Solid-State Microfluidics with Integrated Thin-Film Acoustic Sensors
ACS Sensors, 2018For point-of-care applications, integrating sensors into a microfluidic chip is a nontrivial task because conventional detection modules are bulky and microfluidic chips are small in size and their fabrication processes are not compatible. In this work, a solid-state microfluidic chip with on-chip acoustic sensors using standard thin-film technologies ...

Use of Solid-State Acoustic Transducers in Communications
The Journal of the Acoustical Society of America, 1971Semiconductor and solid-state devices have been used extensively to measure and generate stresses and stress waves in solids, liquids, and gases. Semiconductor devices have been used as strain gauges to measure strains and to respond to acoustic pressures. p-type silicon has a guage factor of over 100 times that of a metallic strain gauge. By using the

ENGINEERING ACOUSTIC WAVE ON SOLID STATE QUANTUM MATERIAL
2022Solid state spin is a rapidly developing system for quantum sensors and computers. With the development of fabrication technology, since 2013, microelectromechanical systems (MEMS) technology began to be integrated with mechanical strain coupled to the spin system, instead of a traditional microwave antenna. Subsequently, the ability of quantum control

Density modulation of a solid-state plasma using acoustic pressure
2013 19th IEEE Pulsed Power Conference (PPC), 2013We are studying the plasma density response with pressure in indium antimonide (InSb), with the goal of developing a solid-state pressure gradient transducer [1]. We use intrinsic InSb, where the free carrier concentration depends only on the energy band gap and temperature.

Scanning acoustic microprobe analysis for testing solid state materials
Materials Science and Engineering: A, 1989Abstract A survey of analytic techniques for subsurface inspection by means of acoustic reflective microscopy is presented. The measurement of the acoustic material signature is carried out using a computer-assisted scanning acoustic microscope operating at frequencies between 100 and 400 MHz.

Surface Acoustic Waves in Solid-State Investigations
1989The continuously growing interest in surface acoustic waves (SAWs) in the last decade arises from the fact that they form the basis of numerous signal processing devices (delay lines, frequency filters, resonators, convolvers, etc.) and because they can be used for studying thin films and surface properties of materials as well as for constructing ...

Parametric excitation of acoustic waves in piezoelectric solid state magnetoplasma
Physics Letters A, 1979Abstract Absolute instability of the acoustic wave (excited parametrically) has been explored on the basis of the Bers and Briggs criterion in the presence of a large transverse static magnetic field. In the magnetoplasma threshold the electric field decreases to about 0.4 times the value at zero magnetic field.

Steady-state acoustic reflectometry for the reconstruction of solid cylindrical cavities
Proceedings of the Second Joint 24th Annual Conference and the Annual Fall Meeting of the Biomedical Engineering Society] [Engineering in Medicine and Biology, 2002Acoustic pulse reflectometry has been used in the past for the indirect determination of the cross-section area vs. distance function describing the geometry of solid cylindrical cavities such as the upper airway tract. Excitation pulse bandwidth, noise and system losses are usually the main experimental issues and sources of reconstruction error in ...
