	  abstract     = {We present methods for developing wireless and
traceable sensors for photobioreactors or photoreactors in general.
The main focus of application are reactors which are wirelessly
powered. Due to the promising properties of the propagation of
magnetic fields under water we implemented an inductive link with
an on/off switched hartley-oscillator as transmitter and an LC-tank
as receiver. For this inductive link we used a carrier frequency
of 298 kHz. With this system we performed measurements to
demonstrate the independence of the magnetic field from water
or salty water. In contrast we showed the strongly reduced range
of RF-transmitter-receiver systems at higher frequencies (433 MHz
and 2.4 GHz) in water and in salty water. For implementing the
traceability of the sensors, we performed measurements to show
the well defined orientation of the magnetic field of a coil. This
information will be used in future work for implementing an inductive
link based traceability system for our sensors.},
