This paper reports the development of a wrist-watch type wearable system for mental stress evaluation. A pulse sensor has been developed using the PVDF film for heart beat intervals detection. Visualization of mental stress using a modified Symmetrized Dot Patterns (SDP) method has been proposed. The system is testified through mental stress experiments.
