Ask yourself this question. These days, do you really need a timekeeping device on your wrist? With mobile phones being able to perform the same function, albeit from our pockets, the concept of a watch seems outdated. What if, rather than keeping track of time, we were able to keep track of our stress levels and other emotions using a wearable device? Thanks to modern science and technology, we are closer than ever to making this a reality. Researchers have invented environmentally friendly wearables that can convert our stress into useful electrical energy. They contain thermoelectric chips, which essentially provide for the conversion of heat energy released by the body into electrical energy. These devices generate about 1 volt of energy per square centimeter of skin covered. The concept sounds like something straight out of the Matrix series, wherein a race of robots enslaves humans to produce energy. Scientists have previously experimented with similar thermoelectric wearable devices, however, these are stretchy, can heal themselves when damaged, and most importantly, are fully recyclable.
There are many interesting ways that a device like this could be used. Tech enthusiasts could use the electrical energy generated to power smartwatches, or to charge their phones. These could play a role in solving the pollution-related problems that traditional batteries pose. They also have the potential to be used as devices that provide useful insights into our stress levels. Imagine a wearable, that is dependent on the energy generated by stress, which would give you information about your stress levels, and suggest measures to alleviate it. In today’s fast-paced world, where people struggle with emotional stability, a device like this could be the one thing that could help us to keep our mental state in check.
“Just don't tell the robots,” the researchers said in a statement. “We don't want them getting any ideas.”
