The main aim of this study is to introduce a new kind of bio- and chemical sensors based on membrane structure. In this project we focus on investigating about the mechanical properties of the silicon membrane in nano scale and also exploring about the effect of liquid environment on mechanical behaviour of this structure.

Micro and nano electromechanical devices can be used for the detection of small forces and masses. A cantilever beam is one of the simplest mechanical structures which now is widely used in nano and micro scales as sensing probe. However, given the liquid environment and the small signals involved in the biological characterization, the probes used must have special performances. We are therefore working in the development of specific probes which have electrically insulated space so that they can be operated with low noise, in liquid as well: Silicon plate. An ultra-thin conductive membrane with a nano meter-scale thickness may allow extraordinary sensitivity and dynamic range, which makes it a candidate for the next generation of membrane-based sensors such as bio-/chemical, pressure, tactile, and acoustic sensors.
