How sensitive is a vibrometer? Can it pick up the response change because of minute changes in a sample’s thickness or mass? The change would result in a very small shift in natural frequency.

This fascinating study demonstrates this exceptionally well using Polytec’s PSV-500 https://www.polytec.com/us/vibrometry/products/full-field-vibrometers/psv-500-scanning-vibrometer. Vibrometry took a quantum leap when Polytec unleashed QTec® technology. Have you tried QTec® yet?

Read this fascinating study from researchers at Tsinghua University and Beihang University, where they utilized a Polytec MSA-100-3D scanning vibrometer https://www.polytec.com/us/vibrometry/products/microscope-based-vibrometers/msa-100-3d-micro-system-analyzer to analyze a bio-inspired graphene nano-fiber (GNF) drum. Displacements and mode shapes were measured with excitation frequencies in the human auditory range. This study holds significant potential for advancing the design of artificial tympanic membranes and ultra-sensitive microphones.

Figure A. The principle of the biomimetic GNF imitates fabric-type natural hearing organs, such as a tympanic membrane and spider web.

Figure B. Comparison of modulus and thickness of (i) graphene fibers, (ii) graphene films, (iii) graphene aerogels, and (iv) graphene fabrics. The red dashed line, as a constant value of a function of modulus and thickness, represents the deflection capacity.

A unique twist on the design of a haptic actuator. The key motivation for the study is to develop a miniaturized, robust haptic actuator with properties suitable for skin stimulation. The design separates mechanical and electrical functions for ease of fabrication while achieving high performance in terms of low-frequency/high-amplitude characteristics.

Polytec is at the forefront of haptic research, with applications spanning XR, education, and training. This study features our trusted MSA-500 Micro System Analyzer. Be sure to explore its advanced successor, the MSA-600 Micro System Analyzer https://www.polytec.com/us/vibrometry/products/microscope-based-vibrometers/msa-600-micro-system-analyzer, designed to meet the requirements of the future!

Imagine a world where your smartwatch or Bluetooth earbuds never need charging! Thanks to the power of triboelectric nanogenerators (TENG), that future is within reach. TENGs generate electricity through the "triboelectric effect," where electric charge is created when two different materials come into contact and then separate. These tiny generators have incredible potential for energy harvesting, self-powered sensors, and powering small electronic devices.

In a recent study, researchers achieved a significant breakthrough in TENG-based vibration sensors, boasting a flat frequency response up to nearly 10 kHz! The authors show an example measurement for speech recognition sensor, using Polytec’s CLV-2534 to validate the performance. Find out more about VibroOne https://www.polytec.com/us/vibrometry/products/single-point-vibrometers/vibroone, the successor to CLV-2534.

Polytec’s VibroGo portable vibrometer was recently featured on the Netflix series "The Secret World of Sound" narrated by the legendary Sir David Attenborough! Episode 2 of the series dives into the mesmerizing world of nature's hidden symphonies and discovers how technology is bridging the gap between us and the tiniest of creatures.

In a groundbreaking study, Dr. Rex Cocroft from the University of Missouri used VibroGo to uncover the secret communication methods of treehoppers. These tiny creatures communicate through vibrations, and thanks to the portable vibrometer, we can now listen to their fascinating "silent songs." Catch the latest episode!

allows for the precise manipulation of fluids on a sub-millimeter scale, facilitating the creation of compact, efficient, and cost-effective devices for various biological and chemical applications, thanks to the benefits of miniaturization.

This fascinating study tackles a major challenge in the field: how to produce microfluidic devices in a cost-effective and efficient manner. The research, conducted by Professor Tony Jun Huang's group at Duke University, overcomes this hurdle by utilizing 3D printing to create a surface acoustic wave (SAW)-based microfluidic device. These devices were characterized at several megahertz frequencies using the Polytec VibroFlex-Compact https://www.polytec.com/us/vibrometry/products/single-point-vibrometers/vibroflex

Imagine sliding your fingers on a touch display and "feeling" the texture of skin, the roughness of a piece of cloth, or characters in Braille for the visually impaired. Dr. Rebecca Friesen's paper (published while she was Prof. Ed Colgate's student) is an excellent primer for anyone interested in this fascinating field of research. Haptics, described by someone as the "language of the skin," is such a fundamental and intuitive mode of communication that it's astonishing we haven't utilized it more extensively.

is grateful for the opportunity to help characterize the finger on a textured surface using one of our laser Doppler , IVS-500 https://www.polytec.com/us/vibrometry/products/single-point-vibrometers/ivs-500-industrial-vibration-sensor in this case. Our goal was to measure the amplitude, frequency, and damping of the transmitted vibrations. These measurements help define the digital parameters needed to simulate the desired texture.
