Abstract

See full text

An electronic system for monitoring a physical parameter includes an ADM comprising an accumulation mode sensor for measuring the physical parameter by generating electrical energy associated with the physical parameter in response to a surrounding condition, and an energy storing device coupled to the accumulation mode sensor for accumulatively storing the generated electrical energy; a power source; and an SoC coupling with the ADM and the power source, configured such that the stored electrical energy is monitored, and when the stored electrical energy is equal to or greater than a pre-defined threshold, a wake-up event is generated to trigger the SoC to operates in a run mode in which the physical parameter is wirelessly transmitted to a receiver and the stored electrical energy in the energy storing device is discharged, and then the SoC returns to a sleep mode in which a minimal power is consumed.
