A Universal Interfacial Strategy Enabling Ultra‐Robust Gel Hybrids for Extreme Epidermal Bio‐Monitoring

چکیده

A seamless and tough interface to integrate incompatible/immiscible soft materials is highly desired for flexible/wearable electronics many devices with multi-layer structures. Here, a surfactant-mediated interfacial chemistry introduced achieve interfaces in structures, an ultra-high toughness up ≈1300 J m−2 the architectural gel hybrid (AGH). The reversible noncovalent interactions efficiently dissipate energy at interface, thereby providing excellent durability. only decreases by ≈6.9% after 10 000 tensile cycles. This strategy can be universally applied systems various between interior hydrogel (PAA, PVA, PAAm, gelatin) exterior hydrophobic matter (ionogel, lipogel elastomer). AGH-based mechano-sensor presents high robustness stability wide range of conditions, including open air, underwater, solvents temperatures. Epidermal bio-monitoring, tactile trajectory, facial expression recognition are demonstrated using AGH sensors environments. rich set electrophysiological signals quality acquired.

Colloidal thermoresponsive gel forming hybrids.

Colloidal hybrids comprise organic and inorganic components and are attracting considerable attention in the literature. Recently, we reported hybrid anisotropic microsheets that formed thermoresponsive gels in polymer solutions [Liu et al., Langmuir, 25, 490, 2009]. Here, we investigate the composition and properties of these hybrid colloids themselves in detail for the first time. Three diffe...

An Interfacial Tensiometer for Universal Use

The important and fundamental works of Quincke, Hardy, McC. Lewis, Morgan, and lately Harkins and his collaborators have thrown much light on the behavior of liquids at interfaces, and it may seem hardly necessary to develop a new method in order to study this phenomenon, as those existing have reached a high degree of accuracy. However, if the values of the interfacial tensions of pure liquids...

A universal strategy for visually guided landing.

Landing is a challenging aspect of flight because, to land safely, speed must be decreased to a value close to zero at touchdown. The mechanisms by which animals achieve this remain unclear. When landing on horizontal surfaces, honey bees control their speed by holding constant the rate of front-to-back image motion (optic flow) generated by the surface as they reduce altitude. As inclination i...
