1. A system for amplifying deflection of a sensor, comprising:
a stretchable membrane having opposite fixed ends and a deflectable center portion; and
a layer disposed on the deflectable center portion of the stretchable membrane, wherein the layer has probe molecules thereon
such that bonding of target molecules to the probe molecules causes the surface stress of the layer to change thereby bending
the layer and deflecting the membrane, and wherein the layer covers only a central portion of the membrane such that deflection
of the layer is amplified by the deflection of the membrane, and wherein the stretchable membrane comprises a polymer chosen
from the group consisting of polyimide and parylene.
