19.1 Integration of harvesters in textiles and accessories

Piezoelectric textiles are revolutionizing wearable tech by turning everyday clothes into power sources. These smart fabrics use special materials that generate electricity when stretched or moved, allowing your outfit to charge devices as you go about your day.

From flexible fibers to screen-printed fabrics, there are tons of ways to make clothes that harvest energy. Imagine charging your phone just by walking or powering a fitness tracker with your knee bends. It's not science fiction - it's the future of fashion!
