There is a broad variety of devices for stimulating the hearing either acoustically, mechanically or electrically. Their applications depend on the type, the severity and the location of a particular impairment. In order to get an optimal reconstruction, additionally to the medical aspects the dynamical behavior of the implant has to be regarded together with the individual situation of the patient simultaneously. Because of the broad variation of individuals and situations, the belonging parameters are time dependent and vary in a wide range, too. Thus, the design of a hearing device must be robust or insensitive against parameter variation and a sensitivity analysis with respect to parameters of the device, variation of anatomy and variation of insertion is needed. By means of mechanical simulation models enhanced by the behavior of the actuator and its control, the dynamical behavior of implants can be calculated and optimized. Such simulations helps to shorten series of experiments in the lab and in clinical practice and guidelines for the designer and for the surgeon can be derived.","PeriodicalId":357085,"journal":{"name":"International Conference on Biomedical Electronics and Devices","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127009594","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}

Recent results have however shown that the conventional approach to their design, which consists in continuous wireless streaming of the sensed data to a central data collector, is unsustainable in terms of network lifetime and autonomy. Furthermore, it was established that wireless data communication is responsible for most of the energy consumption. To address the energy inefficiency of conventional WBSNs, we advocate an advanced WBSN concept where sensor nodes exploit their available, yet limited processing and storage resources to deploy advanced embedded intelligence and processing, to reduce the amount of wireless data communication and consequently energy consumption. More specifically, this paper addresses the design and optimization of an automated real-time electrocardiogram (ECG) signal analysis and cardiovascular arrhythmia diagnosis application for a prototype sensor node called Wireless 25 EEG/ECG system. The satifactory accuracy of this on-line automated ECG-based analysis and diagnosis system is assessed and compared to the salient off-line automated ECG analysis algorithms. More importantly, our results show an energy consumption reduction of 80% to 100% with respect to conventional WBSNs, when our analysis and diagnosis algorithm is used to process the sensed ECG data to extract its relevant features, which are then wirelessly reported to the WBSN central data collector, after the node can automatically determine the potential cardiovascular pathology without human monitoring.","PeriodicalId":357085,"journal":{"name":"International Conference on Biomedical Electronics and Devices","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127166078","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}

This processes aims to modify morphologically and chemically the superficial structure of the polymeric materials (PET), forming new carboxyl, hydroxyl and other polar groups at the surface, in order to increase adhesion and hydrophilicity. The increase in the hydrophilicity of the fabric was evaluated by measuring the contact angle being the best results obtained for the Texazym PES (87.45o), much smaller than the non-treated fabric (122.95o); and by the wicking height, which revealed an important improvement in the hydrophilicity. The formation of carboxyl and hydroxyl groups was evaluated by a staining procedure with a cationic and reactive dye, respectively. It was also confirmed by the increasing in the polar component of the surface energy, determined by the Qwens-Wendt method. The higher surface energy and thus, the higher adhesion properties, were obtained for the esterase Texazym, using 0.12U during 90 minutes. The surface morphology of the non-enzymatic-treated and enzymatic-treated samples was analyzed by scanning electron microscopy (SEM) showing no degradation of fibers treated under the selected optimum conditions. In contrary, this method showed an important surface cleaning action by removing some undesirable polyester oligomers.","PeriodicalId":357085,"journal":{"name":"International Conference on Biomedical Electronics and Devices","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133395217","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}

Instead of using the common approach of conventional eye trackers based on continuous pupil–corneal reflection detection, a simple method based on photogrammetry is proposed. This method only measures the head movements, the gaze direction and the visual map can be calculated on the hypothesis that subjects’ gaze follows a known visual stimulus accurately. In order to validate this hypothesis, an experiment has been carried out to calculate the subject’s accuracy when tracking the stimulus. The gaze direction was measured both with conventional eye tracking and with the proposed technique and the measured gaze angles were compared. The results show that the subjects effectively follow the stimulus during the task and thus the main hypothesis of the proposed system is confirmed. Therefore, the analysis of head movement can supply an indirect estimation of the visual angles that is as accurate as the measures obtained with more complex devices.","PeriodicalId":357085,"journal":{"name":"International Conference on Biomedical Electronics and Devices","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131811963","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}
