N2 - In the article on hand, two types of a non-actuated assistive device which should assist persons suffering tremor disease are presented. The device should help patients in the everyday life situation of drinking and replace devices currently used, such as feeding cups. The device's function is based on a mechatronic cup holder system published recently. Both concepts of the fluidic cup holder device comprehend two concentric cups, of which the inner one contains the beverage and the outer one a damping fluid. Looking at the first concept, the inner cup is fixed to the outer one by use of a wire at its bottom. With the second concept, the inner cup is affixed using a membrane. For both concepts, the beverages' motion provoked by the patient's tremor is balanced by the inner cups' motion and damped by means of the damping fluid. The main benefit of the new device is its fully passive configuration. It does not need any power to realize its function. Besides the description of the two assistive devices' function, the second cup holder concept is modeled mathematically. The significant parameters have been determined. Experiments have been conducted to analyse the influence of the damping fluid's viscosity. In future, the test set-up can be used to test other parameters' influence or other concept models. Furthermore, tests with patients can be carried out to determine the devices' benefit and acceptability.
