Blind or visually impaired individuals have to rely on other senses and typically have heightened capability – especially for hearing and touch. Using a white cane provides feedback in both of these areas. World Health Organization (WHO) data says that there are more than 253 million visually impaired people worldwide. Many of these individuals rely […]

Ultrasonic ToF sensors work at short and long ranges
TDK Corporation has introduced the Chirp ICU-10201 and ICU-20201, two new high-performance, ultra-low power integrated ultrasonic Time-of-Flight (ToF) sensors for short- and long-range detection. The new MEMS sensors embed a more powerful on-chip processor with higher computational power; the enhanced processing capabilities allow a wide range of application algorithms to fit and to run on-chip, […]
Ultrasonic sensor guides AGVs, robots, and other industrial apps
Toposens GmbH is officially releasing its new Ultrasonic Echolocation Sensor for 3D Collision Avoidance. The industrial-grade sensor development kit, called ECHO ONE DK, is the next level development based on the company’s proven 3D ultrasonic technology, which mimics a bat’s echolocation techniques. Unlike existing sensor technologies that can be negatively impacted by lighting conditions or […]
Pepperl+Fuchs introduces Ultrasonic Sensors for safety applications
Pepperl+Fuchs is expanding its factory automation portfolio with the all-new USi-safety ultrasonic sensor. Suitable for use in harsh environments and even for outdoor applications, this small but mighty sensor requires only a small amount of installation space. With safety certification in accordance with EN ISO 13849 category 3 PL d and as the only sensor […]
How to design an effective telehealth system
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 […]
Graphene-based flowmeter sensor measures nano-rate fluid flows, Part 3: The sensor
The first part of this article looked at the challenges of sensing nano-level flow rates such as found in the blood vessels. In contrast, the second part looked at graphene, an allotrope of elemental carbon at the heart of a new sensor used to measure those flows. This third and final part looks at the […]
Graphene-based flowmeter sensor measures nano-rate fluid flows, Part 2: The graphene context
The previous part of this article looked at the challenges of nanoflow sensors, especially with respect to blood flow. This part looks at graphene, which is the basis for the new sensor. Graphene is a material structure which did not exist until relatively recently. However, its constituent element of graphite – the crystalline form of […]
Graphene-based flowmeter sensor measures nano-rate fluid flows, Part 1: The challenge
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
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 […]
