Piezoelectric

Ultra-thin piezoelectric elements with 150 Ω – 1,500 Ω impedance now available

April 1, 2025 By Aimee Kalnoskas

Same Sky’s Audio Group today announced the continued expansion of its piezoelectric elements product line. The CEB and CPT piezo element models feature extremely low profiles down to 0.12 mm and come with or without wire leads for simple and reliable design implementation in vibration detection or touch feedback applications. Externally driven and offering diameters […]

How is sensing used in audio acquisition and broadcasting? Part 4

July 31, 2023 By Randy Frank

Whenever a bridge collapses, sensor engineers propose the use of the latest and various technologies to prevent future catastrophes and the loss of human life. For example, microelectromechanical systems (MEMS) technology was proposed for bridge monitoring after the 2007 collapse of the I-35W bridge over the Mississippi River in Minneapolis. With more than 617,000 bridges […]

Piezo driver provides integrated sensing on single chip

September 28, 2022 By Aimee Kalnoskas

Boréas Technologies has introduced the BOS1921, a tiny piezo driver that delivers autonomous operation and sensing for piezo haptic trackpads in a single chip—freeing PC OEMs from the dedicated electronics that other piezo drivers require for force sensing. This advancement reduces bill of materials (BOM) costs by up to 2x, keeps piezo haptic trackpads thin, improves responsiveness, […]

How has sensing changed in industrial automation? (Part 1)

January 19, 2022 By Randy Frank

The Industrial Revolution or what we might call Industry 1.0 started over 250 years ago. In 1771 Richard Arkwright, today known as Father of the Factory System, used water to power the first fully automated spinning mill. One hundred years later, the automotive assembly line initiated the Second Industrial Revolution or Industry 2.0 with significantly […]

Creating unique devices with haptic touch technology

December 3, 2021 By Aimee Kalnoskas

By Nedko Ivanov, Aito Consumer technology products are becoming increasingly difficult for designers and manufacturers to differentiate. Laptops, in particular, are all of a similar size and shape and offer the same functionality. Clamshell laptops typically combine the same three features – a display, a keyboard, and a touchpad – with few aspects that distinguish […]

Thin film haptic actuators create high-fidelity in a localized way

March 23, 2021 By Aimee Kalnoskas

haptics

While piezoelectric haptic solutions are found in many applications, they are often large and heavy, thus shaking the entire device. KEMET’s new piezoelectric polymer film haptic actuators are thin (150 µm), flexible and conformable devices made from a proprietary, patent-protected paper-thin material, an electro-active polymer film, that enables piezoelectric effects to mimic the sense of […]

What is the difference between piezoelectric and piezoresistive pressure sensing?

January 11, 2021 By Randy Frank

Piezoelectric is the property of a material to generate a voltage when mechanical force is applied to it. In contrast, the piezoresistive effect is the property of a material’s resistivity to change when subjected to a mechanical force. In either case, the mechanical force or stress can be compression, tension or a bending force. Ceramic […]

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, […]

What is a Molecular Property Spectrometer sensor?

November 11, 2020 By Randy Frank

To measure and classify a wide range of combustible gases, NevadaNano has integrated multiple, complementary chemical sensors on a single silicon chip called the Molecular Property Spectrometer or MPS sensor. The chip’s patented array of micro-cantilevers with integrated piezoelectric sensing elements provides electrical actuation and sensing of resonance frequency. Monitoring resonance is a highly sensitive […]
