Abstract: A capacitor sensor device for use in conjunction with a monitoring circuit system and call alarm system to perceive a patient movement employs a plurality of elongated electrical conductor devices positioned in horizontal parallel spaced relationship, an electrical insulating material forming an upper layer and lower layer over an about each electrical conductor device whereby the conductor devices are maintained in insulated parallel spaced relationship to each other, and a pair of electrical conductive connectors connected to alternate electrical conductor devices. The sensor device is constructed and arranged so as to be thin and flexible and formed in a selected configuration. In another embodiment, the capacitor sensor device can be used to activate a transmitter for a limited range paging system for a home application.
