Descrição:
The development of triboelectric nanogenerator technology has many benefits across various fields, particularly in healthcare applications; herein, a concise single‐electrode pulse sensor with a high output performance at a reasonable cost is suggested. The device is made up of a polydimethylsiloxane film with a spacer‐created trench structure stacked on top of a graphene‐coated polyethylene terephthalate film. A comprehensive examination of sensor fabrication together with material and electrical characterization is explained. The entire study is carried out using a graphene–silver composite electrode device, giving an output performance of ≈1.66 and ≈2.9 V for tapping movement in plain and microstructured triboelectric surfaces, respectively; however, for the graphene electrode device, the output obtained is ≈5.5 V. This wearable sensor can successfully extract the typical human wrist pulse, which displays the pressure wave from the radial artery in the range of ≈5 V with the help of an exemplary amplifier circuit and will be suitable to integrate with IoT. The single‐electrode triboelectric nanogenerator flexible sensor is made up of a polydimethylsiloxane film with a spacer‐created gap stacked on top of a graphene‐coated polyethylene terephthalate film, used for the wrist pulse sensing application giving an output of ≈5 V with the help of a good amplifier circuit and in future can be integrated with IoT for disease diagnosis.
