Article Synopsis
- Developing adaptive materials that can change shape and interact with their environment is a complex challenge in design.
- This research introduces new strain-engineered materials that use micro-origami technology to create shapes that can change in response to stimuli like chemicals and electricity.
- Two examples of their application include a foldable supercapacitor that boosts energy efficiency and a dynamic bio-adaptive device that could lead to advanced smart implants in healthcare.
Existing electronically integrated catheters rely on the manual assembly of separate components to integrate sensing and actuation capabilities. This strongly impedes their miniaturization and further integration. Here, we report an electronically integrated self-assembled microcatheter.

- Analytical platforms using impedance spectroscopy offer a non-invasive way to study single cells and their environment, vital for understanding disease-related functions.
- The newly developed "sensor-in-a-tube" combines rolled-up platinum microelectrodes to analyze human monocytes and their extracellular medium activated by liposaccharides (LPS).
- This innovative sensor successfully detects the relationship between cell activation states and the electrical properties of their surroundings without needing any labeling or surface modifications, making it a valuable tool for diagnosing immune-related diseases.
In this article we present a relevant strategy for a non-trivial time-programmed release of water-soluble macromolecules from biocompatible μ-containers. The system is based on self-scrolled chitosan acetate (CA) fibers, encapsulated in a poly(dimethylsiloxane) matrix. Mass transfer between a fiber and the external environment takes place via the only opened extremity of the fiber.

The collapse of the elastomer after oil extraction generates differential stress in the films that is manifested through their out-of-plane deformation. The curvature κ of narrow stripes of the bilayer, which is composed of layers of approximately equal thicknesses and elasticity moduli, is satisfactorily described by the simple relationship κ = 1.
