Choosing the Right Potentiometer for Reliable Sensing

In today’s market, there are a variety of available types of position sensing systems. It is important to compare unique features to application needs in order to find the best fit. A potentiometer sensor is an electromechanical component that consists of a resistor where the voltage divider value can be measured at any position by means of sliding contacts between the applied voltage values. Physically, a potentiometer consists, at a minimum, of a resistance track, a collector track, and a sliding contact that can be moved along the resistance track by means of mechanics (Figure 1). The movement of the sliding contact can be rotatory (angle) or translational (path).

2015 Create the Future Design Contest: Aerospace & Defense Category Winner

N5 Filo (First-In-Last-Out): An Ultra-Small, Low-Cost Hazardous Gas Detector Using Novel Chip-Scale Chemical Sensor Technology Abhishek Motayed, Ratan Debnath, Baomei Wen, Audie Castillo, Ting Xie, and Gavin Liu, N5 Sensors Inc., Rockville, MD N5 Sensors is a University of Maryland spinoff that is commercializing a disruptive chipscale gas sensor technology for industrial, environmental, and safety monitoring. The microsensor arrays on a single chip could replace multiple conventional macro-scale gas sensors used in portable multi-gas detectors. These new sensors are small, accurate, low power, and capable of detecting multiple gases at the same time. Using a patent-pending sensing architecture, N5 is working to develop low-cost, ultra-compact, multi-gas detectors that can be interfaced with mobile devices, allowing industrial workers, first-responders, and soldiers to assess the dangers of their surroundings rapidly and accurately in real time using their smartphones or other mobile devices.

2015 Create the Future Design Contest: Electronics Category Winner

Real-Time Fiber Optic Sensing System Lance Richards NASA Armstrong Flight Research Center Edwards, CA A team at NASA Armstrong has developed fiber optic sensing system (FOSS) technology that represents a major breakthrough in high-speed operational monitoring and sensing. Driven by ultra-efficient algorithms, FOSS can be used to determine, in real time, a variety of critical parameters including strain, shape deformation, temperature, liquid level, and operational loads. This state-of-the-art sensor system delivers reliable measurements in the most demanding environments confronted by aerospace, automotive, and energy sectors. FOSS is ideal for monitoring the structural health of aircraft, buildings, and dams; improving the efficiency of turbines and industrial equipment; and detecting instabilities within tunnels and power plants.
