Abstract
Piezoelectric energy harvesters scavenging energy from
the environment have been a promising solution to satisfy
the increasing power demand in wireless sensor nodes.
Power conditioning circuits for piezoelectric energy harvesters are a burgeoning technology widely disclosed in literature since 2001; however, there is still no complete overview
available, which exhaustively describes the cutting-edge
status of the research on power conditioning for piezoelectric energy harvesters. This paper aims at providing a more
complete review on the state-of-the-art piezoelectric energy

harvesting interfaces. a systematic categorization of the
piezoelectric energy harvesting approaches is presented,
based on the qualitative working principle, adopted control
scheme, and employed components. The presented power
conditioning interfaces are commented and discussed in
detail, addressing the strengths and weaknesses based
on the achieved results. Furthermore, this paper performs
a critical comparison of state-of-the-art techniques by employing seven criteria to evaluate the performance of an energy harvesting system. The observed trend in this field is to
design harvesting rectification schemes by employing maximum Power Point Tracking (mPPT) algorithms to achieve
a high Power conversion efficiency (Pce) and, resonant
rectification techniques to harvest efficiently energy from
wide-band excitations.
