Abstract

An energy harvesting device (2) is disclosed. The energy harvesting device (2) is configured to surround a portion of an electrical cable (4). The energy harvesting device (2) comprises a plurality of electrically separated and electrically conducting patch members (22, 22', 24, 24', 26, 26') configured to be arranged in such a manner that an electric potential difference (V) is provided between a first outlet point (B) and a second outlet point (A). The patch members (22, 22', 24, 24', 26, 26') are electrically connected to the first outlet point (B) and to the second outlet point (A). The patch members (22, 22', 24, 24', 26, 26') are configured to be attached non-invasively direct onto the electrical cable (4).

Description

technical field [0001] The present invention generally relates to an energy harvesting device for harvesting energy from an electrical cable. Background technique [0002] The use and number of distributed sensor systems has continued to grow recently, and the need to power the sensors and associated wireless communications has increased accordingly. [0003] A major challenge in these systems is to supply the required energy to these systems without the challenge of maintaining large numbers of batteries, often without sufficient space. A known solution to this challenge is energy harvesting, in which more or less continuously harvested ambient energy is supplied to the devices. [0004] Typical energy sources used in energy harvesting are light, vibration, or temperature differences. Unfortunately, in typical technical installations, these sources of energy are not present where the sensors are often installed. [0005] However, there is no shortage of cables (eg electr...
