Friend, Not Foe: Lowered Tissue Reactivity to Long‐Term Polyimide Implants

Advanced Science, EarlyView.
The choice of optimal neural probe designs remains a major challenge in the field of neurotechnology. This study investigated the biocompatibility of several probe variations, including material, thickness, width, and implantation strategy. It highlights the clear advantage of soft polyimide probes over stiff silicon probes for better device ...

Boosting Ferroelectricity: 2D and Polymer Ferroelectric Hybrids Enabling Ambipolar Nonvolatile MoS2 Memory Transistor

Advanced Science, EarlyView.
Two‐dimensional CuInP2S6 nanosheets are incorporated into a P(VDF‐TrFE) matrix to induce polarization‐cooperative ferroelectric coupling. The resulting P(VDF‐TrFE)/CuInP2S6 hybrid film exhibits reinforced ferroelectric ordering and reduced coercive electric fields compared with pristine P(VDF‐TrFE).

A Versatile‐Designable Framework for Active and Programmable Shape‐Morphing Soft Matter Systems: From Inverse Design to Closed‐Loop Control

Advanced Science, EarlyView.
A versatile framework integrates addressable electrothermal actuation and strain‐constraint mechanisms to construct programmable shape‐morphing soft matter systems. By combining an analytical inverse design strategy for high‐fidelity 3D surface reconstruction with deep learning‐based closed‐loop control, this approach enables zero‐energy shape locking,

Rigid Body Cable for Virtual Environments

IEEE Transactions on Visualization and Computer Graphics, 2008
The present paper addresses real-time simulation of cables for virtual environments. A faithful physical model based on constrained rigid bodies is introduced and discretized. The performance and stability of the numerical method are analyzed in details and found to meet the requirements of interactive heavy hoisting simulations.

How to Make a Square Grid Framework with Cables Rigid

SIAM Journal on Computing, 2000
Given a directed graph \(G=(V,E)\) and a partition \(\mathcal P\) of its vertex set \(V\) into color classes we ask for a minimum set of directed edges \(F\) such that \((V,E \cup F)\) is strongly connected and no edge in \(F\) has both endpoints in the same color class.

Coupled dynamics of flexible cables and rigid end-effector for a cable suspended robot

2006 American Control Conference, 2006
An important application of cable-suspended robots is in long-reach manipulation tasks. The usual assumption of rigid cables is not valid in these situations. The flexibility of cables needs to be included during modeling of residual motion of the manipulator after a gross motion has been made.
