of the microdevice 

Hybrid polymers for functional tuning of microfluidic device surfaces

A simplified MEMS optical display device driven by electrostatic forces and associated arrays are provided for. The optical display device includes an optically transparent substrate, an optically transparent fixed electrode disposed on the substrate and a pigmented translucent film disposed on the substrate. A moveable optical shutter is affixed to the substrate and is generally aligned with the fixed electrode and the pigmented translucent film. The moveable optical shutter comprises an electrode element and a biasing element. In addition, a fixed portion attached to the substrate and a distal portion adjacent to the fixed portion defines the optical shutter. When an electrostatic voltage differential is established between the fixed electrode and the optical shutter electrode element the distal portion of the optical shutter will move to controllably regulate the pigmentation of an optical signal.
