The first requirement for designing self-powered wireless products was the ability to scavenge energy from the surrounding environment. Energy harvesting has been around for centuries: after all, windmills, tide mills and water turbines have been extracting raw energy from the environment to generate power since ancient times. The second requirement was to use this energy for efficient communication between different devices. Again, likely solutions have been assumed for some time, with low power radio systems such as Bluetooth or Wi-Fi.
