Silicon Nitride Corrugated Membrane with High-Width-Aspect-Ratio for MEMS Microphones
Micro-Electro-Mechanical Devices such as acoustics sensors, finger print sensors, tunable capacitors etc. are widely used in commercial applications. The pressure sensors use membranes which deflect upon applied pressure load. The most important aspect of any pressure sensor is its ... Read More
3D Thermo-Acoustic Modeling of a Piezo Transducer for Directed Interstitial Ultrasound Ablation
Thermal ablation is a treatment option in oncology that can be used to target primary and metastatic cancers. In this approach, high temperature heating is administered at the target tumor site to induce coagulative necrosis of malignant cells. One minimally invasive method for ... Read More
Modeling the Directional Response of Slim Height Channel Speakers
Modern home audio products are starting to feature dedicated upward firing height channel speakers, which are a combination of unique physical speaker design and special signal processing, to reproduce audio as if the sound source is located in the ceiling. Due to slim form factor design ... Read More
Sound Generated by Quadrupole Near Object
Aerodynamic sound is generated by unsteady fluid motion and enhanced when the flow becomes turbulent. For example, drone is loud because the ambient air is stirred by their propeller to get lift and movement and the air becomes turbulent. Reduction of aerodynamic noise is an important ... Read More
Simulation of a Piezoelectric Catheter-Based Acoustic Ablation Device
Thermal ablation driven by an acoustic heat source has tremendous potential for the treatment of diseased tissue. In many applications, such as treating tumors in the liver, bulk removal of tissue is required, and thermal ablation can reliably cause necrosis for a relatively large tissue ... Read More
Acoustic Metamaterial Lens and Simulation-Based “Meta-Library”
Metamaterials are composites of subwavelength structures that can be engineered to affect the propagation of a wave in specific ways as it travels through the material. While metamaterials can be used with any type of wave, they are most commonly found in electromagnetic waves. However, ... Read More
The Influence of Sensor Technology on the Performance of Acoustic Leak Detection for Water Networks
As water networks around the world age, leakage and water main breaks are becoming an increasing problem. Leakage rates of 10-30% are typical in North America, and most cities suffer from hundreds (or thousands) of water main breaks every year. Echologics has developed the EchoShore ... Read More
Modeling of 3D Cilium Mechanics in COMSOL® Using Beam Physics with Linear Extrusion Coupling
Cilia are slender micro-organelles (200 nm diameter, 10 µm long) that generate propagating waves to propel cells or move fluid. The cytoskeletal structure of the cilium (the axoneme) consists of 9 outer microtubule doublets and 2 central microtubule singlets. Outer doublets are connected ... Read More
Analysis of Powertrain Mounting System
Powertrain mounting systems are subjected to varying degrees of continuous dynamic loads resulting into unbalance of forces at their mount locations. These forces contribute significantly towards noise, vibration and harshness signatures in the vehicle cabin and has strong negative ... Read More
Design Analysis and Topology Optimization of Vertical Machining Center Spindle Head Structure
Optimal design and development of a machine tool structures have great influence on the precision of the machine tool's operations. The present work involves the design optimization of cast iron made CNC Spindle head for minimum overall compliance and the minimum weight of structural ... Read More
