Adjustable Acoustic Metamaterials

Adjustable Acoustic Metamaterials are engineered materials designed to dynamically control, manipulate, and adapt sound and vibration in ways not achievable with conventional materials. Unlike static acoustic metamaterials, adjustable (or tunable) acoustic metamaterials can change their acoustic properties in real time in response to external stimuli, enabling flexible and multifunctional sound control.

These metamaterials are structured at subwavelength scales and allow active tuning of parameters such as sound absorption, transmission, reflection, frequency bandgaps, and wave direction. Adjustability is typically achieved through mechanical reconfiguration, electrical control, thermal variation, magnetic fields, fluidic systems, or smart materials such as piezoelectrics, shape-memory alloys, and elastomers.

Key capabilities include adaptive noise reduction, reconfigurable sound insulation, frequency-selective filtering, wave steering, and acoustic cloaking. By modifying internal geometry or material properties, adjustable acoustic metamaterials can target different frequency ranges without physical replacement.

These materials have growing importance in architectural acoustics, aerospace and automotive noise control, ultrasound imaging, vibration isolation, sonar systems, and wearable or smart sensing technologies. Their ability to respond intelligently to changing acoustic environments makes them essential for next-generation smart acoustic devices and adaptive sensing systems.

Blockchain Integrate in Metaverse Development The metaverse is a digital universe where people can communicate, play, work, and wander using 3D technology. It is similar to a virtual reality with aspects of real life incorporated on the internet. One question that comes to mind is how this universe is created. Three of the major components bringing the metaverse to reality are Augmented Reality (AR), Virtual Reality (VR), and Blockchain. What Is Metaverse Development? Metaverse development is the process of creating virtual worlds where people can interact, work, play, and socialize using technologies like AR, VR, and blockchain. It involves building 3D environments, digital avatars, and secure systems that support real-time interaction and ownership of virtual assets, creating immersive experiences that connect the physical and digital worlds. 1. What Does Augmented Reality (AR) Do? AR (Augmented Reality) Places digital items such as pictures, sounds, or animations on top of the phys...

Quantum sensors for GPS-free orientation Along each of the three axes of measurement, a mechanical accelerometer is attached to the reference mirror of the atom interferometer, resulting in a classic/quantum hybridization that permits continuous measurement of acceleration with ultralow bias. Measurements of the three vector components are used to determine the acceleration vector, in any direction. The sensor is secured to a rotatable platform for demonstrating measurements from various angles. Credit: iXAtom How can we navigate airliners or allow military vehicles to stay on course without GPS or satellite signals? This is a problem for which quantum inertial sensors offer a solution. Harnessing quantum technology, they can take ultrasensitive measurements of acceleration in three dimensions, and in any orientation. 1st Editional of International Research Awards on Sensing Technology | 23-24 Jan 2023 | India Abstract Submission:  https://x-i.me/gaycon Award Nomination:  h...

Image
  🔍 General Description Fiber sensing refers to the use of optical fibers as sensors to detect changes in temperature, pressure, strain, vibration, chemical composition, or electric/magnetic fields . These sensors leverage changes in light propagation within the fiber to sense and measure environmental or structural conditions in real-time. 🧠 Technical Description Fiber optic sensors work by transmitting light through a glass or plastic fiber and analyzing how the light is altered due to external perturbations. These changes may affect intensity, phase, polarization, wavelength, or transit time of the light, depending on the sensing mechanism (e.g., Bragg grating, interferometric, or distributed sensing techniques). 🏗️ Applications Description Fiber sensors are widely used in: Structural Health Monitoring (bridges, tunnels, dams, buildings) Energy Sector (pipeline leakage detection, geothermal sensing, wind turbine monitoring) Aerospace and Defense (vibrati...
