This wearable assistive device is not environment-dependent such as a transferring lift or slide board. The assistive device sustains the caregiver's weight at his/her hip by landing a floor with a wheel during transferring assistance. This paper proposes a unique mechanism to change the landing point according to the task progress. The position of the landing point is mechanically controlled to follow center of gravity of the caregiver so that he/she could move right and left with less effort while he/she is unweighted. The mechanism also prevents a caregiver's falling backward while bracing the caregiver's hip part at arbitrary height. These functions are confirmed through experiments by measuring ground reaction forces and myoelectric potential of the caregiver.","PeriodicalId":181514,"journal":{"name":"2014 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124703894","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}

Conventional speaking valves have one-way valve mechanism, they open when the user breathes in, and they close when user breathes out and produces a voice. This type is very simple and tough, but it has a problem about closeness of the user. This problem is caused by its mechanism what can not be controlled by user's will. Therefore, we proposed a myoelectric control-type speaking valve. This valve can be controlled by the myoelectric signal of sternohyoid muscle. From our previous results, it was clarified that this valve had better performance about easy-to-breath. But, the previous valve was too big and heavy to carry. In this report, we describe the development of compact myoelectric control-type speaking valve system. The new-type speaking valve is enough small to attach the human body, and its opening is larger than that of conventional speaking valve. Furthermore, the shape of flow channel is optimized by FEM analysis. According to the result of this analysis, this valve gets the low flow resistance channel.","PeriodicalId":181514,"journal":{"name":"2014 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121463442","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}

Fabrication of a 2D dispenser array requires multi-layer architecture and through holes. PDMS through holes were formed via replication from a two-layer SU-8 mold. We measured transportation of particles through a via-hole. We fabricated top and bottom layer structures of 2D dispenser array. Attachment of a probe array to a microchip enables dispensing multiple droplets containing biomolecules from the probe array.

The robot consists of a stick, a group of sensors and an omni-directional basis driven by three Swedish wheels. Multiple sensors were used to recognize the user's “walking intention”, which is quantitatively described by a new concept called intentional direction (ITD). Based on the guidance of filtered ITD, a novel intention-based admittance motion control (IBAC) scheme was proposed for the cane robot. To detect the fall of user, a detection method based on Dubois possibility theory was proposed using the combined sensor information from force sensors, a laser ranger finder (LRF) and an on-shoe load sensor. The human fall model was represented in a two-dimensional space, where the relative position between the center of pressure (COP) and the center of support triangle was utilized as a significant feature. The effectiveness of proposed fall detection method was also confirmed by experiments.","PeriodicalId":181514,"journal":{"name":"2014 International Symposium on Micro-NanoMechatronics and Human Science (MHS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134578965","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 research, the light driven SMA actuator has been fabricated with an optical adhesive. The optical adhesive consists of organic materials, epoxy and acrylic. The adhesive has a high light permeability. Additionally, the adhesive can be easily deposited as thin film because it has paste form and is an ultraviolet curable adhesive.

The gliding assays serve as a basis of applications of motor proteins for nanotechnology. For example, cargo-loading cytoskeletal filaments propelled by the associated motor proteins, which is so-called molecular shuttles (MSs), can be alternative to conventional transport on Lab-on-a-Chip. During the developments, researchers have encountered biophysical phenomena which cannot be easily elucidated, such as detailed mechanisms of guiding of MSs by microfabricated guiding tracks. Elucidating such phenomena is important for the developments of microscale biomedical devices. However, elucidation of the phenomena has been hampered by lack of detailed information. Such information is difficult to obtain through experiments.

However, there are few study cases about the percolation process of the medicine at the time of a hypodermic injection, design of the needle in consideration of the efficiency of drug penetration as well as durability despite being sought, the design of the hypodermic needle for medication which a medicine is made to permeate efficiently is not yet made. Therefore, confirmation of subcutaneous infiltration process has become an issue.
