Multiphoton‐Printed Microrobotic Arrays Powered by Discrete, Monolithically Integrated Hydrogel Actuators

Advanced Robotics Research, EarlyView.
Functional surfaces are investigated as a foundation for reconfigurable microscale systems with sensing and actuation capabilities. Advances in additive manufacturing enable our development of planar arrays of hybrid‐material, compliant microdevices that convert environmental stimuli into programmed motion and visual responses.

GIGAHERTZ SCANNING ELECTRON ACOUSTIC MICROSCOPY [PDF]

, 2017
In Scanning Electron Acoustic Microscopy (SEAM) an electron beam with the beam current impacting a target site is modulated at acoustic or ultrasonic frequencies. The absorbed energy of the electrons results in a time-varying thermal expansion that leads

Quantitative Scanning Electron Acoustic Microscopy of Silicon [PDF]

, 1993
So far results of scanning electron acoustic microscopy (SEAM) have retained a widely qualitative meaning only due to the enormous uncertainty in understanding sound generation and contrast mechanisms in SEAM micrographs.

Analytical evaluation of intact human tissues using mid-frequency scanning acoustic microscopy at the mesoscopic scale

Journal of Analytical Science and Technology
Conventional histological examination requires irreversible sectioning, consuming tissue and precluding three-dimensional analysis. This limitation is particularly problematic for archival specimens and forensic investigations.

Autonomous Navigation of Pollen‐Inspired Magnetic Microrobots for Biomedical Applications

Advanced Robotics Research, EarlyView.
A sunflower pollen‐inspired magnetic microrobot enables controlled rolling navigation in vessel‐like environments. Its open geometry reduces hydrodynamic drag, while vision‐based closed‐loop control, shortest‐path planning, and reinforcement learning support target‐reaching and maze navigation with microrobot‐scale accuracy, highlighting a route toward
