Microcantilever-Based Sensor Array to Detect Various Chemical Vapor Analytes


Laboratory: Lawrence Livermore National Laboratory (LLNL)

Technology: The term “electronic nose” describes several sensor technologies that have been developed to detect chemical and biological agents of interest in the vapor phase. Many researchers have applied these devices to various fields of human interest, including medical diagnosis and quality control monitoring in the food and beverage industry. The escalation of homeland security concerns has spurred the development of electronic noses that have the potential to effectively detect chemical and biological agents, and toxic industrial compounds at sub-lethal concentrations. LLNL has developed a compact and low-power cantilever-based sensor array, which has been used to detect various vapor-phase analytes.


This invention can provide a solution for chemical detection in a miniaturized, low-power device that requires no consumables. LLNL’s device has been designed to be robust and operational in harsh chemical or environmental conditions.
