Opis:
Trunk orthosis affects trunk by a corrective-pressure mode with an objective to correct deformities (e.g. scoliosis). The effectiveness of this function depends on various factors, i.e. correct orthosis manufacture, correct application to patients and regular pressure corrective effect control. All these factors can be monitored by a system for measurement and evaluation of the contact pressure between the instrument and trunk in a real time and also by a so called “off line” system data recording. Presented article describes the application of made-to-measure sensor system TACTILUS (Sensor Products, USA) in different regimes (ambulance – A, home – H, combined – HA and multi-sensory ambulance – MA regime), testing of chosen static and dynamic matrix tactile sensor (MTS) parameters and results of the testing application between orthosis and patients' trunks.

Opis:
Thermal analysis of laser processes can be used to predict thermal stresses and consequently deformation in a completed part. Analysis of temperature is also the basic for feedback of laser processing parameters in manufacturing. The quality of laser sintered parts greatly depends on proper selection of the input processing parameters, material properties and support creation. In order to relatively big heat stress in the built part during sintering process, the thermal simulation and thermal analysis, which could help better understand and solve the issue of parts deformations is very important. Main aim of presented work is to prepare input parameters for thermal simulations by the use of RadTherm software (Thermoanalytics Inc., USA), directly during the sintering process and after the process and find out the impact of the heat stress on a final shape and size of the prototype. Subsequently, an annealing process of constructed products after DMLS could be simulated and specified.

Opis:
Some of the frequent reasons of titanium implant failures in human body are incorrect biomechanical interactions within the tissue-implant interface and inflammatory processes arising around the implant's application area. For both processes, it is crucial to locate them and intervene in time. One of the monitoring possibilities of the mentioned processes is the application of amorphous glass-coated sensoric microwires (AGCSM). Magnetic characteristics of these microwires are influenced by both mechanical tension (magnetoelastic interaction of the magnetic moment with mechanical stress) and by temperature (different coefficient of thermal expansion of the metal core and glass coating). The key task, in order to change the magnetic characteristics of AGCSM from both clinical and scanning point of view, appears to be the fixation pattern of AGCSM in the implant's body. The presented study shows the impact of four types of AGCSM fixation patterns (at one ending, at both endings, in the middle and along the entire length) on the thermal response process tested in laboratory conditions. The obtained results will enable to establish the AGCSM fixation methodology in the implant's body in order to achieve optimal output temperature parameters form the implant and the tissue-implant interface by magnetic contactless measurements.

Opis:
Few examples of technical and biomedical applications of bistable magnetic microwires are shown. Particularly, application of microwires in civil engineering are shown for sensing the mechanical stress in concrete, steel structure or steel cable by simple gluing it on the surface of studied structure. On the other hand, biomedical applications for sensing the stress, temperature, and position inside the human or animal body are shown. Experiments with pig intestine cells points to the biocompatibility of glass coated microwires.
