Abstract
State-of-the-art wireless sensor nodes are mostly
supplied by batteries. Such sys tems have the disadvantage that
they are not maintenance free because of the limited lifetime
of batteries. Instead, wireless sensor nodes or related devices
can be remotely powered. To increase the operating range and
applicability of these remotely p owered devices an electro-mag-
netic energy harvester is developed in a 0.13
ml o wc o s tC M O S
technology. This paper presents an energy harvesting system that
