This project aims to overcome this limitation by building an interface to allow the user to control the trajectory of the robotic feet in real time. The interface consists of index and middle fingers simulating foot movements that are translated into movements of the feet of the biped robots in the sagittal plane. The finger movements represent the ankle trajectories and are converted to angular trajectories of robotic feet with 2-degrees of freedom using an inverse kinematics model.","PeriodicalId":153112,"journal":{"name":"2013 39th Annual Northeast Bioengineering Conference","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122925936","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}

Using a C coding software program, an algorithm is established to first detect an electromyographic signal and then to determine the strength of contraction of the muscle. A PIC microprocessor and printed circuit board (PCB) are also used to implement this task. Specifically, the amplitude of each contraction is studied to determine a weak, medium, or strong contraction type. This system can be used towards making objects (such as a wheelchair) move with different accelerations based on the strength of contraction of some muscle on the body.","PeriodicalId":153112,"journal":{"name":"2013 39th Annual Northeast Bioengineering Conference","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122027108","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}

Commercially available wound dressings do not allow for the control of moisture during the healing process. In this design, we introduced a gradient in cross-linking density, with increasing swelling tendency further from the wound surface, so that wound exudate can be wicked away in a controlled manner. This design is expected to prevent both overhydration (maceration) and drying of the wound surface. In addition, the antibacterial potential of the dressings was improved through the addition of silver and copper ions. Release of these metal ions from these hydrogels was controlled through hydrogel crosslinking density. The combination of silver (Ag+) and copper (Cu2+) is expected to inhibit the growth of a broader range of bacteria at a lower cost than silver alone.","PeriodicalId":153112,"journal":{"name":"2013 39th Annual Northeast Bioengineering Conference","volume":"289 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116589176","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}

Finite element models were constructed in mandible having single screw-type implant fixture connected to the premolar superstructure; this was done in order to evaluate how the length, diameter, and platform shape of a screw-type fixture influence the stress in the supporting tissue around fixtures.","PeriodicalId":153112,"journal":{"name":"2013 39th Annual Northeast Bioengineering Conference","volume":"51 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114024396","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}

Digital signal processing algorithms including digital filer, peak identification was developed to decimate the signal noise and compute the period. The heart rate (HR), heart rate variability (HRV), breath frequency can be determined. The performance is compared with conventional ECG system in clinic study. It shows high potential to collect effective information for clinic application.","PeriodicalId":153112,"journal":{"name":"2013 39th Annual Northeast Bioengineering Conference","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126211606","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}

Existing technologies are limited in that they typically feature protein micropatterns that are static and unable to change while cells are attached. Here we micropatterned shape memory polymer (SMP) substrates that were capable of transitioning from a stretched state to a contracted state to control the width of patterned lines presented to attached cells. We found that micropattern geometry changed as the SMP substrate transitioned to its unstretched shape. Cells attached to dynamic patterns balled up and contracted their nuclei. The results suggest that micropatterned SMP cell culture substrates can be used to study the temporal aspects of cell mechanobiology.","PeriodicalId":153112,"journal":{"name":"2013 39th Annual Northeast Bioengineering Conference","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130200235","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}

Prematurity is a significant problem in developing countries, where preterm infants make up approximately 25% of all live births. The World Health Organization (WHO) and Engineering World Health (EWH) have both expressed the necessity for a low cost, transportable infant incubation unit that can be used specifically for transit. The incubation unit is a TCNJ legacy project; several improvements were proposed to an existing design. The HVAC system was redesigned and will house the humidity and heating systems. A new humidity system has been added with both measurement and control. A new heating element has been designed using heating coils typically found in household appliances. A test baby model was designed using information about the size and thermal characteristics of a preterm infant so that the safety and efficacy of the design can be assessed. SIMULINK modeling of the incubator and a model of a baby will be used to better understand the thermodynamics of the system during operation. Manufacture, assembly, and testing of this new design will be completed during Spring 2013.","PeriodicalId":153112,"journal":{"name":"2013 39th Annual Northeast Bioengineering Conference","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116316712","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}
