• In the modern world of small-scale electronics, touch sensors unfold many numerous novel interaction techniques and other possibilities. Self-powered and flexible sensors are the future and this is where triboelectric nanogenerator-based touch sensors come. Here, surface engineering provided sufficient output performance such as 25 V, 0.4 mA/m2, and 16 mW/m2, for a Polydimethylsiloxane (PDMS) and Cellulose Acetate based TENG with micrometer separation distance. Additionally, the effect of surface modification is also quantified for better understanding. Moreover, the fabricated TENG device with micropatterned contact surfaces shows excellent tactile sensing capability of detecting and distinguishing forces of ∼0.05 N and exhibited a sensitivity of ∼3.67 V/N for small forces (<1 N). •TENG based self-powered touch sensor is fabricated using cellulose acetate nanofibers (CANF) and micro-patterned PDMS film.•The TENG showed an open-circuit voltage of 25 V, short circuit current density of 0.4 mA/m2 and power density of 16 mW/m2.•The TENG touch sensor was able to detect input forces of ∼0.05 N and the output linearly depends on the input force.•The sensitivity of the TENG touch sensor for small forces (<1 N) is 3.67 and 1.073 for forces between 1 and 10 N.
