Robotic Materials With Bioinspired Microstructures for High Sensitivity and Fast Actuation

Advanced Science, EarlyView.
In the review paper, design rationale and approaches for bioinspired sensors and actuators in robotics applications are presented. These bioinspired microstructure strategies implemented in both can improve the performance in several ways. Also, recent ideas and innovations that embed robotic materials with logic and computation with it are part of the

Piezoelectric devices for vibration suppression: Modeling and application to a truss structure [PDF]

For a space structure assembled from truss members, an effective way to control the structure may be to replace the regular truss elements by active members. The active members play the role of load carrying elements as well as actuators.

Structural control by the use of piezoelectric active members [PDF]

Large Space Structures (LSS) exhibit characteristics which make the LSS control problem different form other control problems. LSS will most likely exhibit low frequency, densely spaced and lightly damped modes.

Rigid Hollow Microparticles for Enhanced Focused Ultrasound Treatment Under Optoacoustic Guidance

Advanced Science, EarlyView.
By combining focused ultrasound (FUS) and acoustically active hollow borosilicate microparticles (HBMPs), we demonstrate tunable control over interparticle dynamics and their localized thermal energy deposition. Modulation of acoustic frequency and particle concentration tailors the energy delivery, allowing adaptive, material‐based regulation of ...

Peptide Sequence Programmed Piezoelectric Response by Supramolecular Self‐Assembly

Advanced Science, EarlyView.
In this study, hydrophobic tripeptides are explored as building blocks for stable piezoelectric crystals. Tripeptides with phenylalanine at the central position self‐assembled into uniform, thermally stable crystals. Piezoresponse force microscopy reveals a high effective piezoelectric coefficient of 24.0 pC N−1, attributed to asymmetric molecular ...
