A V-Shaped Microcantilever Sensor Based on a Gap Method for Real-Time Detection of Bacteria.

This paper presents a dynamic-mode microcantilever sensor based on a gap method. The sensor has a V-shaped microcantilever and a fixed structure at a distance of 2 µm from its free end. The microcantilever is excited by applying an ac electric potential (3 V) to its piezoelectric pads and vibrates at its fundamental resonant frequency.
