Boron Doped Laser-Induced Graphene: A Suitable Substrate for Flexible and Wearable Sensor and Supercapacitor

In this letter, a new approach for the development of boron-doped laser-induced gra-phene (LIG) employing a blue visible light laser is presented. The doped graphitized electrode shows good electrical conductivity compared with bare LIG. The synthesized substrate is flexible and wearable, making it appropriate for different relevant applications, such as supercapacitors and sensing. Morphological analysis techniques, such as SEM and EDX, are employed for material characterization. Doped LIG shows potential for energy storage and physical sensors. Cyclic voltammetry (CV) and galvanostatic charge-discharge (GCD) techniques are employed to characterize the electrochemical characterization of the supercapacitor. These techniques assess the electrochemical performance of the devices. Electrical characterization is utilized in physical sensor characterization.
