1. A lifetime indicator system, comprising:
a plurality of different monitor devices configured to monitor different types of wear-out stresses in parallel, wherein one of the monitor devices is a first wear-out monitor device configured to record a wear-out stress without being powered;
a plurality of analog to digital converters (ADCs) electrically connected to respective ones of the monitor devices for receiving monitoring signals therefrom and configured to generate an output;
a memory device having stored therein a predetermined alert limit for each of the different types of wear-out stresses; and
a microprocessor connected to the ADCs and the memory device, the microprocessor configured to receive the output from each of the ADCs and to determine whether the predetermined alert limit has been reached for one or more of the different types of wear-out stresses based on the output.
