High speed reciprocating cutter bar design and developments

open access: yes, 2020
Formal methods are needed in correctly predicting the performance of reciprocating cutter bars. Theoretical, laboratory, and field methods were investigated to predict the performance of four cutter bars, two production and two prototype. The theoretical analysis was implemented using a MathCAD model based on prior works, and generated performance ...

Ti6Al4V‐Bioglass‐Copper Composites for Load‐Bearing Implants

open access: yesAdvanced Healthcare Materials, EarlyView.
We have designed and manufactured a novel Ti64‐based composite by adding 45S5 bioglass (BG) and copper (Cu). Adding BG on titanium improves wear resistance and biocompatibility, whereas Cu addition improves mechanical strength while providing inherent lifelong bacterial resistance.

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

open access: yesAdvanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

open access: yesAdvanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

The Dynamic Energy Band Model of Contact‐Separation and Sliding Mode Triboelectric Charging of Polymers at the Metal‐Polymer Interface

open access: yesAdvanced Science, EarlyView.
Triboelectric charge generation at polymer‐metal interfaces arises from the interplay of intra‐ and inter transformation reactions of mechanochemically generated species, physical properties of polymers, environmental conditions. The direction and the magnitude of electron transfer between metal and polymer are dynamically governed by the relative ...
