Multifunctional organic shockproof flexible sensors based on a composite of nickel phthalocyanine colourant, carbon nanotubes and rubber created with rubbing‐in technology

Abstract

An organic multifunctional sensor based on a composite of nickel phthalocyanine colourant, multi-walled carbon nanotubes and rubber is investigated in this work. The whole surface-type device was fabricated over rubber substrate with rubbing-in technology, including multi-walled carbon nanotubes-based electrodes. The proposed shockproof and flexible sensor is investigated in terms of its electric parameters, that is, its resistance and impedance, while varying the humidity (42%-90% relative humidity), frequency (0.1-200 kHz) and temperature (30-68°C). The effect of each parameter is explained in depth to enhance the physics behind each outcome. The results demonstrate that impedance and resistance decrease with increases in temperature and humidity, while the sensitivity of the device decreases with an increase in frequency. These types of devices can be utilised by the medical industry for monitoring the humidity and temperature of patients while undergoing physiotherapy treatment.How to cite this article: Asghar U, Karimov KS, Ibrahim MA, Fatima N.

Stretchable Strain Sensor with Small but Sufficient Adhesion to Skin

“…Promising applications of these stretchable strain sensors include health monitoring, human motion detection, and human-machine interfaces [ 5 , 11 , 12 , 21 , 22 , 23 , 24 , 25 , 26 , 27 ] in which the sensors are attached to the skin. Sensors with sufficient stretchability can measure characteristics such as muscle movement, joint movement, heartbeat, and respiration, while maintaining good contact with the skin.…”
