Where Is Energy Harvesting?


With power management a top priority in sensor networks, why is energy harvesting—a proven technology with diverse energy sources—conspicuously absent from sensor designs that are the foundation of the Internet of Things? [getkc id="165" kc_name="Energy harvesting"] always has been a promising answer to the limits of battery power. The idea that a device can run for much longer periods o... » read more

Life Without Batteries Or Wires


By Ed Sperling In portable devices, low-power design has always been about stretching out the amount of time between battery charges or replacement. But the focus of current research throws that approach to the wind. The new goal is to get rid of batteries altogether and generate power using a variety of different mechanisms ranging from differences in temperature, the motion of waves, static... » read more
