Molecular Communication provides a solution for scenarios where
conventional technologies for data transmission are not feasible due to
energy or size constraints. The development and characterisation of
sensor devices for information particles as receivers is an essential
step to realising Molecular Communication setups. In this work we will
present a new device for sensing of magnetic nanoparticles using a
capacitor to detect changes in permittivity. The sensor was evaluated
regarding sensitivity and a data transmission scenario in a testbed and
compared to an inductive sensor. The new sensor device has a
significantly higher sensitivity than the reference sensor, allowing for
the use of less information particles when transmitting data. However,
the impulse response is wider as magnetic nanoparticles are held in the
electromagnetic field of the receiver's capacitor.
