Welcome back to the monthly bloghop – We Are The World Blogfest. It is a time to share snippets of good news happening around the world in an effort to diminish the impact of negative news.
There are many electronic devices these days and more and more wearable devices. The impact of the batteries required to charge those devices is another one of those dirty little secrets many people are either ignorant of or choose to ignore in favor of the convenience of the technology.
Both the manufacture and the disposal of these batteries are neither sustainable nor are they good for the environment.
There is good news on the horizon, however. Engineers from the Nanyang Technological University in Singapore have developed a tiny bandage thin battery that is charged off of ‘sweat’. This battery can discharge 20 hours of electricity from 2 ml of perspiration.
During testing, a volunteer was able to generate a voltage of 4.2 V and an output power of 3.9 mW. That’s impressive. Imagine a battery powered by perspiration rather than one damaged by perspiration.
