**8. Conclusions and future trends**

Laser beam-material interactions induce the controlled changes in the physical and chemical properties of the electrode materials for MSCs. In addition, the smaller spatial resolution obtained using the tightly controlled focus spot can lead to the enhancement of specific volume load per unit area resulting in efficient storage of electrolyte ions within the layers of the electrodes. The desired electrode patterns fabricated using the writing process enable the supercapacitor features to be included in any substrates with the proper choice of electrolytes. The improvement of further energy density obtained in laser-scribed supercapacitors using advanced techniques like super-resolution fabrication [41] along with the implementation of multifocal parallel array fabrication [42] can offer the fabrication in short period of time and deployment of self-powered autonomous systems in the next-generation technology like buildings, sensors, imaging, etc.
