UOther electronic devices used in water treatment and related
process technologies that can be powered with inductive coupling
are electrodes, ultrasound transducers and sensors. Inductive coupling
makes it possible to have mobile sensors for water treatment
systems similar to the endoscopic capsules which are investigated
by Carta et al. [12] who showed that an endoscopic capsule can
be powered by inductive coupling, be self-propelled and steerable
[13]. Using a 3D coil to receive power, independent of the
orientation of the receiving coils inside the transmitting coil and
wireless data transmission, creates the possibility for sensors with
many potential applications [14]. The possibility of having a wireless
sensor network inside reactors can greatly improve the process
monitoring and control of chemical reactors
