High-performance flexible pressure sensors have an essential application in many fields such as human detection and human−computer interaction. Herein, on the basis of the dielectric layer of a bionic komochi konbu structure, we propose a low-cost and novel capacitive sensor that achieves high sensitivity and stability over a broad range of tactile pressures. Further, the flexible and durable electrode layer of the transparent junctionless copper/nickel-nanonetwork was prepared based on electrospinning and electroless deposition techniques, which ensured high bending stability and high cycle stability of our sensor. More importantly, because of the sizeable protruding structure and internal micropores in the elastomer structure we designed, the inward curling of the protruding structure and the effectual closing of the micropores increase the effective dielectric constant under the action of the compressive force, improving the sensitivity of the sensor. Measured response and relaxation time (162 ms) are 250 times faster than those of a conventional flat polydimethylsiloxane capacitive sensor. In addition, the fabricated capacitive pressure sensor demonstrates the ability to be used on wearable applications, not only to quickly recognize the tapping and bending of a finger but also to show that the pressure of the finger can be sensed when the finger grabs the object. The sensors we have developed have shown great promise in practical applications, such as human rehabilitation and exercise monitoring, as well as human−computer interaction control.

“…On the other hand, the morphology of the synthesized nanoparticles plays a fundamental role in its biological activity [21][22][23][24]. Although the morphology of the AgNPs was not characterized, what was found in the study represents an important contribution to the green synthesis, leaving pending further studies, not only the characterization of the AgNPs, but also their biological potential.…”

La síntesis de nanopartículas de plata (AgNPs) ha tenido un impacto positivo en las ciencias biomédicas, gracias a sus diversas potencialidades bilógicas, entre las que destacan su actividad antimicrobiana e interacción in vitro con diversas drogas quimioterapéuticas. El estudio tuvo como objetivo la síntesis de AgNPs, empleando extractos acuosos de cálices, hojas y semillas de un cultivo orgánico de Hibiscus sabdariffa y una solución de nitrato de plata (AgNO3). A cada extracto se le determinó la concentración de compuestos fenólicos totales y flavonoides, por los métodos de Folin-Ciocalteu y Marinova respectivamente, esto con el propósito de garantizar la calidad y contenido de compuestos con capacidad reductora. Se optimizaron las condiciones de síntesis de AgNPs, referente a volumen y concentración de AgNO3, volumen de extracto (cálices, hojas y semillas), pH, tiempo y temperatura de calentamiento, empleando el programa estadístico StatGraphics. Los análisis arrojaron una concentración de 17.42±0.12 mg GAE/g (cálices), 9.03±0.91 mg GAE/g (hojas) y 11.32±0.36 mg GAE/g (semillas). Los picos máximos de absorción se obtuvieron a 424 nm para todos los tres extractos, con absorbancias de 1.5240±0.32 =30- 32 nm (AgNPs- cálices), 0.5674±0.24=12-14 nm (AgNPs-hojas) y 0.7641±0.18=18-20 nm (AgNPs-semillas) . Los hallazgos del estudio están relacionados con la variación de compuestos fenólicos en las diferentes partes de H. sabdariffa, lo que condiciona el rendimiento de síntesis de AgNPs.el presente estudio representa un valioso aporte en la “Síntesis Verde”, representando el primer estudio en Venezuela en la que se sintetizan AgNPs a parir de H. sabdariffa

More than five decades have been invested in understanding glucose biosensors. Yet, this immensely versatile field has continued to gain attention from the scientific world to better understand and diagnose diabetes. However, such extensive work done to improve glucose sensing devices has still not yielded desirable results. Drawbacks like the necessity of the invasive finger pricking step and the lack of optimization of diagnostic interventions still need to be considered to improve the testing process of diabetic patients. To upgrade the glucose-sensing devices and reduce the number of intermediary steps during glucose measurement, fourth-generation glucose sensors (FGGS) have been introduced. These sensors, made using robust electrocatalytic copper nanostructures, improve diagnostic efficiency and costeffectiveness. This review aims to present the essential scientific progress in copper nanostructure-based FGGS in the past ten years (2010 -present). After a short introduction, we presented the working principles of these sensors. We then highlighted the importance of copper nanostructures as advanced electrode materials to develop reliable real-time FGGS. Finally, we cover the advantages, shortcomings, and prospects for developing highly sensitive, stable, and specific FGGS.
