On-glass piezoelectric sensors are most suitable for which type of glass?

On-glass piezoelectric sensors are most suitable for sheet glass due to their design and functional characteristics. These sensors operate by detecting vibrations caused by pressure or impact on the glass surface. Sheet glass, being uniform and relatively thin, allows these sensors to effectively pick up such vibrations without interference from other materials or structural anomalies.

Tempered glass, while strong, undergoes a treatment process that modifies its properties, making it less responsive to the types of vibrations that piezoelectric sensors are designed to detect. Bulletproof glass, which consists of multiple layers of materials to resist penetration, dampens vibrations significantly, thus reducing the effectiveness of on-glass piezoelectric sensors. Frosted glass has a texturized surface that disrupts the transmission of vibrations, further making it unsuitable for this application.

Therefore, sheet glass provides an optimal surface for the piezoelectric sensors to function effectively, allowing them to detect disturbances accurately.
