Scientists Have Successfully Transformed Stress Into Electricity
Swiss engineers created this new material which is flexible and generates electricity when it is subjected to stress

Wouldn’t it be nice if our everyday stresses can produce something useful–like electricity? Well, recently, scientists have created a new organic material which can turn material stress to electricity.

Researchers from Empa, the Swiss Federal Laboratories for Materials Science and Technology, created this new material which is flexible and generates electrical energy when it is subjected to stress.
In the future, it could be used as a sensor that could be integrated into clothing or implanted in the body to power a pacemaker.

The Piezoelectric Effect
This new rubber material is able to convert mechanical movements into electrical charges. The generated current comes from the internal polarization that changes when the rubber film is mechanically stressed.

This effect, which was discovered in crystals is currently used in various applications such as sound pick-ups on analog record players, like how the needles is guided through the grooves in the record to be able to generate mechanical vibrations. In a piezoelectric crystal, these vibrations will be converted into electric pulses, which will be amplified and converted into sound waves.

Empa researcher Dorina Opris with her colleagues have given elastomers (rubberized fabric) piezoelectric properties.

The Future Awaits😁


You could charge your own phone??
The Human Mobile Power Generator!!!

1. Hook me up!

2. LOL. No shit! Texas could have used these suits in the big freeze!

Possibilities are endless!

Wonder if this is has an IPO? 🤔

3. I bet this finds its way into wind energy generators

... that can produce electricity from wind-driven vibrations of a single vertical blade instead of huge rotating blades. You could put small versions almost anywhere.

4. Certainly could be applied to wind driven vibrations

I find this fascinating with endless applications for use in the future.

They mentioned medical uses, as for pacemakers.

It is pretty exciting!!

5. Nervous Harold looks forward to this development...

6. Rofl Harold's nerves produce enough stress to light up the whole house!

😄

8. Nope, that's a Canadian supermarket chain; the EMPA in the article is a Swiss research institute

"Empire Company Limited is a Canadian conglomerate engaged mostly in food retail and corporate investments. The company is headquartered in Stellarton, Nova Scotia. Empire Company also owns the Sobeys supermarket chain. The company was founded in 1963."

As an interdisciplinary research institute of the ETH Domain, Empa, the Swiss Federal Laboratories for Materials Science and Technology, conducts cutting-edge materials and technology research. Our research and development activities focus on meeting the requirements of industry and the needs of society, and thus link applications-oriented research to the practical implementation of new ideas in the areas of nanostructured, “smart” materials and surfaces, energy, sustainable building and environmental technologies as well as medical technology and solutions for personalized medicine.

ETH is a Swiss university - where Einstein studied: https://en.wikipedia.org/wiki/ETH_Zurich

The article in the OP is also a rewrite of a 3 year old phys.org article: https://phys.org/news/2017-11-flexible-material-electricity-stressed.html
