Abstract Wearable sensors that measure parameters associated with physical activity and bodily motions have been regarded as an indispensable tool for assessing personal wellness. Recent advances in nanocomposite strain successfully used monitoring skin strains other strain‐derived physiological parameters. This study complements the existing body of work presents a flexible, self‐adhering, fabric‐based wearable sensor measuring human motions. Graphene nanosheet thin films are directly spray‐coated onto kinesiology tape (K‐Tape) to obtain self‐adhering high sensitivity linearity. Their stable sensing performance repeatability verified, while subject tests confirm they adequately capture muscle engagement during functional movements. In addition, densely distributed can be achieved using electrical impedance tomography measurement approach algorithm. Spatial is demonstrated single strip piezoresistive K‐Tape, well when K‐Tape network or mesh pattern formed. The results show promise graphene meshes how specific major groups engage different activities.
