Piezoelectric accelerometers are one form of accelerometer that measures acceleration on the surface by using mechanical shock, vibrations, and other factors. To monitor dynamic variables in mechanical impacts, including vibration, acceleration, and mechanical shocks, these devices rely on the piezoelectric effect of specific materials.
For example, they convert mechanical and motional energy into electrical energy proportionate to the applied acceleration in order to transmit electrical signals and measure conditions, quantity, and property.
In most cases, piezoelectric accelerometers have integrated signal-conditioning circuits that take the raw voltage outputs from the accelerometer’s piezoelectric sensors and transform them into signals that are more dependable and can be analysed by instruments.
The Global analogue piezoelectric voice accelerometer market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
The VA1210 is a second-generation analogue piezoelectric smart voice accelerometer, introduced by Vesper. The VA1210 has better voice pickup sensitivity (+17 dB) and SNR (+6 dB).
The introduction of new intelligent Wake-on-Voice and Hardware Voice Activity Detection functions is another feature.
China was the first country to release the FATRI MEMS piezoelectric speech acceleration sensor. The recently introduced MEMS piezoelectric speech acceleration sensor is capable of picking up high-frequency broadband voice in addition to outputting single-ended analogue and efficiently filtering out background sound.
It also has a straightforward structure, a compact dimension, is lightweight, and allows for easier installation.
