A housing can have two superposed housing members and a joint member connecting lips of the housing members to one another along at least a portion of a periphery. The housing members and the joint member can all be made of an elastomeric material, and thus be flexible, compressible, and have elasticity. An electronic unit within an air-filled cavity between the housing members can be received on a board, itself being received on one of the housing members, and having a press-switch unit covered by the other one of the housing members and forming part of a press-switch system.

A body worn patient monitoring device includes a flexible substrate having a plurality of electrical connections adapted to be coupled to a skin surface to measure physiological signals. The flexible substrate is adapted to be directly and non-permanently affixed to a skin surface of a patient and configured for single patient use. A communication-computation module, removably attached to an upper surface of the flexible substrate, is configured to receive physiological signals from the flexible substrate and includes a microprocessor that is configured to process and analyze the physiological signals. A series of resistive traces screened onto the flexible substrate are configured as at least one series current-limiting resistor to protect the communication-computation module.

Systems and apparatus for monitoring physiological electrical activity of an individual include a first electrode unit for receiving a first signal indicative of electrical activity at a first location on a body of the individual and a second electrode unit for receiving a second signal indicative of electrical activity at a second location on the body of the individual.
