Scientists are currently studying how to tap the energy naturally created by people's bodies - such as movement, heat and sound - to power devices without the need to change batteries. Without the hassle of carrying these huge power banks with us all the time. The researchers said that the implant is small enough that it could be placed in one's ear. Experts also predict that the device for bioenergy harvesting could be available within the decade. Imagine if we can charge our smartphones through our ear? Science, you did it again.
