A micromechanical memory sensor. The sensor comprises a latch member mechanically latching upon detection of a threshold value of a variable condition and circuitry for detecting such latching. A sensor further includes a resetting mechanism for electrically unlatching the latch member whereby the sensor latched purely mechanically is electrically reset for repeat use.

[ Having thus described the invention, we claim:] [1.] A micromechanical sensor comprising:a mechanical latch being latched upon detection of a threshold value of a variable temperature condition, latching occurring by movement of components of the latch induced by the variable temperature condition

[ Having thus described the invention, we claim:] [1.] A micromechanical sensor comprising:a mechanical latch being latched upon detection of a threshold value of a variable temperature condition, latching occurring by movement of components of the latch induced by the variable temperature condition;a readout mechanism operatively connected to the latch for detecting whether the latch is latched; anda resetting mechanism operatively connected to the latch electrically unlatching the latch by inducing movement of the components electrically whereby the sensor latched purely mechanically is electrically reset for repeat use. [2.] A micromechanical memory sensor comprising:a latch member having a sensing mechanism and a resetting mechanism mechanically latching upon detection of a predetermined temperature extreme;a readout mechanism operatively connected to the latch member for detecting whether the latch member is latched, and,a mechanism operatively connected to the latch member for electrically resetting the latch member.
