Since the HDMEA enables to record the activity of single neurons at sub-cellular resolution, a combination with intracellular recording techniques, such as patch clamp, will allow for new in vitro experiments. Such combination technique requires precise localization of both the cell of interest and the glass micropipette (GM) with respect to the HDMEA. Here, we present a methodology to locate the three-dimensional (3D) position of a GM on the HDMEA without the use of an optical microscope. For the (x, y) position, the achieved accuracy is (±2μm, ±5μm), which is less than the electrode pitch of 18μm. For the z-position, the obtained accuracy is ±2μm for distances of 5-50μm between the GM tip and the HDMEA surface. We also observed that variations in size of GM tips and HDMEA electrodes have minimal effects on the blind localization performance. This approach shows the feasibility of automated navigation of a GM atop the HDMEA to patch a single cell in vitro.","PeriodicalId":258260,"journal":{"name":"2013 IEEE SENSORS","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121400807","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 system was developed for improving inertial measurement unit (IMU) positioning accuracy. The HD-GRSA is composed of 26 × 26 sensing nodes, which can measure dynamic ground force and shear strain associated with a ground locomotion gait. Each electronic detection channel consists of a front-end multiplexer that can sequentially connect individual sensing nodes from a 13 × 13 sub-array to a capacitance-to-voltage (C/V) converter followed by a 12-bit algorithmic ADC. The electronics were fabricated in a 0.35 μm CMOS process occupying an area of 7.7 mm2 for each channel while dissipating a DC power of 3 mW from a 3V supply. The HD-GRSA demonstrates the designed functionality achieving a gait ground velocity resolution of approximately 95 μmRMS/sec, limited by the electronic interference signals due to the long metal traces on the sensor array. Further performance improvement is expected by employing interference suppression techniques and better matching for critical wiring traces.","PeriodicalId":258260,"journal":{"name":"2013 IEEE SENSORS","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125319409","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}
