Use of a reactive, or reducing gas as a method to increase contact lifetime in micro contact MEMS switch devices
A MEMS device comprises an electro mechanical element in a sealed chamber containing a gas comprising a reactive gas selected to react with any contaminants that may be present or formed on the operating surfaces of the device in a manner to maximize the electrical conductivity of the surfaces during operation of the device. The MEMS device may comprise a MEMS switch having electrical contacts as the operating surfaces. The reactive gas may comprise hydrogen or an azane, optionally mixed with an inert gas, or any combination of the gases. The corresponding process provides a means to substantially reduce or eliminate contaminants present or formed on the operating surfaces of MEMS devices in a manner to maximize the electrical conductivity of the surfaces during operation of the devices.
Electrostatic actuator
An actuator is configured to include a first substrate that has a first conductive surface, which may be or include a first conductive electrode layer. The actuator also includes a second substrate that has a second conductive surface, which may be or include a second conductive electrode layer. The first and second conductive surfaces face toward each other across a compression space between the first and second substrates. A group of elastic support nodules span the compression space and separate the first and second conductive surfaces. The compression space is less than fully filled with solid elastic material and is configured to be compressed by relative movement of the first and second conductive surfaces toward each other in response to a voltage difference between the first and second conductive surfaces.

Electrostatic Protection Device and Manufacturing Method Thereof and Array Substrate
An electrostatic protection device (10) includes: a first conductive layer (110), a second conductive layer (140) and a polarization film layer (130), in which the polarization film layer (130) is disposed between the first conductive layer (110) and the second conductive layer (140) and formed of a piezoelectric material which is capable of deforming when applied with electricity; a conductive cantilever (150), disposed on the second conductive layer (140) and including a free end (152); and a charge diffusion layer (170), disposed at a side of the conductive cantilever (150) away from the polarization film layer (130), electrically connected with the first conductive layer (110) and spaced apart from the conductive cantilever (150), in which upon a voltage difference between the first conductive layer (110) and the second conductive layer (140) reaching a predetermined value, the polarization film layer (130) deforms to allow the conductive cantilever (150) to connect with the charge diffusion layer (170). The device provides the conductive cantilever (150) which is in a suspended state in a case where the voltage difference between the first conductive layer (110) and the second conductive layer (140) does not reach the predetermined value, so the first conductive layer (110) and the second conductive layer (140) are disconnected so that the load of the first conductive layer (110) and the second conductive layer (140) are prevented from being influenced.
