The technology is depending on an electrode integrated into a segment of the tire. When it comes into contact with the ground,
team used a toy car with LED LIGHTS. Engineers attached an electrode to the tires of the toy car
and watched the LED LIGHTS as the car was rolling forward and they flashed on and off as electrodes came with contact with the surface.
The friction was strong enough for the electrodes to harvest enough energy to power the lights,
which means that scientists confirmed the idea that wasted friction energy can be collected and reused.
Engineers also determined that the amount of energy harnessed is directly related to the weight of a car
captures harmful gas and weaves transistors into shirts and dresses. otton is one of the most fascinating and misunderstood materials,
and that is our world we can control cellulose-based materials one atom at a time. he Hinestroza group has turned cotton fibers into electronic components such as transistors and thermistors,
so instead of adding electronics to fabrics, he converts the fabric into an electronic component. reating transistors
and other components using cotton fibers brings a new perspective to the seamless integration of electronics
and textiles, enabling the creation of unique wearable electronic devices, Hinestroza said. Taking advantage of cotton irregular topography, Hinestroza and his students added conformal coatings of gold nanoparticles,
as well as semiconductive and conductive polymers to tailor the behavior of natural cotton fibers. he layers were so thin that the flexibility of the cotton fibers is preserved always,
ingestible electronics, which can diagnose and monitor a variety of conditions in the GI TRACT; or extended-release drug-delivery systems that could last for weeks
your next phone could be made of wood Engineers hunting for a way to make electronics more sustainable have hit on a novel invention-a semiconductor chip made almost entirely out of wood.
The idea is that instead of making chips from petroleum-based plastic, we'd be able to use cellulose nanofibril-a flexible,
"The majority of material in a chip is support. We only use less than a couple of micrometers for everything else,
"The result is based a bio chip, which is not only flexible enough to use in consumer electronics but an order of magnitude more environmentally-friendly."
"The chips are so safe you can put them in the forest and fungus will degrade it.
They become as safe as fertilizer, "said Ma. He added:""Mass-producing current semiconductor chips is so cheap,
and it may take time for the industry to adapt to our design. But flexible electronics are the future,
and we think we're going to be well ahead of the curve
