First, achieving the desired movement from a piezoelectric crystal
often requires large voltages, though mercifully at low DC currents.
The performance of the wire sensor is almost comparable to that of a conventional piezoelectric crystal
The lengths of the piezoelectric crystals
determine the fundamental frequency of oscillation.
A variation of this device uses piezoelectric crystal
switches in place of mechanical switches.
The piezoelectric crystal
is key to the design of neural dust.
A piezoelectric crystal
vibrates when an alternating voltage is applied to it, and almost all of the energy given to the material is converted into mechanical motion.
The results obtained in this study," the researchers say, "demonstrate that a piezoelectric crystal
coated with a specific antibody could be used as an analytical tool in gas-phase analysis.
Forces from the sensing vane are transferred via the torque tubes to the piezoelectric crystal
sensors, which are placed in the wall of the flowmeter out of the flow stream.
The FBG fiberoptic technology is far superior to traditional sensor technologies that use a transducer (a piezoelectric crystal
or thermocouple), and produce weaker signals.
E[acute accent]The basic SAW device is a thin metal film structure deposited on top of a piezoelectric crystal
substrate with no power supplies.
transform pressure or motion into electricity when they are compressed or vibrated; phonograph needles are one common example.
The equipment falls under Chapter 85 of the GST Rate Schedule for Goods and include diodes, transistors and similar semiconductor devices, photosensitive semiconductor devices including photo voltaic cells, light emitting diodes ( LED) and mounted piezoelectric crystals
