Micro-electro mechanical system

A printed wiring board having a switch, the switch comprising:

• a substrate comprising a substrate surface including a first region and a second region adjacent to the first region;
• a polymer coating applied to the first region, the polymer coating including a coating surface spaced apart from the substrate surface;
• a terminal disposed on the second region;
• a metallic trace affixed to the coating surface such that the metallic trace forms a extension over the second region, the extension having a rest position wherein the extension is spaced apart from the terminal and a flexed position wherein the extension is disposed towards the terminal;
• and
• an actuator disposed on the second region capable of creating an electric field effective to flex the extension from the rest position to the flexed position.

A printed wiring board having a variable capacitor, the variable capacitor comprising:

• a substrate comprising a substrate surface including a first region and a second region adjacent to the first region;
• a polymer coating applied to the first region, the polymer coating including a coating surface spaced apart from the substrate surface;
• a terminal disposed on the second region;
• a metallic trace affixed to the coating surface such that the metallic trace forms a extension over the second region, the extension having a rest position wherein the extension is spaced apart from the terminal and a flexed position wherein the extension is disposed towards the terminal;
• and
• an actuator disposed on the second region capable of creating an electric field effective to flex the extension from the rest position to the flexed position.
