NevadaNano (NevadaNanotech Systems, Inc.) develops and manufactures Micro Electro-Mechanical Systems (MEMS)-based sensor modules and subsystems for a diverse array of commercial and government applications. The products are used by system integrator partners and by system manufacturers because they benefit from the unique characteristics of our sensors — namely small size, low cost, unattended operation, and the ability to detect a broad range of threats with a single, standard sensor configuration.
The patented sensor technology was developed at the University of Nevada, Reno. Early R&D was supported by DARPA, the DOD, and the Department of Homeland Security. As a result, NevadaNano was founded in 2004. The company has now turned its focus to commercial applications, specifically, Internet of Things (IOT) enabled distributed gas sensing.
NevadaNano has spent a decade integrating multiple, complementary chemical sensors on a single silicon chip. We call it the Molecular Property Spectrometer™ (MPS). The MPS Gas Sensor works together to measure a variety of thermodynamic and electrostatic molecular properties of sampled vapors, liquids, and particles. In less than a second, the chip creates a large, rich dataset of chemical information. Then, Custom MPS software identifies the types of molecules present in an unknown sample.
The chip is an example of a microelectro mechanical systems (MEMS) because it exploits the many inherent advantages of MEMS. With its robust industrial design, the MPS doesn’t drift, decay, or poison and requires no maintenance over its lifetime. And with its data-rich reporting capabilities, the MPS will instantly let you know if a fault exists and why.
Additionally, in a span of milliseconds, the sensors can heat to hundreds of degrees Celsius, make a variety of high-precision thermal measurements, then cool back to room temperature. Various components of the system can detect picogram-scale masses and measure temperature with 0.01-degree resolution. It can operate in temperatures from -40°C to 75°C and all non-condensing humidity levels.
The chip incorporates a patented array of micro-cantilevers with integrated piezoelectric sensing elements that provide electrical actuation and sensing of resonance frequency. Monitoring resonance is a highly sensitive way to measure very small masses of adsorbed analyte. An array of sensors can be electrically monitored in a low-cost, robust fashion because of the unique piezoelectric configuration the MPS allows. Whereas, the more common alternative of using an optical readout is more expensive but less robust.
All MPS sensors have built-in resistive heaters so an assortment of thermal analyses (e.g. Differential Scanning Calorimetry) can be conducted. Also, this allows for the cleaning of each sensor after processing a sample. When necessary, these resistors also enable temperature and flow compensation in order to minimize sensor noise and drift and further enhance sensitivity.
