Wearable multimode sensor with a seamless integrated structure for recognition of different joint motion states with the assistance of a deep learning algorithm.

Accurate motion feature extraction and recognition provide critical information for many scientific problems. Herein, a new paradigm for a wearable seamless multimode sensor with the ability to decouple pressure and strain stimuli and recognize the different joint motion states is reported. This wearable sensor is integrated into a unique seamless structure consisting of two main parts (a resistive component and a capacitive component) to decouple the different stimuli by an independent resistance-capacitance sensing mechanism.

[Preparation of cationic dextran microspheres loaded with tetanus toxoid and study on the mechanism of protein loading].

The aim of this study is to prepare cationic biodegradable dextran microspheres loaded with tetanus toxoid (TT) and to investigate the mechanism of protein loading. Positively charged microspheres were prepared by polymerization of hydroxylethyl methacrylate derivatized dextran (dex-HEMA) and dimethyl aminoethyl methacrylate (DMAEMA) in an aqueous two-phase system. The loading of the microspheres with TT was based on electrostatic attraction.

Combustion oxidization synthesis of unique cage-like nanotetrapod ZnO and its optical property.

Cage-like nano-tetrapod ZnO is a novel structure, which was successfully synthesized by combustion oxidation at 850 degrees C. No catalyst or carrier gases were used. Thorough SEM and TEM analyses revealed that the linking legs of the tetrapod ZnO can have or not interface.
