Resumen

Los investigadores desarrollaron una novedosa arquitectura fibrosa magnética blanda para wearables avanzados y robótica blanda. Este material responde vectorialmente a campos magnéticos seguros, mejorando la seguridad y la fabricabilidad sin pre-magnetización.

Área de la Ciencia:

Ciencia de Materiales
Robótica Blanda
Ingeniería Textil

Sus antecedentes:

Los materiales magnetorreológicos (RM) ofrecen capacidades de respuesta vectorial para wearables y robótica blanda.
Los materiales de RM existentes a menudo requieren pre-magnetización o carga de imanes duros, lo que limita la seguridad y la fabricabilidad.

Objetivo del estudio:

Presentar una novedosa arquitectura fibrosa magnética blanda para materiales con respuesta a estímulos vectoriales.
Demostrar un marco de diseño jerárquico que supera las limitaciones de los materiales de RM existentes.

Principales métodos:

Diseño jerárquico que integra los niveles de material, fibra, hilo y tejido.
Utilización de propiedades magnéticas blandas y eje magnético fácil inducido por estiramiento en las fibras.
Empleo de efectos cooperativos inducidos por torsión en los hilos para la respuesta a nivel de tejido.

Principales resultados:

Se logró una auténtica capacidad de respuesta a estímulos vectoriales bajo campos magnéticos bajos y seguros sin pre-magnetización.
Se demostró la flexión, el endurecimiento, el cizallamiento y la compresión programables en textiles.
Se estableció una plataforma versátil para sistemas magneto-programables con una fuerte universalidad de materiales.

Conclusiones:

El diseño jerárquico resuelve las compensaciones entre el rendimiento del material de RM, la fabricabilidad y la seguridad.
Este enfoque permite una nueva generación de wearables adaptativos, sistemas hápticos y aplicaciones de robótica blanda.
Abre trayectorias futuras en modelado teórico, integración multiestímulo y arquitecturas textiles 3D.

Globular and Fibrous Proteins

Globular and Fibrous Proteins

Many proteins can be classified into two distinct subtypes - globular or fibrous. These two types differ in their shapes and solubilities.
Globular proteins are also known as spheroproteins and typically are approximately round in shape. They contain a mix of amino acid types and contain differing sequences in their primary structures. Globular proteins have many different functions, such as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be...

Fibrous Proteins

Fibrous proteins are either long and narrow proteins or assemble to form long and thin structures. They contain repetitive units and usually consist of either alpha helices or beta sheets and, in rare cases, a mix of both. The amino acids in the primary structure often consist of repeating amino acid sequences. The role of fibrous proteins is primarily structural. Many are located in the extracellular matrix and are present in connective tissues to impart strength and joint mobility. They are...

Structural Joints: Fibrous Joints

Structural Joints: Fibrous Joints

Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints.
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

The Sense of Self: Reflected Self-Appraisal and Social Comparison

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...
