Abstract

A tactile sensor, constructed on an airlaid paper substrate and coated with a composite of graphene/PEG-TiAlC, is introduced. Leveraging the unique properties of papers, the sensors are folded into two origami configurations, enhancing sensing capabilities by amplifying Electrical Contact Resistance (ECR) under external forces. Sensitivity and response evaluation are executed. The sensor's practical utility is exemplified through its adeptness in differentiating muscle movements, particularly in the lumbar area and the metacarpophalangeal joint of the index finger.
