When a worker S unintentionally walks in a swing range Ra of the robot arm 14 and contacts the emergency stop pressure sensor 17, a detection signal is transmitted to a control unit 19, and the control unit 19 shuts power transmission to a driving source swinging the robot arm. The emergency stop pressure sensor 17 has a first electrode and a second electrode constituting a pair of electrodes and an intermediate layer formed of rubber or a rubber composition, which is disposed between the pair of electrodes, the intermediate layer generating power upon deformation caused by contact with a contacted body (the worker). A side of the intermediate layer in a laminate direction undergoes surface modification treatment and/or inactivation treatment. With this treatment, the one side and the other side of the intermediate layer have different degrees of deformation to the same deformation adding force."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Emergency stop pressure sensor, safety device, and safety system","description":"Emergency stop pressure sensors 17 are installed on both side surfaces of a movable link 11 of a robot arm 14 of an assembly robot.
