TY  - JOUR
AB  - The use of energy harvesting for powering wireless sensors is made more challenging in most applications by the requirement for customization to each specific application environment because of specificities of the available energy form, such as precise location,  direction  and  motion  frequency,  as  well  as  the  temporal  variation  and unpredictability of the energy source. Wireless power transfer from dedicated sources can overcome these difficulties, and in this work, the use of targeted ultrasonic power transfer as a possible method for remote powering of sensor nodes is investigated. A powering  system  for  pipeline  monitoring  sensors  is described  and  studied experimentally, with a pair of identical, non6inertial piezoelectric transducers used at the  transmitter  and  receiver.  Power  transmission  of  18  mW  (Root6Mean6Square) through  1  m  of  a 118 mm  diameter  cast  iron  pipe,  with  8  mm  wall  thickness  is demonstrated. By analysis of the delay between transmission and reception, including reflections from the pipeline edges, a transmission speed of 1000 m/s is observed, corresponding to the phase velocity of the L(0,1) axial and F(1,1) radial modes of the pipe structure. A reduction of power delivery with water6filling is observed, yet over 4 mW of delivered power through a fully6filled pipe is demonstrated. The transmitted power and voltage levels exceed the requirements for efficient power management, including rectification at cold6starting conditions, and for the operation of low6power sensor nodes. The proposed powering technique may allow the implementation of energy autonomous wireless sensor systems for monitoring industrial and network pipeline infrastructure.
