Triboelectric tactile sensor for pressure and temperature sensing in high-temperature applications.

Skin-like sensors capable of detecting multiple stimuli simultaneously have great potential in cutting-edge human-machine interaction. However, realizing multimodal tactile recognition beyond human tactile perception still faces significant challenges. Here, an extreme environments-adaptive multimodal triboelectric sensor was developed, capable of detecting pressure/temperatures beyond the range of human perception.

Lightweight and Mechanically Robust Cellulosic Triboelectric Materials for Wearable Self-Powered Rehabilitation Training.

Lightweight and robust self-powered wearable devices are of great importance in rehabilitation and medical assistance, but this places greater demands on the development of functional materials. In particular, a balance between reducing the weight of materials and enhancing their mechanical performance is urgently needed. Here, this study reports a design strategy based on a cross-scale strengthening mechanism, which endows triboelectric materials with mechanically robust properties, and can withstand more than 16,600 times its weight without any deformation.

The Effect of Water Co-adsorption on the Adsorption of Formaldehyde in Fe-HHTP-MOF Metal-Organic Materials.

Because of the existence of moisture in indoor air, it is still a serious challenge to capture formaldehyde indoors with the metal-organic material Fe-HHTP-MOF. To explore the relationship between the structure and performance of Fe-HHTP-MOF in dry and humid air, molecular dynamics simulation was used to study the adsorption amount of Fe-HHTP-MOF for formaldehyde and water under different temperatures and adsorption pressures, as well as the adsorption amount of Fe-HHTP-MOF for formaldehyde in the presence of both water and formaldehyde, and the differences in adsorption of formaldehyde and water by Fe-HHTP-MOF were compared and analyzed when water coexisted. The results show that under single-component isothermal adsorption, the hydrogen bond energy formed by Fe-HHTP-MOF adsorbing HO molecules is much greater than the van der Waals energy formed by adsorbing HCHO molecules.

A general strategy to achieve see-through devices through the micro-structuring of colored functional materials.

Irrespective of the specific see-through device, obtaining optimal transparency remains the primary goal. In this work, we introduce a general strategy to enhance the transparency of various see-through devices. We achieve this by structuring the colored functional materials into imperceptible three-dimensional mesh lines, addressing a common challenge in multi-layer structures where each layer causes a reduction in transparency due to their color or opacity.

Extraction, purification, structural characterization, and bioactivities of Radix Aconiti Lateralis Preparata (Fuzi) polysaccharides: A review.

Radix Aconiti Lateralis Preparata (Fuzi) polysaccharide (FZP) is a key bioactive macromolecule derived from the root of Aconitum carmichaeli Debx.
