Researchers Develop A Smart Glass Which Can Charge A Smartphone
The research and development team at Georgia Institute of Technology has worked to develop a color-changing glass which can create electrical charges, sufficient enough to power a smartphone.
The main objective behind this development was to make normal-use windows provided with triboelectric technology – enabling static charges to store electrical energy as a result of contact between two material surfaces.
Normally windows/wind shields come in contact, mostly, with wind and rain droplets. So both these mediums were used in the development process to come get the best results. Nano-sized generators were built in order to utilize positive charges in the raindrops. This happens as a result of raindrops interacting with air and finally touching down on the windshield.
Second layer of solution was made by sandwiching two charged plastic sheets with small springs. Due to air pressure, the sheets are pushed against each other producing electrical current for the experiment.
The two layers combined, hence, researchers were finally able to render a glass that is clear to start with but the color transitions to blue tint with the passage of time.
Quantitatively speaking the whole process is capable enough to produce 130 milliwatts of electricity enough to charge an average smartphone’s battery. This is considered to be a major benefit for wires network providers as it provides a reliable external power source. This successful experiment also lead to the invention of triboelectric nanogenerator (TENG) that works to produce electricity by converting atmospheric mechanical energies.
A complete description on the development and functionality of the team’s work can be found published on the journal of ACS Nano. It also mentions suitable practical applications of the smart glass, something of particular interest for those who vouch for things done outside the box.
