Electrochemical measurements were carried out in a conventional three-electrode cell (from Metrohm) powered by an electrochemical system comprising of AUTOLAB system with PGSTAT302N (Eco Chemie, Utrecht, The Netherlands). The system was run on a PC using NOVA 1.7 software. Saturated Ag/AgCl was used as the reference electrode and the counter electrode (also known as auxiliary electrode), which is usually made of an inert material, platinum. All potentials were measured with respect to the Ag/AgCl which was positioned as close to the working electrode as possible by means of a luggin capillary. GCE (Azar electrode Co., Urmia, Iran) was used as the working electrode. Atomic force microscopy (AFM) experiments were performed in a contact mode by Nanowizard AFM (JPK Instruments AG, Berlin, Germany) mounted on Olympus Invert Microscope IX81 (Olympus Co., Tokyo, Japan). The transmission electron microscope (TEM) images were obtained on Leo 906, Zeiss (Germany). UV–vis spectroscopy was performed by Spectro UV–vis 2502 (Cecil, Cambridge, UK). X-ray powder diffraction (XRD) measurements were performed using Siemens, D500 (Germany). Dynamic light scattering (DLS) was obtained using Malvern 3500 ZS. Spectrofluorimetery test was performed using Jasco, FP-750 (Tokyo, Japan).

Electrochemical measurements were conducted using a conventional three-electrode cell (from Metrohm), containing an Ag/AgCl-saturated KCl (from Metrohm) as reference, platinum wire as counter electrodes and GCE (d = 2 mm) as working electrode. It was powered by an electrochemical system comprised of an AUTOLAB system with PGSTAT 302N (Eco Chemie, Utrecht, The Netherlands). The system was run on a PC using NOVA 1.11 software.
The surface morphology of the electrode surface was characterized by high-resolution field emission scanning electron microscope (FE-SEM, Hitachi-SU8020, Czech) with an operating voltage of 3 kV, and chemical compositions of the GNP were analyzed by an energy dispersive spectroscopy (EDX) coupled with the FE-SEM equipment.

Electrochemical experiments were performed in a three-electrode cell (2 mL), containing the glassy carbon electrode (GCE, geometric area 0.00785 cm2) as the working electrode, a Pt wire counter electrode, and an Ag/AgCl (3.0 M KCl) reference electrode (Metrohm Autolab, Utrecht, The Netherlands), using a potentiostat/galvanostat µ-Autolab system (Metrohm Autolab, Utrecht, The Netherlands). Before each use, the surface of the GCE was cleaned with diamond spray and polishing paper (Kemet, High Wycombe, UK).
The pH measurements were carried out with a CRISON 2001 micro pH-meter (Crison Instruments SA, Barcelona, Spain) at room temperature.

Integrated Contact Separation Triboelectric Nanogenerator for Breath Sensing

The integrated contact separation triboelectric nanogenerator (CS-TENG) utilized to power the breath sensor consisted of FTO glass and Kapton with an aluminum tape behind it, serving as the back contact layer. A homemade machine was designed to investigate the performance of FTO/Kapton-based TENG in mechanical harvesting energy, as depicted in Fig. S1 . A linear electric motor capable of controlling the applied force via the stepping position was developed and used during the electrical measurement. The behavior of the CS-TENG was investigated by adjusting the motion of the two electrodes using gauges on a vertical contact-separation tapping device at different frequencies ranging from 1 to 4 Hz, and applying a force of 6 N to bring the two surfaces into contact, which leads to the induction of triboelectric charge. The maximum spacing distance of the electrodes was 2 cm, and the effective contact area of the TENG was 8 cm × 8 cm. The voltage and current of the TENG-based system based were measured using a DSO1022A digital oscilloscope (Agilent Technologies) and a potentiostat–galvanostat (µAuto-lab system, Metrohm), respectively.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
