A self‐powered pressure‐sensor matrix based on ZnS:Mn particles for more‐secure signature collection is presented, by recording both handwritten signatures and the pressure applied by the signees. This large‐area, flexible sensor matrix can map 2D pressure distributions in situ, either statically or dynamically, and the piezophotonic effect is proposed to initiate the mechanoluminescence process once a dynamic mechanical strain is applied.
