The two degrees-of-freedom device works based on mechanical vibration principles. When TRID comes into contact with a soft tissue, it identifies the tissue's viscoelastic properties through the change of its natural frequencies and damping ratios. By working in the linear viscoelastic domain, TRID is designed to identify tissue properties in the range of 0-100 Hz. Assuming Kelvin tissue model, a method is developed for determining unknown tissue parameters using input-output data from TRID. A parametric identification method using the prediction error approach is proposed for identifying the unknown tissue parameters, which is proved to be globally identifiable, in a grey-box state-space model. The effectiveness of the identification method is demonstrated using simulation in the presence of considerable input and output noises.","PeriodicalId":375470,"journal":{"name":"International Journal of Biomechatronics and Biomedical Robotics","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124441541","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}

IPMC sensors offer several advantages over conventional sensors; such as flexibility, conformability and durability are useful for impact sensing. The aim of the paper is to demonstrate the ability of IPMC as an impact sensor to be used in sport science. The ability to measure impact force or energy is important in sport science as this information can be used to improve athletes' performances. In this research, experiments were conducted for different impact energies and a mathematical model based on the impact sensor's output voltage spike's slope was developed. Testing using this model demonstrated that the accuracy of the measured impact energy is mostly within ±10% although an error of up to 25% was observed at low impact energies.","PeriodicalId":375470,"journal":{"name":"International Journal of Biomechatronics and Biomedical Robotics","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126294209","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}

Control strategy was evolved by mapping surface EMG (SEMG) from four muscles of healthy lower limb of a unilateral trans-femoral amputee and knee flexion angles (KFA) during various phases of a gait cycle. The SEMG and KFA are calibrated to three walking speeds modes i.e., slow, normal and fast. Sensor mechanisms feeds real-time data to controller to generate an appropriate control output signal based on available knowledgebase which calculates the patient's gait parameters i.e., KFA and SEMG from associated muscles during the corresponding phase of walk. Important aspect of control strategy is the development of knowledgebase proves that the SEMG signal generates recognisable pattern for change in walking speed when signals were analysed in time and frequency domain. These patterns were quantified and utilised for controlling electro-pneumatic knee joint.","PeriodicalId":375470,"journal":{"name":"International Journal of Biomechatronics and Biomedical Robotics","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131679508","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}

A rapid automated biodosimetric system used to assess thousands of individual radiation exposure doses is helpful to curb mass panic, and to conserve limited medical resources. This paper presents the development of a new robotically-based automated biodosimetry tool (RABiT). The RABiT is capable of automating two mature biodosimetry assays: the micronucleus and γ-H2AX assay. The design considerations guiding the hardware and software architecture are presented with focus on ease of implementation, methods of communication and need for real-time control versus soft time control cycles. Advanced technological developments for the RABiT including multipurpose gripper, non-contact laser cutting, automated biology protocols and transferring of the samples to a transparent substrate and high-speed multiple camera imaging are described in detail. The evaluation results show that the RABiT prototype has a throughput of 5,859 samples in an 18-hour duty cycle.","PeriodicalId":375470,"journal":{"name":"International Journal of Biomechatronics and Biomedical Robotics","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123815045","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}

The biostretch apparatus employs non-contact electromagnetic force to uniaxial stretch an engineered-tissue construct. A reliable controller is implemented to independently control four stretch parameters: strength, frequency, pattern and duration of the stretch time. The non-contact driving force and the specially designed mounting tray allow researchers to use standard Petri dishes and commercially available CO2 incubators to culture the tissue construct with mechanical stimulus. The apparatus greatly simplifies the culture process over existing biostretch apparatuses. Further, unlike traditional uniaxial stretch apparatuses, which normally fix one side and stretch other side, the new biostretch apparatus can also apply uniaxial stretch from both ends simultaneously. Using the biostretch apparatus, the distribution of strain on the Gelfoam® and GE RTV 6166 silicon scaffold is quantitatively analysed. With this apparatus, the effects on cell proliferation and orientation are also investigated.","PeriodicalId":375470,"journal":{"name":"International Journal of Biomechatronics and Biomedical Robotics","volume":"234 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134599274","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}

Second, human subjects were recruited to perform planar arm reaching task in different directions. Kinematic data collected by a motion capture system was used as the input to the simulation model.

Clubfoot is a historical foot deformity where foot turned in and pointed down causing the subject to walk on the outside edges of foot. The non-surgical correction of this deformity is an unsolved challenging problem in medical domain. An AFO is a device for correction of foot deformities such as clubfoot in this case. A mechanism is proposed that when fitted to AFO, control the motion of the abnormal foot during correction. The linkage is attached to the foot and shank of the AFO. As the fly nut is rotated the downward force will be transmitted to the forefoot region to dorsiflex the clubfoot and correct this deformity. The magnitude of the force can be controlled by number of rotation of the fly nut. The initial wearable prototype has been proposed and is ready for fabrication and testing on test subjects to demonstrate the feasibility of the concept.","PeriodicalId":375470,"journal":{"name":"International Journal of Biomechatronics and Biomedical Robotics","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127062275","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, a simple model of the sensor's response to rotary joint motion is proposed, based on experimental findings. The testing apparatus used in this study was designed and built to closely relate to the geometries and movement of a human finger joint.
