Combined with the additional sensing layer, the device can measure other environmental parameters, such as ultraviolet radiation and humidity, which have been previously explored, e.g., ref. However, in practice, the first a few harmonics are generally taken for the simplicity of calculation. All numerical simulations presented in this work are performed by the commercial software COMSOL Multiphysics (Pressure Acoustics module). An arbitrary waveform signal generator is used to generate a sinusoidal signal with a voltage amplitude of 5V and frequencies varying from 1 to 20kHz. Although the resonant frequencies are shifted with the applied bending strains, the SPLs are hardly affected, demonstrating their good performance under bending conditions. The other experimental details are identical to those in the flat condition. Notes on the Officer Positions. The main drawback of energy harvesting using the piezoelectric direct effect is that the maximum electric power is generated at the fundamental resonance frequency. Februar 2022.

The main drawback of energy harvesting using the piezoelectric direct effect is that the maximum electric power is generated at the fundamental resonance frequency. 4h reveal a normalized SPL value larger than ~17dB, which is higher than those of the other flexible loudspeakers reported in the literature5,34,35,37,41. 5a. Lett. Do the same for the other entries in the education section.} Working as a flexible acoustic wave sensor, its operating frequency is determined by the wave velocity and the wavelength of the IDE. Most titles listed below require a license to be purchased or require the user to be a member of the group that owns the software. To adapt broadband and bidirectional ambient vibration, this paper designs and compares two PVEHs of L-shaped beam and U-shaped beam through COMSOL simulation Technol. IEEE Trans. 5, 19 (2014). With a substrate thickness of 1500m, the fundamental frequency of the flexible loudspeaker is ~22kHz, and the performance in the frequency band below 20kHz is significantly deteriorated. Despite this, we recommend checking the downloaded files with any free antivirus software. The flexible loudspeaker using configuration 2 shows an SPL value that is ~3dB higher than that using configuration 1 and thus would be preferred in practical applications. Sens. We would like to show you a description here but the site wont allow us. Commun. The sound pressure was measured using a commercial microphone (AWA14403) and a preamplifier (AWA14600E) with a sensitivity of 15mV/Pa, which was placed 5cm away from the flexible loudspeaker.
