Rotary 4D Printing of Programmable Metamaterials on Sustainable 4D Mandrel
Advanced Materials Technologies, EarlyView.The paper introduces open, rotary 4D printing of programmable tubular metamaterials. It presents an open, non‐planar path‐to‐G‐code pipeline and shape‐changing rotary mandrel that enable support‐free fabrication and multi‐stimuli actuation. Experiments and FEA validate the mentioned features and stress redistribution.

Everolimus-eluting stents or bypass surgery for multivessel coronary disease.
New England Journal of Medicine, 2015 BACKGROUND Results of trials and registry studies have shown lower long-term mortality after coronary-artery bypass grafting (CABG) than after percutaneous coronary intervention (PCI) among patients with multivessel disease.

Advanced Robotics Research, EarlyView.Integrating proprioceptive capabilities in balloon‐type robots enhances safe human–machine interactions. Traditional pressure estimates are inadequate due to nonlinear relationships. Instead, embedding stretchable sensors effectively measures deformation. This design optimizes sensor geometry to minimize damage risks.
