Design, Product Development and Risk Assessment of Tin (sn) ring electrodes as a substitute to Silver-Silver Chloride (AG AgCI) ring electrodes for High Definition transcranial Direct Current Stimulation (HD-tDCS)
… thesis is to test the viability of Tin (Sn) ring electrodes as an inexpensive alternative to sintered Silver-Silver Chloride (Ag|AgCl) ring electrodes for High Definition – transcranial Direct Current Stimulation (HD-tDCS). Throughout our initial bench top testing of tin electrodes in …

Design and characterization of variable acoustic field amplitude and focusing ultrasonic transducers
Ultrasonic transducers with concentric annular ring electrodes can be used to generate various circularly symmetric acoustic field profiles. These transducers can also electronically simulate a circular phased array and generate a focused ultrasonic beam. A model which predicts the acoustic …

Design and modeling of a PZT thin film based piezoelectric micromachined ultrasonic transducer (PMUT)
… PMUT with an arbitrary number of circular or ring electrodes. The resulting solution is much simpler and more flexible than previously published solution techniques enabling the optimization of electrode configuration for large deflection and acoustic pressure. Additionally, the contribution …

Comparison of tripolar and traditional recording of the pattern-reversal visual evoked potential: signal and noise
… limited spatial resolution. Tripolar concentric ring electrodes (TCREs) provide an EEG measure (tripolar EEG; tEEG) designed to reduce these issues. Many studies using tEEG via TCRE systems have demonstrated successful noise reduction in recording muscle-related potentials and seizure detection. …

The micro-optical ring electrode: Development of a novel thin ring based device for spectrophotoelectrochemistry and its application to the study of rose bengal
… and devices such as rotating optical disc ring electrodes, optically transparent electrodes and optically transparent thin layer electrodes. A microelectrode is an electrode with at least one of its characteristic dimensions of less than 50 pm. This provides a number of advantages to such …

Nonthemal plasma synthesis of indium phosphide nanocrystals and electrical properties of doped silicon nanocrystal films.
… flowed through a 3/8” quartz tube with two outer ring electrodes. The size of the NCs was primarily controlled through the residence time of the NCs in the plasma. Residence times of 2-10 ms lead to particles with mean sizes between ~2.5-4 nm with size distributions less than 25% of the mean …
