Using ultrasonic sensors in noisy environments can cause the sensor to detect false ultrasonic signals created by whistles, brakes, animals, machinery and other sources.  One method to minimize this problem is to use a multifrequency ultrasonic transmission chirp.  SensComp’s 600 series electrostatic transducers can be used for this application.  Unlike piezo transducers that operate at […]

The Challenge: Why Standard Piezoelectric Sensors Fail Modern AGVs Automated Guided Vehicles (AGVs) and Autonomous Mobile Robots (AMRs) are the backbone of modern material handling. Yet the efficiency of an AGV is limited by its ability to perceive its environment. If an AGV can’t reliably detect a forklift tine at 15 feet or a warehouse

Electrostatic ultrasonic sensors and transducers deliver performance advantages that piezoelectric sensors cannot match—particularly in applications that require long range, soft-target detection, small-object recognition, or stable operation across temperature changes. By leveraging a lightweight electrostatic membrane rather than a heavy ceramic disk, these sensors achieve up to 40 dB higher sensitivity, and maintain consistent performance in conditions

When most engineers think about in-air ultrasonic sensing, they picture a cheap, ceramic “hockey puck” — a piezoelectric transducer. But piezo is not the only option, and not always the right choice. Electrostatic ultrasonic sensors use a different transduction mechanism that delivers higher sensitivity, wider bandwidth, and more stable performance in demanding in-air applications. How
