UPX 8400-1 (Sika AG, Switzerland) is used for the sample substrates. Sample production consists of a 3D print master model, silicone molding, PU casting, and finally electroless plating. The test sample design for Shore hardness measurement is based on ISO 7619-1:2010. ![]() In this study, we assess the hardness of PU material before and after Ag/AgCl plating. Silver/silver chloride (Ag/AgCl) electroless plating provides a conductive, electrochemically stable coating but the process may alter the mechanical properties of the electrode substrate. A biocompatible polyurethane (PU) can be produced in low hardness resulting in a soft and flexible electrode substrate. Thus, soft electrodes are crucial for eventual repetitive and long-term use like in neonatal intensive care units. Since infant skin is more sensitive than adult skin, soft electrodes are required to reduce the mechanical stress for this sensitive skin. The patient tries to reduce the errors and in doing so comes closer and closer to the ideal movement of the therapist which guarantees the best possible therapy success.ĭry electrodes enable a shorter preparation time for infant EEG. By adjusting the bone lengths and angles in the individual frames of the patient's movement the selected sequence can be compared and any movement deviations that occur can be projected in directly in real time onto the patient's 3D avatar as an error image. Due to anatomical body differences, the reference skeleton must be adapted to the current patient skeleton, otherwise no movement evaluation can take place. The assistance system records the patient's movement in real time, extracts the its skeleton and compares this movement with the reference. Under this assumption a movement sequence of the therapist is recorded and a movement reference frame is extracted with the help of a smart sensor, which is made available to the patient as a target movement. This would be possible by transferring the therapist's movement into a patient's movement. To implement the therapeutic measures in a targeted manner, it is advantageous to transfer their knowledge to the patients. The aim of this paper is to provide an assistance system that can evaluate both the quantity and the quality of the movement performed using a goal-oriented model which gives the patient direct recommendations for action through automated, machine-monitored feedback. Currently, a therapist has to treat up to 15 patients at the same time on an outpatient basis. In Medical Training Therapy (MTT) the exact execution of training exercises developed by the therapist is crucial for the success of the therapy. ![]()
