that the designed piezoelectric wind harvester system with an efficiency of
72% is able to power a wireless RF transmitter load to transmit five digital
12-bit encoded data words to the receiver end during one wireless transmis-
sion. The proposed piezoelectric-based wind harvester can be used in appli-
cations that need to detect wind speed beyond a certain threshold level, for
instance for early warning of a storm. When the ambient wind speed is be-
yond the preset value, a 12-bit digital signal will be transmitted in a wireless
manner to the base station to set off the warning siren.
