The foot is an anatomical structure of extreme importance in our body. Through the joint interaction of numerous playersit allows the performance of foot and leg movementsenabling the execution of the orthostatic positiongait and run. The foot is under development in childrenundergoing changes in structure and shape. In this stage of foot developmentand due to the influence of numerous factorspathologies and/or injuries can occur. It is increasingly important that the diagnosis of postural changes and abnormal plantar pressure distributions be made between childhood and adolescenceso that it can be correctedoften through plantar orthoticsand prevention of more serious injuries. Natural polymers have been the subject of much research to obtain new sustainable materials. Nanocellulosea very abundant material on our planethas been the subject of research in the development of biomedical materials and nanocomposites reinforcement. Thusas the nanocellulose is a natural polymer with promising mechanical and biological propertiesthe possibility of its application to a foot orthotic was investigatedand this is the main purpose of this studypharmaceuticalthe methodologies used to obtain the nanocellulose gel are presented and analyzedas well as the characterization of the same gel using several techniquessuch as resistance to compression and density evaluation. Based on the evaluation of the obtained resultsit is intended to design a prototype of foot orthoticto correct the distribution of plantar pressuresand to test the same in the study population with alterations of plantar pressurewith alterations of other possible applications of this unique material.

Entwicklung und Charakterisierung von flexiblen Verkapselungsschichten für elektrisch aktive Implantate AuthorMichael Weinmann Year2017 SourceDissertation zur Erlangung des Doktorgrades LanguageGerman Pages1-209 LUMiFracLFrac1478Implantatmedizin kommen vermehrt elektrisch aktive Mikroimplantate zur Überwa-chung und Stimulation von Körperfunktionen zum Einsatz. Als Beispiele sind Retina-Implantate zur Stimulation degenerierter Netzhäute und Hirnimplantate zur Überwachung und elektrischer Modulation von Hirnfunktionen bei Epilepsiepatienten zu nennen. Diese Mikroimplantate können im Gegensatz zu den konventionellen Implantaten (wie z.B. Herz-schrittmacher 18 more Chochlea-Implantate) nicht mit voluminösen und starren Titan- oder Keramik-gehäusen verkapselt werdendie verhinderndass die elektronischen Bauteile im menschli-chen Körper korrodieren. Es werden dünne Verkapselungsschichten benötigtdie eine mecha-nisch flexible Auslegung des Implantats ermöglichen und gleichzeitig eine diffusionsdichte Barriere gegenüber dem korrosiven Körperelektrolyten darstellen. In der vorliegenden Arbeit wurden mechanisch flexible Dünnschichtverkapselungen für elektrisch aktive Mikroimplantate entwickelt und charakterisiert. Die Verkapselungsschichten bestehen aus biokompatiblen Polyimid-Parylen-C-Polymerverbundendie mit dünnen Titan-Gold-Titan-Wasserdampfbarrieren beschichtet sind. Das Ziel dieser Arbeit bestand darindie Verkapselungsschichten hinsichtlich ihrer Biostabilität zu untersuchen und den dominierenden Permeationsmechanismus durch die Verkapselungsschichten zu identifizierenumdarauf aufbauendHerstellungsvorschriften abzuleitendie die Herstellung von hochdichten Barrie-ren gestatten. Die Haftfestigkeit zwischen den einzelnen Funktionsschichten wurde mit der Gitterschnitt-prüfmethode und einer ZentrifugenprüfmethodeElectrically active micro-implants are increasingly used in the medical device industry to monitor and stimulate body functions. Examples are retina implants for stimulation of dege-nerate retinas and brain implants to monitor and stimulate brain functions for epilepsy pati-ents. In contrast to conventional implants like pacemaker or chochlear implantsmicro-implants can´t be encapsulated with bulky and rigid titanium or ceramic housings which pre-vent electronic components from corrosion in the human body. Thin encapsulation layers are requiredwhich enable a mechanically flexible design and represent a diffusion-tight barrier to the corrosive body electrolyte. This thesis describes how flexible encapsulation layers for electrically active micro-implants were developed and characterized. These flexible encapsulation layers consist of biocompa-tible polyimide-parylene-C-composites which are coated with thin titanium-gold-titanium water vapor barriers. The aim of this thesis was to investigate the encapsulation layers with respect to their biostability and to identify the dominant permeation mechanism through encapsulation layersso that design rules can be derived which allow the production of high density barriers. The adhesion strength between the individual functional layers was investigated by using cross cutting and centrifugal forces driven testsHaftfestigkeitsuntersuchung mit ZentrifugenprüfmethodeZur quantitativen Bestimmung der Haftfestigkeit der Metallbarriereschichten auf den Parylen-C-Schichten wurden ZugabzugsversucheAdhäsions-Kohäsions- oder Mischbruch vorlag.
