Sensor, sensor system and method for producing a sensor

Abstract

The invention relates to a sensor comprising a thermoelectric generator (10) for converting thermal energy into electric energy, a thermally active upper and lower side (10a, 10b), contact areas (14, 16) for contacting a source of heat and a source of cold, and thermal conductor paths (18, 20) which connect the contact areas (14, 16) to the upper and lower sides (10a, 10b) of the thermoelectric generator (10) for generating a thermal gradient between the upper and the lower sides (10a, 10b) of said thermoelectric generator (10), wherein the first and / or the second conductor path (18, 20) are designed to reverse the thermal gradient in the sensor when at least one of the contact areas (14, 16) is oriented differently relative to at least one of the upper side and lower side (10a, 10b) of the thermoelectric generator (10). The invention further concerns a corresponding method for producing a sensor and a sensor system.

Description

technical field [0001] The invention relates to a sensor, a sensor system and a method for producing a sensor. Background technique [0002] The Internet of Things is called one of the most important future developments in the field of information technology. The Internet of Things is understood to mean that not only people have access to the Internet and are networked via it, but devices are also networked with each other via the Internet. The field of the Internet of Things concerns, for example, manufacturing and home automation (Hausautomatisierung) for temperature measurement. Sensors are already available, but have high manufacturing costs. Furthermore, efforts have passed to develop sensors that simultaneously obtain the necessary electrical energy from the environment. This is made possible by photovoltaic cells as well as by thermoelectric generators that harvest energy from temperature differences. [0003] The obtained energy of the thermoelectric generator is...
