Microcantilever sensor platform for UGV-based detection
2010
The increased use of Unmanned Ground Vehicles (UGVs) drives the need for new lightweight, low cost sensors.
Microelectromechanical System (MEMS) based microcantilever sensors are a promising technology to meet this need,
because they can be manufactured at low cost on a mass scale, and are easily integrated into a UGV platform for
detection of explosives and other threat agents. While the technology is extremely sensitive, selectivity is a major
challenge and the response modes are not well understood. This work summarizes advances in characterizing ultrasensitive
microcantilever responses, sampling considerations, and sensor design and cantilever coating methodologies
consistent with UGV point detector needs.
