Magnetic‐Driven Torque‐Induced Electrical Stimulation for Millisecond‐Scale Wireless Neuromodulation
Advanced Healthcare Materials, EarlyView.MagTIES is a wireless neuromodulation technique with millisecond precision. It employs magnetic‐driven torque from magnetite nanodiscs to activate piezoelectric nanoparticles, enabling precise temporal control of neuronal activity and brain oscillations using weak, low‐frequency magnetic fields.

Our objects of study are infinite sequences and how they can be transformed into each other. As transformational devices, we focus here on Turing Machines, sequential finite state transducers and Mealy Machines. For each of these choices, the resulting transducibility relation ≥ is a preorder on the set of infinite sequences.

Opposite Phased Transducer — Novel Type of Transducer
AIP Conference Proceedings, 2004Defect sizing is an important task giving input to fracture mechanics evaluation. The exact evaluation of sound field is the key factor to analyse precisely defects in materials. Sizing accuracy is affected by the size of the sound field. There are several methods available for sizing: SAFT, Acoustic Holography, Tip diffraction, Amplitude drop. In SAFT

An Electromechanical Transducer
Transactions of the American Institute of Electrical Engineers, 1951As the telemetering art progresses under the impetus of both aircraft and industrial needs, the requirement for accurate transducing becomes more and more important. This article describes a null-balance type of transducer which is inherently capable of achieving an accuracy comparable to that of present-day transmission links.

Proceedings of IEEE Ultrasonics Symposium ULTSYM-94, 1994
Reverberations from reflections at the transducer surface are overlaid on first order echoes from deeper targets and sometimes obscure these heavily. A method to reduce this artifact consists of acquiring two scan lines in the same direction with the transducer displaced slightly.

From IPMC Transducers to All-Organic Transducers
2013This paper presents a summary about the research activity performed on characterizations and modeling of new polymeric transducers. More specifically, Ionic Polymer–Metal Composites (IPMCs) have been widely explored and a new class of totally organic transducers: Ionic Polymer-Polymer Composites (IP2Cs) have been introduced. The manufacturing technique,

Contacting Transducers and Transducer Arrays for NDE
1981 Ultrasonics Symposium, 1981We have designed and built a longitudinal wave and several shear wave contacting a rrays for the nondestructive evaluation of aluminum. The arrays each have 32 elements and operate at a center frequency of 3 MHz . Side drilled holes and EUM slots of different orientations (all of which are in aluminum sample blocks) a re imaged using these arrays in a ...

Review of Scientific Instruments, 1948
A description is given of a transducer which utilizes, for the transformation of sonic to electrical energy, the electrokinetic potential developed by the movement of a fluid through a porous solid. The construction and calibration of the transducer are discussed, and results of measurements of the pressure fluctuations in oil pipe lines are presented.

The transducer is the indispensable part of any medical ultrasound system. Transducer design is based on an accurate transducer simulation model such as the electroacoustic KLM transducer equivalent circuit model which is explained in detail and in Appendix C. A useful design perspective is that a transducer and/or model has a three ports: two acoustic

Transducers III—Other Transducers
1996Crystals have always had a fascination for people. Are not diamonds a girl’s best friend? Their perfect shapes, their colours and the way they can be grown from a clear solution have long had a fascination. They have been (and are) involved in magic and sorcery and ‘new age’ religion. But they also have considerable scientific importance.
