These materials possess a unique property known as the piezoelectric effect, where mechanical pressure or vibrations are converted into electricity, and vice versa.
How do piezoelectric crystals work?
Piezoelectric crystals have a specific internal structure where the positive and negative charges are not symmetrically distributed. When pressure or vibration applies to the crystal, this internal structure gets distorted, causing the separation of charges and generating a voltage across the material. Similarly, applying an electric field to the crystal can cause it to deform, generating mechanical vibrations.

Types of piezoelectric crystals:
Nature and science have gifted us with a diverse set of piezoelectric materials, each with its own characteristics and applications:
- Natural crystals: Quartz, Rochelle salt, and topaz are some of the earliest known piezoelectric crystals. While offering good sensitivity, they can be fragile and have temperature limitations.
- Ceramic materials: Lead zirconate titanate (PZT) is a widely used man-made ceramic, providing high piezoelectric coefficients and versatility. Other ceramics like barium titanate, lithium niobate, and sodium tungstate find applications in specific niche areas.
- Polymer films: Polyvinylidene difluoride (PVDF) is a flexible and lightweight piezoelectric polymer, often used in sensors and transducers. Other polymers like polymethyl methacrylate (PMMA) are being explored for their unique properties.
Applications of piezoelectric crystals:
The fascinating versatility of piezoelectric materials fuels innovation in various sectors:
- Sensors: Pressure sensors in smartphones, microphones in hearing aids, and accelerometers in fitness trackers all rely on piezoelectricity to sense movement and vibrations.
- Transducers: Ultrasonic transducers for medical imaging, sonar systems for underwater navigation, and actuators for haptic feedback in devices utilize the ability of piezo crystals to convert electrical energy into mechanical vibrations.
- Energy harvesting: Piezoelectric energy harvesting devices can convert wasted mechanical energy from footsteps, traffic vibrations, or wind into usable electricity, powering small devices or contributing to sustainable energy solutions.
- Medical applications: Piezoelectric crystals are used in ultrasonic surgical tools, nebulizers for respiratory therapy, and even some blood pressure monitors.
