Amorphous carbon material of daily carbon ink: emerging applications in pressure, strain, and humidity sensors

Abstract

Carbon based materials have been widely used in various sensors. In addition to widely reported graphene, carbon nanotubes and their composites, low-cost amorphous carbon materials are also sought after. In...

Tailoring selenium vacancies in MoSe2 through oxygen passivation for room-temperature NO2 sensing enhancement

“…The relative standard deviation of the response in the reproducibility test was calculated to be 5.1%. Further, the stability to humidity change is important for the sensor working at room temperature; 64–66 the MoSe 2 –SeVO2 sensor exhibited good stability in the humidity range from 30% to 70% changes (Fig. S12†).…”

Multifunctional small biomolecules as key building blocks in the development of hydrogel-based strain sensors

“…Strain sensors are used in various applications such as human–machine interfaces, robotic smart skins, health care monitoring, and bio-integrated devices. 1,2 Paper-based strain sensors can be classified into three types based on their working modes: bending, 3,4 pressure, 5,6 and tensile 7,8 sensors. However, only bending and pressure sensors are typically considered for flexible paper-based strain sensors due to the limited stretchable properties of paper, 4,9,10 which limit the potential of sensing to only small strain ranges.…”

An Ultrastretchable Gradient Ionogel Induced by a Self-Floating Strategy for Strain Sensing

“…Therefore, ionogels have fostered an increasing interest in flexible sensors, such as pressure sensors, , gas sensors, , humidity sensors, temperature sensors, , and strain sensors − in recent years. Flexible strain sensors in particular, which monitor the mechanical deformation of substrates, have attracted considerable attention in healthcare and human motion detection applications; − the main type of strain sensors is the resistance type . Earlier this year, Zhao et al reported highly conductive, polyurethane-based ionogels for monitoring physiological signals.…”

“…Flexible strain sensors in particular, which monitor the mechanical deformation of substrates, have attracted considerable attention in healthcare and human motion detection applications; 16−19 the main type of strain sensors is the resistance type. 20 Earlier this year, Zhao et al 21 reported highly conductive, polyurethane-based ionogels for monitoring physiological signals. They achieved high conductivities by introducing carboxyl groups into the hard segments of the polyurethane, which created ion exchange sites.…”
