Battery life is a consistent problem, but a pair of US scientists believe they have an answer and have raised US$12.3 million to test their theory.
Matrix Industries, co-founded by Akram Boukai and Douglas Tham, is aiming to raise another $5 million to market a smartwatch battery powered by body heat.
Matrix says its smartwatches are “powered by your body heat” and never have to be charged.
It has three energy-harvesting models that will start shipping in September and October, ranging in price from $139 to $179.
According to Matrix, as users exercise, their skin gets warmer, generating thermoelectric energy for the PowerWatch. It also tracks sleep, steps taken and calories burned.
