With last year’s sensing/sensor events cancelled or held virtually after COVID -19 hit, it is interesting to monitor how they are being held this year. Some recent announcements provide an indication. The 35th International Conference on Micro Electro Mechanical Systems (IEEE MEMS 2022) will be held in-person in Tokyo, Japan, as well as virtually on […]

How can Wi-Fi sense without sensors?
With over 105 patents filed and pending and 45+ patents granted worldwide, Origin Wireless Inc.’s Hex Home security system uses patented Wireless AI™ technology to provide WiFi Sensing™. The Hex system consists of a home master command, remote devices and an app. Devices are located about 15 to 30 feet from each other. Installation requires […]
What is the difference between sensors for low UV, middle UV, and UV-C light?
Unlike visible light, which ranges between 380 nm and 780 nm, ultraviolet (UV) light wavelengths measure between 100 nm to 400 nm. UV is broken into subcategories known as UVA, UVB, or UVC. While UVC rays are the shortest and strongest, naturally occurring UVC rays are mostly absorbed by the atmospheric ozone layer, so they […]
What is the difference between an NTC and a PTC thermistor?
Both negative temperature coefficient (NTC) and positive temperature coefficient (PTC) thermistors’ values change as a result of temperature but impact their use differently. For NTC thermistors, as temperature increases, the resistance drops from high to low and allows current to pass through. In a circuit, they can limit in-rush current by self-heating when current is […]
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 […]
The role of ADAS sensors in automotive design
Advanced Driver Assistance Systems (ADAS) are intended to prevent deaths and injuries by reducing accidents. Exemplary ADAS applications include: pedestrian detection/avoidance, lane departure warning/correction; traffic sign recognition; automatic emergency braking, and; blind-spot detection. This FAQ starts with an overview of the “levels of driving automation” and its relation to ADAS. It then reviews the role […]
Sensors, sensors everywhere. Now what do I do?
By Moshe Sheier, Vice President of Marketing at CEVA Mobile computing has driven an explosion in product opportunities – smartphones, wearables, hearables, sports cameras, and more. Sensing will further extend opportunities in applications which must be environment-aware. Now it’s commonplace to think about object recognition and collision warning through visual, radar, or Lidar sensing. Short-range […]
How can thousands of wireless sensors be deployed without requiring battery maintenance?
Wireless applications that need continuous monitoring to save energy, detect unsafe or other avoidable conditions and need to avoid creating serious maintenance issues are prime candidates for energy harvesting. Steam trap monitoring provides an excellent example of this type of batteryless sensing. Roughly 20% of the steam leaving a typical facility’s central boiler plant in space […]
Can the AgeMeter help you?
Developed by Centers for Age Control, the AgeMeter takes user data and physiological biomarker tests to calculate functional age and provide other age-related feedback to users. Since it tests physiological biomarkers that decline with age, the AgeMeter can validate aging reversal as well as anti-aging therapies for healthcare practices, researchers, fitness programs and consumers. Intended […]
An introduction to ultrasonic sensors
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, […]
