Healthcare and fitness are increasingly important to many people. The ease of making measurements or showing improvement metrics and the amount of data that can be provided by a minimal, non-invasive process makes the ongoing effort sustainable. Bioelectrical impedance (or bioimpedance) analysis (BIA) provides users with a technique that is easily integrated into smart watches […]
Frequently Asked Question (FAQ)
What is 3D scanning?
Since 3D scanners have become more affordable, 3D scanning has changed the world of custom 3D printing. Once, 3D scanning was only used in military equipment and spacecraft parts production. With desktop and handheld 3D printers available for a few hundred dollars, 3D scanning has found a place in home fun and hobby projects. You […]
Hybrid sensors for connected vehicles
The dependence of smart vehicle features on sensing technology has manufacturers thinking about how to field devices that combine functions in economical ways. Estimates are that today’s vehicles can have between 60 and 100 sensors onboard. And over the next decade the number of sensors is expected to double. No wonder, then, there are efforts […]
How are wearable systems improving?
At the Wear 2022 Conference in Scottsdale, AZ, presenters from several companies described wearable products that used textile-based sensors. The end products included socks, boots, pants, shirts, leggings, wristbands, headbands and more. Textile-based sensing capabilities range from temperature and pressure to biosensors and more. Primary wearable end markets include healthcare and fitness/training. “We design 100% […]
How can you easily evaluate a MEMS microphone ?
Microelectromechanical systems (MEMS) technology is used for many sensing applications including microphones. The MEMS microphone provides a design alternative to Electret Condenser Microphones (ECMs) for many consumer electronic and mobile products. With this goal in mind, Infineon Technologies silicon microphones have been designed to extend the benefits of lowest possible self-noise (high SNR) and lowest […]
How can wearable sensors help diabetics?
According to the Centers for Disease Control and Prevention, over 30 million people in the United States (> 9%) have been diagnosed with diabetes. Globally, over 422 million people suffer from diabetes, according to the World Health Organization. In many countries, including the USA, diabetes is considered an emergency of epidemic proportions with diabetic foot […]
Want to develop a wearable product?
If so, the Sensoria Developer Kit (SDK) could be the answer. Recognizing that there are so may scenarios for improving healthcare through wearables and remote monitoring, that they cannot serve them all by themselves, Sensoria Health offers the SDK as a way to partner with those interested in a new approach. Having the vision that […]
What are the sensor challenges in wearables?
In his introductory keynote address at Wear Conference 2022, Pankaj Kedia, Sr. Director & GM of the Smart Wearables Segment of Qualcomm Technologies, Inc., noted that hyper segmentation is occurring in the wearables market segment. While the needs of healthy people seeking to improve their health versus patients who need to carefully monitor their health […]
How does the PICMG IoT.1 specification for smart IoT sensors work?
The PCI Industrial Computer Manufacturer’s Group (PICMG) is developing a series of specifications to enable plug-and-play interoperability of smart sensors and effectors. The effort includes the large installed base of legacy non-IoT (not IP-enabled) devices and newer IoT-enabled smart sensors. The PICMG program includes development of a family of three IoT specifications. PICMG IoT.1 is […]
What’s the difference between 2-, 3-, & 4-wire RDT sensing?
The difference is measurement accuracy. Using 2-wire resistance temperature detector (RTD) sensing provides good accuracy (maybe), the accuracy of 3-wire sensing is better, and 4-wire sensing provides the best accuracy. In addition, there’s the option of using Wheatstone bridge topologies to improve the performance of 2- and 3-wire RDTs. This FAQ begins with a review […]
