Smart biomaterials hold great potential for many biological applications in regenerative medicine. In this field, we aim to develop a novel electro-responsive PolyPhosphoEster (PPE) based hydrogel. This hydrogel can transform electrical energy into conformational changes of the structure when exposed to an electrical field (Fig. 1b). These hydrogels have high potential, allowing development of ...

Stretchable hydrogel electronics and devices are designed by integrating stretchable conductors, functional chips, drug-delivery channels, and reservoirs into stretchable, robust, and biocompatible hydrogel matrices. Novel applications include a smart wound dressing capable of sensing the temperatures of various locations on the skin, delivering different drugs to these locations, and subsequen...

This paper reports development of a novel, flexible hydrogel based capacitive pressure sensor. It features a simple design of hydrogel thin film sandwiched between two gold electrodes. The sensor shows linear increase in output with increase in pressure. The microporous network of hydrogel enables high water retention while its flexible and stretchable structure ensures usage over large areas. ...

Hydrogel Smart Windows In article number 2211716, Xiancai Jiang, Jun Fu, and co-workers report a novel thermochromic hydrogel-based smart window for all-weather building-temperature regulation in diverse climates. The hydrogel windows spontaneously transform from transparent to opaque upon temperature changes. outdoor solar radiation summer indoor thermal winter are both regulated by the modula...

Here described is a phenylboronic acid (PBA) based glucose-responsive hydrogel operating under physiological pH and temperature, a material potentially applicable to a totally synthetic smart insulin delivery system to treat diabetes.

Multi-functional supramolecular hydrogels have emerged as smart biomaterials for diverse biomedical applications. Here we report a multi-functional supramolecular hydrogel formed by the conjugate of the bioactive GRGDS peptide with biaryltetrazole that is the substrate of photo-click reaction. The hydrogel was used as a biocompatible matrix to encapsulate live cells for 3D culture. The presence...

The elastic shear modulus G and swelling pressure ω are studied for a basic, pH-responsive hydrogel synthesized by crosslinking copolymerization of co-monomers hydroxypropyl methacrylate and N,N-dimethylaminoethyl methacrylate with crosslinker tetraethylene glycol dimethacrylate. Under normal conditions of use as a "smart" material, hydrogel swelling ratio Q and pH vary simultaneously, but here...
