We might need new types of chip designs for the internet of things


If we’re going to embed chips into roads, bury them in fields and even slap them on produce at the grocery store, we’re going to have to dump the battery. They are expensive, bulky, require changing and can also leak toxins into the environment. And while many people are focused on how to best to power these future sensors, the chip architecture firm ARM(s armh) is thinking about how to build chips for sensors that harvest their own energy.

Maybe these sensors are gathering power from RF signals in the air, kinetically, or even through a chemical reaction that they are built to recognize and report. No matter how they gather the energy, if they can’t store it then the way the chips use that power may have to change. At least that’s what Mike Muller, the CTO of ARM, told Peter Clarke of EETimes last week. In
