We present an improved version of a torsionally oscillating resonant pipe viscosity sensor. The new design offers the possibility to sense both, viscosity and density independently and at the same time. The first version of the sensor allowed only se

The dynamic behavior of an electrowetting-on-dielectrics (EWOD) actuation process can be linked to certain fluid properties of the actuated polar liquid droplet. After actuation, inertia will lead to droplet oscillations, where the contact angle asym

We present a method to design specific heater electrode distributions on substrates with high thermal conductivity such as sheet metal. The substrate is covered with a thin polymer insulation layer on both sides, which are, in turn, carrying screen p

We present a measurement system for the viscosity and density of a fluid featuring a permanent magnet as measurement body, which is levitated in an actively controlled magnetic field. The behavior of the system is illustrated using different measurem

In this contribution we present a minimum effort approach to sensors for physical quantities like, e.g., force, pressure, strain, and temperature without the need for cost-intensive lab equipment. Only adhesive tape, carbon black, some kind of cuttin

We investigated the vibration characteristics of the torsional oscillation mode of an earlier proposed resonant viscosity sensor based on vibrating pipes. To do so, the sensor housing is opened, so that half of the resonator is freely accessible. The

We investigate a differential sensor setup utilizing acoustic pressure waves, which aims at the determination of the acoustic viscosity (or the second coefficient of viscosity) of highly viscous liquids with shear viscosities in the range of several

We present a viscosity and density measurement principle based on diamagnetically stabilized levitation of a test object (a floating magnet) in the fluid to be characterized. Miniaturized resonant viscosity sensors are usually operated at relatively
