Scientists uncover advanced manufacturing strategies for piezoelectric and triboelectric tactile sensors

Piezoelectric and triboelectric tactile sensors are designed to convert mechanical stimuli into electrical signals, making them critical components in intelligent systems. Piezoelectric sensors leverage voltage generation through mechanical stress in non-centrosymmetric materials, such as quartz and polyvinylidene fluoride (PVDF), while triboelectric sensors operate on contact-induced charge transfer. Both sensor types offer unique advantages, including self-powered functionality and high sensitivity, but also face challenges, such as material brittleness and environmental limitations. A team of researchers led by Professor Hanjun Ryu from Chung-Ang University, South Korea, has introduced novel manufacturing strategies to overcome these limitations. The team's paper is published in the International Journal of Extreme Manufacturing.

The more I learn about very basic ways to generate (admittedly very low) amounts of electricity using basically nothing the more pissed I am that like 17 people are insistent on sending the whole world to hell because god forbid they make less than $87 trillion every minute

Energy: Wasted Styrofoam Generates Power through Static Electricity

Researchers from the Royal Melbourne Institute of Technology (RMIT) and Riga Technical University (RTU) have introduced an innovative method to generate electricity from polystyrene, a widely used but environmentally persistent material. This plastic-based foam, known for its resilience, often takes up to 500 years to decompose and accumulates significantly in landfills, with global production…

Bots getting off by rubbing themselves with soft cloth... building up static electricity makes them feel all tingly until they finally overload.

Fun fact: the scientific name for the force that causes static electricity is called the triboelectric effect

[rlyehtaxidermist]

i feel like i say this every semester but it is really really really funny to me that we start out every introduction to physics units with gravity for mechanics and the triboelectric effect for electricity and magnetism, which are by far the two most unexplained things in those respective groupings of physical phenomena

I like having my dihydrogen monoxide in a glass. Rubber or latex cups are lower on the triboelectric series which makes it so they hold more electrons, more electrons mean more energy, some of which is heat. Metal cups don't work either because, since it is conductive, meaning electrons flow through it, more electrons means more energy, some of which will be heat energy. Therefore, you want a glass at a temperature of 5.870987902438907 degrees, since at that specific temperature, the surrounding dihydrogen monoxide gas, condenses on the glass. The glass must be a vertical, narrow, tall glass. You need to use tall glasses so that dihydrogen monoxide is less likely to seep out of the glass. Some people prefer horizontal, broader glasses but that has been proven to optimize heat flow, which results in liquid dihydrogen monoxide, at a temperature of approximately 8.31247861289743019834 degrees. If you leave a Hori glass distilled for about 27.798204719028734098123779124801327 minutes. The condensed dihydrogen monoxide on the outside of the glass eventually forms bigger droplets that are affected by gravity, therefore earning kinetic energy, which will then be converted to heat energy that affects your glass. To counter this, beginners in liquid dihydrogen monoxide consumption can get glasses with many ridges and "designs".A common mistake amongst beginners is to add carbon dioxide into their dihydrogen monoxide at a ratio of about 4:96 but the real experts will tell you, the less carbon dioxide in your dihydrogen monoxide concoction, the better. Carbon dioxide ruins very precise steps that have been taken to ensure your dihydrogen monoxide is of the greatest quality, and carbon dioxide can displace oxygen in your lungs' alveoli, meaning carbonated dihydrogen monoxide can kill you.The PH of your dihydrogen monoxide should be 7 according to the usgs.gov official website, however many studies and experiments later, the secret dihydrogen monoxide society has decided 6.32984679184236710293870298346712390868917234576238917608932740917409123647908740129738489321460945612935701812569872345687923162389746892734568791246093816817934012346190501647894278014934256782349 is the perfect PH.One problem though, you may want to add other components to your dihydrogen monoxide concoction.

I have tap water and vodka take it or leave it

[materialsscienceandengineering]

Inspired by the classic drinking bird toy, scientists in Hong Kong and Guangzhou, China have developed an engine that efficiently converts energy from water evaporation into electricity to power small electronics. The device produces energy outputs exceeding 100 volts -- much higher than other techniques that generate electricity from water -- and can operate for several days using only 100 milliliters of water as fuel, according to a study published March 14 in the journal Device. "The drinking bird triboelectric hydrovoltaic generator offers a unique means to power small electronics in ambient conditions, utilizing water as a readily available fuel source," said Hao Wu, a professor at South China University of Technology and the first author of the study. "I still feel surprised and excited when witnessing the actual results."

Pretty boy pretty boy pretty boy pretty boy pretty boy did someone say pretty boy. I have been summoned🙋‍♀️🫠

-pretty boy anon

as a term of endearment it just suits ava and beatrice so well.

thinking of ava pushing her fingers through bea’s hair right after she cuts it. bea leaning in and whispering to her about static electricity as the fresh-cut strands fall at her feet, cling victoriously to the sleeves of her hoodie.

ava calling her pretty boy, then, and leaning so so close as beatrice avoids her eyes, blushes. low voiced into the space between them awry facts about ozone cracking, an imbalance of atoms, their charge, how a touch can change you, how it’s triboelectric - and bea wondering aloud if that word comes from tributary, getting ava’s fingers tangled up in her hair where it’s left longer on top.

the brush of air, breath, wind over short sides and telling ava how it feels aerodynamic to move when the hair is newly-disappeared.

and bea stepping light around the subject until one day ava’s trying on sunglasses in a store. it’s bright outside and they can’t afford anything in this place - the palpable press of ava’s fingers on the lenses, buffing them with her sleeve. tipping a pair of shades onto bea’s nose “see now you look like that girl you have a crush on in jurassic park”

“i do not have a crush on anyone from jurassic park”

ava slipping on a pair bea doesn’t know the name of - she knows so much but not this and it’s comfort light life to find herself thinking that ava would know, would tell her if she asked.

she doesn’t. just fixes the frames so they sit straight, whispers low under the blur of bodies around them, “i think we should keep these”

“they’re like, 200 euros bea.”

ten minutes later they’re breathless, bea slips the glasses out from the sleeve of her hoodie and ava’s saying you know there’s a whole commandment about stealing and bea

“what am i a nun?”

placing them on ava’s face like she’s anointing her, crowning her again, and saying low under her breath, “pretty boy” just to see ava stare at her through her shades, unable to hide the slight wobble that chases itself across her jaw

"What?"

"Jupiter's magnetosphere is the largest thing in the solar system. If the human eye could see it, it would appear two and a half times wider in the sky than the sun does."

"I knew that," she said, irrationally annoyed.

"Quotation is. Easy. Speech is. Not."

"Don't speak, then."

"Trying. To communicate!"

She shrugged. "So go ahead—communicate."

Silence. Then, "What does. This. Sound like?"

"What does what sound like?"

"Io is a sulfur-rich, iron-cored moon in a circular orbit around Jupiter. What does this. Sound like? Tidal forces from Jupiter and Ganymede pull and squeeze Io sufficiently to melt Tartarus, its sub-surface sulfur ocean. Tartarus vents its excess energy with sulfur and sulfur dioxide volcanoes. What does. This sound like? Io's metallic core generates a magnetic field which punches a hole in Jupiter's magnetosphere, and also creates a high-energy ion flux tube connecting its own poles with the north and south poles of Jupiter. What. Does this sound like? Io sweeps up and absorbs all the electrons in the million-volt range. Its volcanoes pump out sulfur dioxide; its magnetic field breaks down a percentage of that into sulfur and oxygen ions; and these ions are pumped into the hole punched in the magnetosphere, creating a rotating field commonly called the Io torus. What does this sound like? Torus. Flux tube. Magnetosphere. Volcanoes. Sulfur ions. Molten ocean. Tidal heating. Circular orbit. What does this sound like?"

Against her will, Martha had found herself first listening, then intrigued, and finally involved. It was like a riddle or a word puzzle. There was a right answer to the question. Burton or Hols would have gotten it immediately. Martha had to think it through.

There was a faint hum of the radio's carrier beam. A patient, waiting noise.

At last, she cautiously said, "It sounds like a machine."

"Yes. Yes. Yes. Machine. Yes. Am machine. Am machine. Am machine. Yes. Yes. Machine. Yes."

"Wait. You're saying that Io is a machine? That you're a machine? That you're Io?"

"Sulfur is triboelectric. Sledge picks up charges. Burton's brain is intact. Language is data. Radio is medium. Am machine."

"I don't believe you."

Energy Harvesting Material

Energy harvesting materials are substances or devices that can convert various forms of energy from the environment into electrical energy. These materials play a crucial role in the development of self-sustaining or autonomous systems that can power themselves by harnessing energy from their surroundings. Here are some common types of energy harvesting materials:
