Small wake-up receivers could extend IoT sensor life

One of the potential hindrances to ubiquitous Internet of Things (IoT) take-up is related to how one should power the possibly billions of tiny sensors promised over time. Can one expect a homeowner to change out a hundred or so coin batteries every few years in, say, a networked system, for example? That could get old fast.
