How are ultrasonic MEMS sensors being used for 3D obstacle detection and collision avoidance?

April 4, 2022 By Randy Frank

In addition to radar, LiDAR and camera sensing used in 3D obstacle detection and collision avoidance in advanced driver assistance systems (ADAS) in vehicles, ultrasonic sensing has been used as well. Traditionally, the ultrasonic sensors used transducer-based technology to provide a microphone to transmit and receive the ultrasonic signal in passenger vehicle parking applications. Using Infineon’s […]

How do time-of-flight sensors work?

March 8, 2022 By Randy Frank

Using the time-of-flight (ToF) principle, a ToF sensor measures the distance between the sensor and an object. The sensor emits a signal that is reflected off an object and then detects the time for a round trip to occur. Typically, either light or sound waves can provide the transmitted signal.  In either case, the distance […]

How to design an effective telehealth system

July 20, 2021 By WTWH Editor

Telehealth

By Marcel Consée, Mouser Electronics Healthcare can be deeply personal, and direct contact between patients and medical personnel remains vital. However, taking the relationship between doctors and nurses out of the equation can sometimes make sense. Medical crises such as the global COVID-19 pandemic accelerate the adoption of telehealth methods, even though the original idea […]

An introduction to ultrasonic sensors

June 22, 2021 By WTWH Editor

Ultrasonic sensors have been a popular method for distance measurement and object detection for many years. Their basic operating principle works by measuring the amount of time it takes for their emitted ultrasonic pulse of sound to bounce off an object and return, hence the name ultrasonic sensor. With the market for autonomous robots, vehicles, […]

Graphene-based flowmeter sensor measures nano-rate fluid flows, Part 1: The challenge

April 16, 2021 By Bill Schweber

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 […]

The working principle, applications and limitations of ultrasonic sensors

January 7, 2021 By Lynnette Reese

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 […]

What is exponential technology?

November 13, 2020 By Randy Frank

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, […]
