Self-heating is a problem to consider for Ultrasound Imaging probes. Since the probe is in contact with the skin, it’s necessary to find a solution to lower the front face temperature in order to avoid patient discomfort, even at the most demanding operating condition. One solution ... 詳細を見る
MEMS Pressure sensors work on the principle of mechanical bending of thin diaphragm under applied load over diaphragm area. The sensitivity of diaphragm is crucial to efficiency of the sensor. It is defined as the increase in deflection of diaphragm as a result of increase in pressure ... 詳細を見る
A recurring problem, in heat assisted magnetic recording is the build-up of thermal energy in the near-field transducer leading to NFT deformation and the cessation of operation. A mechanism to dissipate this excess heat in the NFT without greatly effecting its’ plasmonic response is ... 詳細を見る
Position sensors have several applications in the automotive sector. Some of the common examples include automatic gear shifter module, seat position adjustment and accelerator-pedal position modules etc. Because of extreme weather condition, such as dust, humidity and moisture and ... 詳細を見る
A three-dimensional finite element model, based on the linear field equations for superimposed small vibrations onto nonlinear thermoelastic stressed media given by Lee and Yong, was developed. This method involves solving the thermal stress and piezoelectric model with geometric and ... 詳細を見る
When placing a loudspeaker in a cabinet, standing waves inside the cabinet affect the frequency response with ripples. This peaks and dips due to pressure cancellation inside the cabinet have an effect on the diaphragm and generating sound out from the vents. If it was in a condition of ... 詳細を見る
High frequency ultrasound (100-1000 MHz) has been used in microscopy since the 1970s. The main imaging component, the acoustic lens, is commercially available. The resolution, working distance, and focal length depend on the structure of a lens, which is unique for each produced lens. ... 詳細を見る
Finite element (FE) modelling of ultrasonic propagation using COMSOL Multiphysics® simulations can be used to create images of waves. Unfortunately, in time-stepping solutions, it is possible for numerical instabilities to grow large and dominate the solution adversely. Any design of ... 詳細を見る
Capacitive MEMS sensors offer high spatial resolution, sensitivity and good frequency response. In this paper, we present a circular membrane capacitive MEMS device that finds use both as capacitive micromachined ultrasonic transducer (CMUT) and pressure sensor. The MEMS device is first ... 詳細を見る
Daily application of a low intensity pulsed ultrasound (LIPUS) regimen has been shown to have positive effects on bone fracture healing. Although LIPUS treatment can induce cellular responses supporting bone repair, the underlying mechanisms are not well understood. Further in vitro ... 詳細を見る
