Ultrasonic Array Transducer Using Interdigital Electrode

Japanese Journal of Applied Physics, 1984
A `planar array transducer' with interdigital electrodes is proposed. This paper describes the structure of the transducer and experimentally investigates its behavior and realization feasibility. A transducer directivity using PbTiO3 ceramics with a large electromechanical anisotropy shows the independent behavior of an array element that consists ...

Piezoelectric Fiber Composites with Interdigitated Electrodes

Journal of Intelligent Material Systems and Structures, 1997
Piezoelectric Fiber Composites were previously introduced as an alternative to monolithic piezoceramic wafers for structural actuation applications. This manuscript was an investigation into the improvement of piezoelectric fiber composite performance through a nonconventional electroding scheme.

Characterization of Interdigital Electrode Sensors

Surface Engineering and Applied Electrochemistry, 2019
The paper aims to determine the influence of the chosen geometrical parameters of an interdigital sensor and of the measuring cell on the sensor performance, with the final goal of optimizing those parameters. The cell here is a capacitive cell or resistive cell for titration without a particular type.

Single-crystal relaxor ferroelectric piezoactuators with interdigitated electrodes

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2004
We report on the fabrication and performance of (1-x) Pb(Zn(1/3)Nb(2/3))O3-xPbTiO3 (PZN-PT) single-crystal relaxor piezoactuators with interdigitated electrodes patterned on a single surface. An electric field gradient across the sample thickness induces a differential contraction between opposite faces, and it is responsible for the actuation.

Fluid streaming above interdigitated electrodes in dielectrophoresis experiments

ELECTROPHORESIS, 2011
AbstractFor the investigation of alternating current electrokinetic effects, a system is presented that allows for the simultaneous observation of fluid flow above and around microelectrodes in all three directions in space. Beside the usual microscopical view from top, lateral observation through the same objective is made possible by two small ...

Electrothermal pumping with interdigitated electrodes and resistive heaters

ELECTROPHORESIS, 2015
Interdigitated electrodes are used in electrokinetic lab‐on‐a‐chip devices for dielectrophoretic trapping and characterization of suspended particles, as well as the production of field‐induced fluid flow via AC electroosomosis and electrothermal mechanisms.

Transparent Quasi-Interdigitated Electrodes for Semitransparent Perovskite Back-Contact Solar Cells

ACS Applied Energy Materials, 2018
Transparent quasi-interdigitated electrodes (t-QIDEs) were produced by replacing the opaque components of existing QIDEs with indium tin oxide (ITO). We demonstrate their application in the first semitransparent back-contact perovskite solar cell.

Electrode Resistance Effects in Interdigital Transducers

IEEE Transactions on Microwave Theory and Techniques, 1974
A distributed RC circuit model is used to describe an interdigital electrode transducer (IDT) having finite conduction in the electrode stripes. The distributed circuit is described by a set of differential equations whose solutions yield the current and voltage distributions along the aperture of the IDT.

Microbead-based electrochemical immunoassay with interdigitated array electrodes

Analytical Biochemistry, 2004
The objective of this study was to develop a sensitive and miniaturized immunoassay by coupling a microbead-based immunoassay with an interdigitated array (IDA) electrode. An IDA electrode amplifies the signal by recycling an electrochemically redox-reversible molecule.

Nanoscaled interdigitated titanium electrodes for impedimetric biosensing

Sensors and Actuators B: Chemical, 2000
Nanoscaled interdigitated electrodes (IDEs) are developed for the purpose of being used as miniature and sensitive affinity biosensors. Because of the ease to derivatise its surface, oxidized Ti is chosen as an electrode material on a SiO2 substrate. For proof of principle, oxidized and non-oxidized Ti IDEs are characterised in salt solutions and the ...
