Creation and Analysis of a Respiratory Sensor Using the Screen-Printing Method and the Arduino Platform

Abstract

The aim of this paper is to present novel highly sensitive and stretchable strain sensors using data analysis to report on human live parameters using the Arduino embedded system as a proof of concept in developing new and innovative solutions for health care. The article introduces the solution of textile sensor origination with electrical resistance measurement using the mobile Arduino microcontroller in the designed/elaborated textile printed sensor. The textile sensor was developed by the screen printing technique based on the water dispersion of carbon nanotubes during printing composition. By stretching and squeezing the T-shirt during breathing, the electrical resistances of the printed sensor were changed. The measured resistance corresponded to the number of breaths of the person wearing the T-shirt. The microcontroller calculated the number of breaths as a number of electrical resistance peaks, which then led to monitoring human live parameters.

Inkjet-Printed Multiwalled Carbon Nanotube Dispersion as Wireless Passive Strain Sensor

“…Though thin film-based CNTs showed high potentials for strain sensing applications, temperature effect, stability, and linearity are some unsolved problems [ 15 , 16 , 17 ]. Thin films composed of CNTs are made using a variety of deposition methods, such as drop-casting, spin-coating, spray-coating, dielectrophoresis [ 18 ], and screen printing [ 19 ], each of which has advantages and disadvantages that are unique [ 20 , 21 , 22 ]. These deposition methods enable tailored CNT dispersion deposition for an array of applications by providing fine control over the film thickness and uniformity.…”

The Influence of the Washing Process on the Impedance of Textronic Radio Frequency Identification Transponder Antennas

“…Progress in various fields of technology and its interdisciplinary uses cause an increase in the popularity and accessibility of intelligent technologies. In recent years, smart wearable devices used, among others, in the medical [ 1 , 2 , 3 , 4 , 5 , 6 ], sports [ 7 , 8 , 9 , 10 ] or military and emergency services [ 11 , 12 ] sectors have become extremely popular. In order to meet the growing requirements for the comfort of using such devices, designers’ attention has been turned towards intelligent textiles and electronic textiles (e-textiles) [ 13 , 14 ].…”
