The training required to learn how to use an exoskeleton for assisted walking is currently based on a subjective evaluation of gait by the patient and his therapist, with a trial and error approach that increases the time and effort required to reach an efficient walking rate. To provide therapists information on the training progress, as well as on upper limb involvement in assisted gait, a measurement system was developed, by instrumenting Lofstrand crutches and integrating them with the sensing framework commonly found in gait analysis laboratories. Each crutch is composed of three strain-gauge bridges for measuring axial and shear forces, a conditioning circuit with transmission modules, a tri-axial accelerometer, and a power management circuit with two batteries. Data are transmitted wirelessly via Bluetooth to a personal computer, avoiding any interference with the user's gait. To estimate upper limbs' internal forces, an inverse dynamics analysis of the measurement results was performed on a biomechanical model developed by the authors. Internal forces acting on shoulders, elbow and neck were computed, to assess loads on the joints, as well as torques acting on the system degrees of freedom, due to the muscular activity of the subject. The presented approach was applied to Rewalk© users at different stages of their training, and with different walking performances. The paper presents the description of the measurement system, as well as an example of the results of these case studies, showing how this solution could be used to quantify important parameters to guide the user training during assisted gait.","PeriodicalId":395550,"journal":{"name":"2015 6th International Workshop on Advances in Sensors and Interfaces (IWASI)","volume":"35 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121011624","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 particular, the two cases of hyperbolic and linear capacitive behavior have been considered. The capacitive evaluation can be done by the design and characterization of a suitable electronic circuit which determines the measurand variations through the reading of a voltage. This approach has shown high accuracy as well as other solutions reported in the literature where the capacitances are typically converted into a frequency. The front-end has been designed in a standard CMOS technology (AMS 0.35 um) to work at dual supply voltages (1.65 V each), so to be suitable for low-cost portable applications. Spice simulations on the designed integrated solution and experimental results using a discrete-component prototype have shown a reduced absolute percentage error (lower than 1% and 3.5 %, respectively), if compared to theoretical expressions. Sensitivity and resolution on a practical case study of the sensor/interface system are also given, showing very satisfactory values.","PeriodicalId":395550,"journal":{"name":"2015 6th International Workshop on Advances in Sensors and Interfaces (IWASI)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127049047","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 platform consists of a passive UHF RFID tag and a base station. The tag has an inductively-fed, meandered dipole antenna that is impedance matched to a CMOS IC that contains the remote powering, power management, and communication circuits to operate with sensor interfaces. The power management includes an LDO voltage regulator, a bandgap voltage reference, and a current source. The rectifier is a three-stage, differential rectifier with threshold cancellation. The regulator is responsible for generating a stable supply voltage for sensor interfaces. The reference voltage of the voltage regulator is generated by the bandgap voltage reference. The supply independent current source generates a reference current to be used in the sensor interface circuit blocks. The tag chip has a backscattering modulator with a 1-bit data input to transmit the sensor interface output to the base station. A monostatic base station with a homodyne receiver is implemented using discrete components and a custom-made planar patch antenna. The operation of the whole system is shown by measurements. The tag chip is implemented in 0.18 μm UMC CMOS process.","PeriodicalId":395550,"journal":{"name":"2015 6th International Workshop on Advances in Sensors and Interfaces (IWASI)","volume":"72 5 Pt 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132470327","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}

Wireless body area networks (WBAN) technology has gained popularity over the last few years, with a wide range of applications covered, in particular in health and rehabilitation. Wearable and pervasive computing are able to sense, monitor and process the data to provide smart assistance and context-aware ambient intelligence environments. However present-day WBAN devices are mainly battery-powered and due to energy issue they need to be recharged every day or even hours and thus they miss the expectations for a truly unobtrusive user experience. This work presents a novel energy-efficient asynchronous MAC protocol using a nano-watt wake up radio with addressing capabilities to reduce the energy consumption of the communication and then extend the WBAN life time. We present the benefits of the wake up radio in a star topology widely used in WBAN where the number of the node is around 5 to 10. The implemented protocol exploiting the low power consumption of the wake up radio, the low latency and the addressing capabilities can increase significantly the energy efficiency of the single node and entire network reducing both idle listening and data collisions. Result based on measured power consumption and OMNET++ simulation demonstrate that by using the wake up radio it is possible to reduce the power consumption up to 150 times compared to related protocols and the lifetime can be significantly increased in a real world scenario.","PeriodicalId":395550,"journal":{"name":"2015 6th International Workshop on Advances in Sensors and Interfaces (IWASI)","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127393724","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}

Furthermore intelligent mobile medical devices are on the brink of introducing safe and highly sophisticated systems to help a broad patient community to regain a considerable amount of life quality. The major challenges which are inherent in such integrated system's design are mainly to be found in obtaining a compact system with a long mobile autonomy, capable of delivering the required signal requirements for EMG based prosthetic control with up to 32 simultaneous acquisition channels and - with an eye on a possible future exploitation as a medical device - a proper perspective on a low priced system. Therefore, according to these requirements we present a wireless, mobile platform for acquisition and communication of sEMG signals embedded into a complete mobile control system structure. This environment further includes a portable device such as a laptop providing the necessary computational power for the control and a commercially available robotic hand-prosthesis. Means of communication among those devices are based on the Bluetooth standard. We show, that the developed low cost mobile device can be used for proper prosthesis control and that the device can rely on a continuous operation for the usual daily life usage of a patient.","PeriodicalId":395550,"journal":{"name":"2015 6th International Workshop on Advances in Sensors and Interfaces (IWASI)","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121999335","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}
