HBM , Inc. (www.hbm.com), introduces its FIT7A digital load cell. The FIT7A load cell not only provides nearly the same speed and accuracy of Electromagnetic Force Restoration (EFR) sensors normally found in modern packaging machines, but it does so at 60 percent less cost. This new strain gauge-based load cell makes it possible to develop […]
Smart Fabric Sensors Make Physical Measurements
Existing wearable sensors measure physiology (EKG, EMG), electrical conductivity or breathing. In contrast, patented, proprietary monolithic fabric sensor technology from Bebop Sensors Inc. allows physical measurements including bend, location, motion, rotation, angle, size, pressure, force and torque. The sensors’ continuous real-time reporting and 3D mapping capability can enable applications such as: answering calls from a shirt […]
Reducing Cost at the Wafer Level for MEMS Sensors
At the MEMS Industry Group’s MEMS Executive Congress 2012 held Nov 7-9 in Scottsdale, AZ, I had the chance to talk to several attendees about issues impacting MEMS (microelectromechanical systems) sensors. Perhaps one of the most important areas for increased sensor proliferation, especially for consumer applications, is reduced cost. Eric Pabo, business development manager for […]
Simplifying Precision Current Measurements
Amplifying the voltage drop across a manganin shunt is a common technique for current sensing. Micro Oscillator, Inc.’s family of sMart shunts provides a simplified alternative. The high-side precision current sense amplifier circuit has a built-in sense resistor. The patent pending product family provides a high-precision voltage or 20 mA current loop output while maintaining […]
