Problems solved by technology

[0005] In summary, the linear stretch rate of the frictional nanogenerator in the prior art is up to 200%, and the surface stretch rate is up to 800%, which has the disadvantage that the stretch rate is still insufficient. Sensitivity of the sensor affects the application of triboelectric nanogenerator-based tactile sensors in multifunctional scenarios
