EDN provides engineers and engineering managers with in-depth design features and deep technical information on microprocessors and other digital ICs, analog ICs, ASICs, computers and software, computer peripherals, test and measurement, components, power sources, interconnections and packaging, and much more. EDN also explores important application areas such as computers, communications, embedded, industrial, and consumer electronics.

Advances in energy-storage technology power wireless devices Energy harvesting relies on intermittent energy sources and requires energy storage, such as a capacitor or a battery. New improvements in these components point toward smaller, longer-lived wireless sensor nodes, but a long-lived primary battery may be your simplest energy-source choice.
