Design, Modeling, and Control of a Soft Robotic Diaphragm‐Assist Device in a Respiratory Simulator

open access: yesAdvanced Intelligent Systems, EarlyView.
A soft robotic diaphragm‐assist device using fabric‐based pneumatic actuators with a 2‐step control system to optimize synchronization and support is introduced. This system can detect the initiation of breathing to trigger assistance and regulate pressures to provide the correct level of inhalation augmentation. Validation and testing are completed on

Electronic‐Free Particle Robots Communicate through Architected Tentacles

open access: yesAdvanced Intelligent Systems, EarlyView.
This work introduces a new class of particle robots that communicate without any electronic components. Their communication protocols are encoded in the geometry of their tentacles are and realized solely through physical contact. Building on these simple communication schemes, electronic‐free particle robots can achieve a range of collective ...

Optimization of Transformable Multiple Impeller (AM Impeller) for Highly Viscous Fluids

open access: yesJournal of Advanced Manufacturing and Processing, EarlyView.
ABSTRACT Mixing performance in a laminar flow with a mixing Reynolds number less than 10 is greatly affected by the geometry of the impeller blades, and how to generate axial flow is important. The authors developed a new AM impeller with a low production cost by combining simple pitched paddle impellers in multiple stages.

3D‐Printable Polymer Composites With Unmodified Boron Nitride for Thermal Management in Flexible Electronics

open access: yesJournal of Applied Polymer Science, EarlyView.
ABSTRACT Flexible high‐performance electronics are facing the challenge of managing increasing thermal loads in the latest devices. This study presents a one‐step method for 3D printing flexible boron nitride (BN) polymer composites via vat photopolymerization, enhancing thermal conductivity by 270% to 0.8 W m−1 K−1 and improving dielectric properties (
