These characteristics were optimized by applying high frequency plasma treatment, in order to increase their suitability for electronic purposes. Starting from the surface texture parameters, a deep analysis of the surface topographies at the interface with certain compounds was performed. The action of the plasma species generates a prevalent granular surface morphology, with higher roughness, improved bearing characteristics and minimal surface orientation. In addition, after the plasma treatment, a greater interaction between the AFM silicon tip and the polyimide film occurred, reflecting an increased surface adhesion. The obtained data reveal that the processed semi-alicyclic polyimide exhibits optimal features for microelectronic applications such as silicon/polyimide interfaces for flexible electronics.","PeriodicalId":271843,"journal":{"name":"2014 International Conference and Exposition on Electrical and Power Engineering (EPE)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122708266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper is presented a noninvasive low cost health care system for Neurological Disorders Screening and Rehabilitation that can be used by doctors and patients, and also for research purposes. The system can assist the doctors/medical experts in monitoring, screening and rehabilitation of patients with Parkinson's disease or other Neurological Disorders, leading to an early and efficient diagnosis.

By summing the signals produced at the level of each activated motor unit we achieve an electrical signal that can be recorded as electrical waves. In this study we aimed to identify a correlation between different types of muscular contractions and the muscle electrical activity. 23 healthy persons aged between 19 and 52 years participated to this study. By recording the electrical activity of the triceps brachialis muscle during its contraction it has been found that the strongest electrical activity of the muscle was produced during isometric contractions, followed by eccentric contraction, contraction with weight in the hand, contraction against gravity and contraction without gravity. In other words, as the muscle load is higher the muscle electrical activity is more intense.","PeriodicalId":271843,"journal":{"name":"2014 International Conference and Exposition on Electrical and Power Engineering (EPE)","volume":"131 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115133462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
