Foot plantar pressure is measured using a shoe insole with 8 sensors placed in different anatomical zones of the foot, and placed inside a sports footwear. Polarized PVDF foil is used as a sensor material. A wireless transmission system is used to transmit voltage values to the computer. Due to linear relationship between force and transducer voltage, energy released during walking in arbitrary units can be calculated as integral of the square of transducer voltage over time. Gait measurements have been done over the next few days on healthy person during normal walking and slow walking. Performed measurements allow determination of walking speed (number of steps per second), gait rhythm and manner of walking (applying force to inside versus outside part of the sole). It is found that switching from normal to slow walk increases gait energy by 25% while the pressure distribution across the anatomical regions of the foot remains unchanged. The results will be used for developing a programme for evaluation of patients with cardiac failure and future integration of actimetry with pulse and spirometry measurements.","PeriodicalId":101814,"journal":{"name":"Scientific Conference on Optical and Electronic Sensors","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133080514","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}

Presented sensor was fully fabricated with the inkjet printing technology on thin Kapton substrate. The measurement of liquids level based on capacitive sensing is already well known technique, however the novelty of presented sensor is the technology of fabrication that was used, approach to the pattern design which combines analog and digital capacitive section and obtained self-calibration feature of whole system independently on measured liquid type. Fabricated sensor structure has dimension of 210 mm x 12 mm and the thickness approximately of 27 μm. It contains 8 digital-like sections along the sensor and one analog section which allows to fine measurements. The sensor was tested in a vessel during filling and emptying with various liquids. Performed tests exhibited the linearity of the sensor characteristic and the lack of hysteresis. Obtained sensitivity of the sensor prototype was approximately 6.8 pF/mm, but it could be easily modify on the design stage due to the fast prototyping feature of inkjet printing technology. Thanks to the flexibility of the substrate, the sensor structure can be applied to any shape of vessel. Furthermore, the sensor construction is fairly simple and costs in mass production could be extremely low. This type of sensor was design especially for autonomous cleaning and washing robots for large areas operation.","PeriodicalId":101814,"journal":{"name":"Scientific Conference on Optical and Electronic Sensors","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122993446","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}

These chemical particles are present during technological steps required for a device fabrication and may lead to significant changes of graphene properties. The investigation has been done by means of ab-initio simulation based on the DFT method. A MedeA-VASP package was used to investigate behavior of graphene layer in the vicinity of chemical compounds. Presented studies show that properties of graphene are significantly modified when particles of H2O and NaOH are captured in-between graphene layer and SiO2. Special attention should be paid to NaOH which, according to simulations, decays and modifies the properties of graphene layer.","PeriodicalId":101814,"journal":{"name":"Scientific Conference on Optical and Electronic Sensors","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123011722","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}

Proximity sensors based on optical fiber are highly required especially in the impact area of electromagnetic fields. In this paper three different types of fiber optic reflective sensors are presented. In all three types of the sensor four multimode optical fibers (MMF) illuminate the movable surface. The difference is in the number of collecting the reflected light MMF. In the first one, 12 MMF collect the light, in the second one 20 MMF, while in the third one the number of MMF collecting reflected light is 32. Moreover, all three types of fiber optic reflective sensors were realized in two configurations. In the first one, the cleaved MMF were used to collect reflected light, while in the second configuration – the ball-lensed optical fibers were chosen. In this paper an analysis of each type of realized sensor is presented. In the last part of this paper the obtained results and the detailed discussion are given.","PeriodicalId":101814,"journal":{"name":"Scientific Conference on Optical and Electronic Sensors","volume":"10161 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129373651","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 the approach of using a single sensor and special measurement techniques will be presented. Instead of increasing the number of sensors an additional information, needed to improve the properties of the sensor, is obtained from the response signal of a single sensor.","PeriodicalId":101814,"journal":{"name":"Scientific Conference on Optical and Electronic Sensors","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115368647","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}

After electrophoresis, the gels are commonly stained for protein band analysis with silver stain; this allows the detection of protein loads to about 1 ng. To increase the detection sensitivity of the protein bands down in the subnanogram level, a sensor has been developed based on the thermal lens effect to scan and quantify protein loads which would remain undetected using the standard imaging systems. The thermal lens sensor is equipped with a 450 nm diode pump laser modulated at 1 Hz and a HeNe probe laser mounted in collinear geometry. The sensor could detect protein bands of 0.05 ng when the gel was soaked in methanol/water and 0.1 ng in water. The limit of detection ranged from 8 to 20 pg, depending on the soaking medium and the staining efficiency. Thus, the detection of silver stain by thermal lens effect results 10 to 20 times more sensitive than the standard colorimetric method.","PeriodicalId":101814,"journal":{"name":"Scientific Conference on Optical and Electronic Sensors","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127249407","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}
