Patent ID: 7692914

Claim:
A microsystem, comprising: at least one sensor and/or actuator, a signal processor and/or control mechanism linked therewith, a timer, and an electrical energy storage unit as a current source for at least the signal processor and/or control mechanism, wherein the signal processor and/or control mechanism has a mode switching mechanism by means of which it can be set to an operating mode and to a resting mode with reduced current consumption compared with the operating mode, and wherein the mode switching mechanism has at least one control signal input which is electrically connected with the timer for applying a mode switching signal, characterized in that the timer is a mechanical timer which has at least one micromechanical cantilever which is coupled with at least one electrical element electrically connected to the at least one control signal input of the signal processor and/or control mechanism in such a way that said electrical element is time-dependently set, wherein the cantilever comprises an energy store of the timer that is operative for delaying the cantilever's return to a resting position from a contact position.
