piezoelectricity is defined as the electric polarization in a substance (especially certain crystals) resulting from the application of mechanical stress.

in other words, electricity generated within crystals or other solid objects from stress, pressure, friction, or vibration!

[ now skip to the end for the cool part ]

piezoelectricity can be applied to many different things, including sonar, car parts, medical devices, smart phones, lighters, inkjet printers, and wristwatches, to name a few...

quartz is probably the most common piezoelectric crystal. quartz crystals are composed of silicon and oxygen - these are polar, chemically bonded atoms with a partial positive charge on silicon and a partial negative charge on oxygen, creating a separation of these charges (dipole). at rest, these dipoles cancel each other out, but when placed under mechanical stress, the dipoles become asymmetrical, causing a net positive charge on one side and a net negative charge on the other. this is repeated throughout the entire crystal; opposite charges are collected on opposite sides or faces of the crystal and this is what creates the voltage necessary to generate piezoelectricity.

but wait! there's more!

some other piezoelectric crystals include:

topaz

tourmaline

natrolite

schorl

wulfenite

langasite

other piezoelectric materials:

lithium

rochelle salts

ceramics

lead zirconate titanate

bone

enamel

dna

collagen

sucrose

the magic of it all:

quartz can be useful for just about any magical endeavor and is often seen as the "universal" crystal because it has so many uses

cleansing, charging, catalyzing, healing, channeling energy, amplifying energy, protection, warding, and divination to name a few.

one of the primary applications for electric crystals [namely quartz] in my practice is charging. i have an affinity for clear quartz and use it often so you can find it all over my altar, passively keeping things charged for later use and actively powering spells when i cast them. as natural batteries, quartz crystals also make for a wonderful centerpiece in a crystal grid.

i think the coolest thing about this phenomena is that quartz being described as a universal charging stone is actually evidence based - quartz crystals are proven to be capable of generating electricity, thus making them literal batteries for spellwork.

if you were skeptical, here's a video of me demonstrating the piezoelectric properties of raw quartz. :)

this will grind down and ruin your crystals, all while generating heat and breaking off bits in the process, so keep that in mind if you decide to try this at home - wear protective eye gear and heat safe gloves!

Scientists have long been fascinated by the formation of gold nuggets, often found nestled within quartz veins. New research led by Monash U

"Scientists have long been fascinated by the formation of gold nuggets, often found nestled within quartz veins. New research led by Monash University geologists suggests that the process might be even more electrifying than we previously thought—literally.

Gold nuggets, prized for their rarity and beauty, have been at the heart of gold rushes for centuries.

The study is led by Dr. Chris Voisey from the Monash University School of Earth Atmosphere and Environment and will be published in Nature Geoscience."

"The research team tested a new concept, piezoelectricity. Quartz, the mineral that typically hosts these gold deposits, has a unique property called piezoelectricity—it generates an electric charge when subjected to stress. This phenomenon is already familiar to us in everyday items like quartz watches and BBQ lighters, where a small mechanical force creates a significant voltage. What if the stress from earthquakes could do something similar within the Earth?"

""The results were stunning," said study co-author Professor Andy Tomkins, from the Monash University School of Earth, Atmosphere and Environment.

"The stressed quartz not only electrochemically deposited gold onto its surface, but it also formed and accumulated gold nanoparticles," he said.

"Remarkably, the gold had a tendency to deposit on existing gold grains rather than forming new ones.""

Why you don't want 'phantom energy' on a spacecraft

You may not have heard of piezoelectric materials, but odds are, you have benefitted from them.

Piezoelectric materials are solid materials—like crystals, bone or proteins—that produce an electric current when they are placed under mechanical stress.

Materials that harvest energy from their surroundings (through light, heat and motion) are finding their way into solar cells, wearable and implantable electronics and even onto spacecraft. They let us keep devices charged for longer, maybe even forever, without the need to connect them to a power supply.

But for these energy harvesters to work effectively, we must know exactly how much energy they can produce.

Now, for the first time, using a simple signal processing technique, our team has shown that electrical signals used to benchmark piezoelectric materials include electro-static (or phantom) energy.

Necklace #1: chrysocolla with obsidian, quartz, and selenite

Primary use: chronic pain, especially that worsened by negative emotional influence and/or overstimulation (see also "central sensitization)

Chrysocolla is known for assisting chronic pain patients with pain levels, thought to be due to the rich presence of copper which is famous among rheumatics for musculoskeletal support, and among Chinese medicine practitioners for channeling and strengthening of Chi.

Obsidian, also known to some as volcanic glass, is famous around the globe for its energy-transmuting properties and grounding from negative influence. The application for central sensitization is the blocking and deflection of harmful energetic frequencies which overload the nervous system, keep the fight-or-flight response locked in the "on" position, and close an endless loop of overstimulation and pain.

Clear quartz is known as the master crystal because not only is its piezoelectric frequency an all-purpose balancing frequency, it also amplifies the piezoelectric frequency of other crystals. Think of it as a "driver" for other crystals.

Selenite is widely regarded as a sort of Energizer battery for other crystals, needing next to no charging in and of itself. It too is a sort of amplifier for other crystals, but its main purpose is typically extending the life of piezoelectric charge, meaning the user has to charge the necklace less frequently. Selenite also has energetic cleansing properties, meaning that because its frequency is so strong and so high, lower-frequency charge is overtaken and other stones (and the wearer) are "cleansed" from the harmful resonance.

Hejkin

[Originally, hej-kin was hyphenated, but the hyphen was dropped in 4e. 4e also gave these little guys electrical powers. This may seem odd in the usual 3e/PFRPG paradigm of “air = electricity, earth = acid”, but it makes sense to me. Crystals generate electricity, after all.]

Hejkin CR 1 NE Aberration This stunted creature has pointed ears, oversized claws on its hands and feet and a patchy, shaggy coat. Its body is distorted, as if some of the bones were too large and others too small.

Hejkins are strange earth-dwelling creatures, xenophobic and violent. They despise anyone and anything that disturbs solid rock, which they view as sacred. They live only in natural cave formations, typically around a water supply, and attack miners, stonemasons and any other entities that try to carve into the earth. Hejkins are awkward in motion, but surprisingly strong for their size. They never fight with weapons, instead using their claws and bursts of electricity. A hejkin can move through solid rock, but only slowly, which they use to escape from danger or gather reinforcements.

Hejkin society is theocratic, with a caste of priests that venerate beings of elemental earth, great old ones, and gods of monstrosity and deformity. These “priests” rarely have the cleric class—oracles and sorcerers are most common. Priests have the rare privilege among the hejkin of being allowed to go to the surface, which they do at night in order to read omens in the stars. Sunlight blinds the hejkin, but deals them no permanent damage. They are omnivores with a taste for insects and fungus. Hejkin value textiles and intricately carved wood as treasure, since neither of these things are common below ground compared to metals and minerals.

I’m not much for physics, but could piezoelectric tiles be used in cow farms to generate electricity? Since there’s guaranteed high traffic most of the time as the cows move around, plus given that cows are so much larger than humans the displacement they create in the piezoelectric material would be greater and could create more electricity (if I’m understanding the equations right)

Most attempts at using or studies into them I’ve seen are in places of human traffic, which also comes with loads of expense and energy consumption to install them, but putting them in a barn might not cause too much inconvenience and then the cows would generate the energy just going about their days.

A biological material developed by nanotech scientists can generate electric currents and voltage cleanly, using surrounding movements to charge up.

Two years ago, an international research group led by scientists from Tel Aviv University published a paper about this material – a molecule called Hyp-Phe-Phe. It resembles collagen, a protein whose strength and flexibility make it useful in many applications, but is much shorter and simpler.

Now, in a study published in Nature Communications, the researchers show that the new material shares another feature with collagen – piezoelectricity.

“Piezoelectricity is the ability of a material to generate electric currents and voltage as a result of the application of mechanical force, or vice versa, to create a mechanical force as the result of exposure to an electric field,” explained TAU’s Prof. Ehud Gazit.

“Most of the piezoelectric materials that we know of today are toxic lead-based materials, or polymers, meaning they are not environmentally and human body-friendly. Our new material, however, is completely biological, and therefore suitable for uses within the body.”

For example, a device made from Hyp-Phe-Phe could replace a battery in implants like pacemakers. Heartbeats, jaw movements, bowel movements, or any other movement that occurs in the body on a regular basis would charge the device with electricity to continuously activate the implant.

Fun fact about quartz. It has a ability called “piezoelectricity” It means, if you heat up or squeeze a certain gem enough, it will produce an electric charge! I don’t know why power companies aren’t using it, maybe it’s because it will damage the gem. Still, imagine the amount of electricity that piece of quartz can make!
