A method for modeling piezoelectric-based ultrasonic acoustic–electric power and data transmission channels is presented. These channels employ piezoelectric disk transducers to convey signals across a series of physical layers using ultrasonic wav

Measurements were obtained by sending high frequency acoustic waves through a reinforced concrete column. Past work involved through-wall digital communications and power delivery through metallic barriers; this paper extends that work to a reinforce

With acoustic-electric channels, it is possible to send data through metallic barriers at very high rates while also transferring power. However, some isolated sensing situations require a lower complexity solution that is both small in size and low-

Acoustic-electric channels can be used to send data through metallic barriers, enabling communications where electromagnetic signals are ineffective. This paper considers an acoustic-electric channel that is formed by mounting piezoelectric transduce

An ‘acoustic fiber’, analogous to optical fiber, is presented as a means of long-distance data and energy transfer. Low-loss axial guided waves are produced along a cable-like waveguide, which is composed of a solid core and a cladding layer, whe

Acoustic-electric channels have been used in the recent past to send power and data through thin metallic barriers. Acoustic-electric channels formed along a structure which are highly attenuative and nonreverberant could have potential applications

A robust chisel damper for quieting a jackhammer is presented. The noise produced from a jackhammer chisel is dominated by the ringing of the chisel moil resulting from impacts of the internal hammer against the end of the chisel producing airborne r

This paper gives a bandwidth and sensitivity analysis for a vibrating square beam angular-rate sensor. A skew-symmetric gyroscopic inertia matrix results from rotating about an axis orthogonal to the plane of a forced-vibration elastic system giving

A variational equation is derived for the in-plane and out-of-plane motions of a configuration composed of two rectangular and annular sector piezoceramic bimorph plates arranged in the shape of one half of a single tuning fork. The required variatio

The variational equations derived in Part 1 of this work are extended to include the superposed angular velocity by means of the Coriolis effect. The resulting equations enable a semi-analytic treatment for the calculation of the dynamic characterist
