“…To restore potential equilibrium, electrons move from the top to the bottom electrode, creating an electric current pulse with an opposite polarity. Hence, the periodic application and removal of a constant force give rise to positive and negative charge pulses in the system [16,[29][30][31].…”

A high-performance triboelectric nanogenerator (TENG) has been developed for breath sensing applications, utilizing tribopositive electrospun nylon-6 nanofibers and tribonegative fluorinated ethylene propylene (FEP). The optimization towards the development of electrospun nylon-6-based TENG includes a range of factors such as the applied force and frequency on tribo responses, the thickness of the fiber mat, the concentration of nylon-6 in the fiber mats, and the selection of the tribonegative material for pairing with nylon-6 nanofiber. Among these parameters, the nanofiber prepared with 18 wt% nylon-6, characterized by a uniform fiber distribution, the highest surface area of 55.69 m2/g, and an optimal thickness of 0.169 mm, demonstrated excellent TENG performance, among others. The TENG module constructed using nanofiber in a 4 cm2 area showed the TENG responses of more than 30 μA short-circuit current, 200 V open-circuit voltage, and 90 nC charge when hand-pressed. It achieved a substantial power density of 890 mW/m2 at 20 MΩ by applying a constant force of 10 N at a 10 Hz frequency. Charging a 1 μF capacitor to approximately 30.1 V in just 30 seconds highlights the potential of electrospun nylon-6 as a promising material for nanogenerator energy harvesting and sensing applications. The TENG device was found to be sufficient to power small, portable electronics such as LEDs and digital watch displays. A wearable belt was fabricated to showcase its breath-sensing capabilities by pairing it with FEP. The microcontroller connected to the TENG in the wearable belt is used to analyze the output produced through breathing patterns, subsequently activating a buzzer and LED by the nature of the breathing.

“…To this mixture, a curing agent (TEOS) and accelerator (DBTDL) with a weight ratio of PDMS:TEOS:DBTDL at 100:10:1 was added and homogenized well. [10,24] The filler-incorporated PDMS solution was poured into a petri dish and cured for 4 h at room temperature. In order to compare and evaluate the effect of filler in the PDMS matrix on TENG performances, a neat PDMS film without any filler was prepared.…”

Energy harvesting triboelectric nanogenerators (TENGs) to scavenge unused mechanical energy have received significant attention in this decade. Herein, the development of reduced graphene oxide (rGO):polypyrrole (PPy) hybrid‐modified polydimethylsiloxane (PDMS) as TENG for various device applications is reported. The bulk of PDMS is altered by different fillers such as rGO, PPy, and the binary hybrids of rGO and PPy with varying weight ratios. Among various PDMS composites, 1 wt% of 1:8 rGO:PPy–PDMS composite exhibits higher TENG responses than other PDMS composite. The superior TENG performances of 1 wt% 1:8 rGO:PPy–PDMS composite are attributed to the formation of intensified negative charges inside the PDMS matrix. This charge intensification in the composite is due to various mechanisms, including the charge trapping ability of rGO:PPy filler, microcapacitor formation by introducing hybrid filler in the system with proper conducting networks, and the electron‐donating nature of PPy conducting polymer. A 3D stacked device proposed using 1 wt% 1:8 rGO:PPy–PDMS composite delivered a short‐circuit current of 16 μA and an open‐circuit potential of 60 V by simple palm pressing. Also, the ability of the stacked device for charging/powering portable devices and light‐emitting diodes is demonstrated.

“…Then the TEOS curing agent and DBTDL accelerator were added to the sonicated mixture maintaining the weight ratio of PDMS : TEOS : DBTDL at 100 : 10 : 1. The ultrasonicated PDMS dispersion was solution-casted in a Petri dish and cured at room temperature for 24 h. 28 A neat PDMS film sample without nanofillers was also prepared for comparison purposes. The GO/CP-PDMS samples are named 1 : 4 GO : PANI-PDMS, 1 : 8 GO : PANI-PDMS and 1 : 12 GO : PANI-PDMS, 1 : 4 GO : PPy-PDMS, 1 : 8 GO : PPy-PDMS, 1 : 12 GO : PPy-PDMS, and Pristine PANI-PDMS, Pristine PPy-PDMS, GO-PDMS, and Pure PDMS.…”
