This paper presents the magnetic resonator piano, an augmented instrument enhancing the capabilities of the acoustic grand piano. Electromagnetic actuators induce the strings to vibration, allowing each note to be continuously controlled in amplitude, frequency, and timbre without external loudspeakers. Feedback from a single pickup on the piano soundboard allows the actuator waveforms to remai...

Magnetically actuated ciliary microrobots were designed, fabricated, and manipulated to mimic cilia-based microorganisms such as paramecia. Full three-dimensional (3D) microrobot structures were fabricated using 3D laser lithography to form a polymer base structure. A nickel/titanium bilayer was sputtered onto the cilia part of the microrobot to ensure magnetic actuation and biocompatibility. T...

Recent developments in brushless dc motors and their drives have provided the technology to build electromechanically actuated primary controls. As a result, they have been proposed for ground, aerospace and (recently) marine applications. In this paper, previous architectures in an all-electric aircraft actuation control surface system will be proposed for an all-electric marine system. To ove...

This paper presents the modeling, design, fabrication and measurement of MEMS-enabled continuously tunable evanescent-mode electromagnetic cavity resonators and filters with very high unloaded quality factors (Qu). Integrated electrostatically-actuated thin diaphragms are used for the first time for tuning the frequency of the resonators/filters. An example tunable resonator with 2.6:1 (5.0 − 1...

Magnetic nanoparticles (MNPs) are effective drug carriers. By using electromagnetic actuated systems, MNPs can be controlled noninvasively in a vascular network for targeted drug delivery (TDD). Although drugs can reach their target location through capturing schemes of MNPs by permanent magnets, drugs delivered to non-target regions can affect healthy tissues and cause undesirable side effects...

in this paper the design of a biped robot actuated with shape memory alloy (sma) springs with minimum degrees of freedom is presented. sma springs are a class of smart materials that are known for their high power to mass and volume ratios. it was shown that utilizing spring type of smas have many advantages as large deformation, smooth motion, silent and clean movement compared to ordinary typ...

Magnetically-actuated Micromirrors as Micro-electromechanical devices have exhibited their superiority over other magnetic sensing techniques in terms of high sensitivity and high spatial resolution, which is favoured not only by quantitative measurement but also imaging of magnetic field distribution. In our research into magnetic field sensing and imaging, a 2D magnetic field sensing system w...

In this study, a magnetic spiral microrobot is proposed for tasks such as diagnosis, drug delivery, and minimally invasive surgery. It has a compact structure with a wireless power supply, low voltage, and a long working time. The microrobot is comprised of a spiral outer shell based on the Archimedes screw structure and an O-ring magnet for an actuator. The Archimedes screw structure produces ...

The modulated scattering technique is based on the use of reconfigurable electromagnetic scatterers, structures able to scatter and modulate an impinging electromagnetic field in function of a control signal. The modulated scattering technique is used in a wide range of frequencies up to millimeter waves for various applications, such as field mapping of circuits or antennas, radio-frequency id...
