Abstract

The invention relates to a device for reporting events. The device has a chemical energy store (104) which releases thermal energy upon contact with moisture. Furthermore, the device has a converter (106) which is designed so as to convert the thermal energy into electrical energy, and a circuit (108) which is designed to generate an electric signal to report the event when operated by the electrical energy.

Description

technical field [0001] The invention relates to a device for reporting an event, a method for reporting an event, a monitoring system and the use of a chemical energy store which can be used in particular in conjunction with a microsystem. Background technique [0002] Various automated microsystems have been developed. Here, however, the problem of a sufficient energy supply arises, for which a battery or a combination of an energy harvester and a backup battery is used. When using only batteries, the service life of the microsystem is limited. When using energy harvesters, it is basically impossible to guarantee the functionality of the microsystem at a certain moment, because it is not known in advance whether the energy harvester has already obtained enough energy from the environment. The energy harvester is in the form of any energy harvester that harvests energy from the environment. Contents of the invention [0003] Against this background, the use according to...
