When it comes to nearly all biological measurements, the ranges of many of the parameters of interest are orders-of-magnitude below those with which many engineers are familiar. Instead of megahertz or even kilohertz, the living-creature world is in the single or double-digit hertz range, such as the roughly 60+ beats per minute (BPM) for a […]
Ultrasonic
The working principle, applications and limitations of ultrasonic sensors
The ultrasonic sensor (or transducer) works on the same principles as a radar system. An ultrasonic sensor can convert electrical energy into acoustic waves and vice versa. The acoustic wave signal is an ultrasonic wave traveling at a frequency above 18kHz. The famous HC SR04 ultrasonic sensor generates ultrasonic waves at 40kHz frequency. Typically, a […]
The next level of ultrasonic technology from Pepperl+Fuchs
Ultrasonic sensors have rapidly gained popularity in recent years—what was once a niche product has now become a key technology that can be found almost everywhere in the automation sector. As the market leader in this sector, Pepperl+Fuchs will be dedicating a whole day of events at its second Online Summit to providing insight into the […]
What is exponential technology?
In his presentation at the COMSWORLD2020 virtual event, Janusz Bryzek of eXo Imaging, described many details to support his premise of the exponential acceleration of healthcare problems. According to Bryzek, the convergence of exponential technologies or ExTech is accelerating the availability of healthcare to all. Exponential technologies include different types of health sensors, big data, […]

How does a finger unlock a door?
At Sensor Expo 2019, Marcia Ratton from TDK InvenSense demonstrates how the UltraPrint Sensor (TCFS-3000) precisely identifies a finger print. Integrated into a door lock, the image from the sensor is displayed on a screen to demonstrate the clarity and details of the image. The ultrasonic fingerprint imaging uses proprietary InvenSense, a TDK Group company, […]
What’s new in sensors for autonomous vehicles? Part 1
Tesla, one of the leaders in autonomous, self-driving vehicles boasts 8 vision cameras, 12 ultrasonic sensors and radar on all of the vehicles it is currently building according to recent company tweet. To make the right decisions by using the data from these sensors in the timeliest manner through sensor fusion, Tesla has developed a […]
What types of sensors are used in robots? Part 1 of 2
Fully functional human robots, such as those being developed by Boston Dynamics, need numerous sensors to simulate a variety of human and beyond human capabilities. For the human part, the sensors provide the ability to see, hear, touch and move. In general, industrial robots employ sensors for a variety of activities. Some sensors provide environmental […]
New Phantom powered preamplifier
A new universal preamplifier from PCB Piezotronics reduces project costs by allowing users to interchange multiple test microphone cartridges to meet unique testing requirements. Model 426A14 adapts to any IEC 61094-4 compliant, prepolarized microphone for use in loudspeaker design, microphone and amplifier modeling, and live sound or high definition recording applications. The preamplifier may be purchased […]
