Description

1. Technical field

[0001] The invention relates to an ultra-flat, electromagnetic power generation system specifically designed for the human body. This system generates electrical energy through linear relative motion between a magnetic element and a coil element, without requiring an external power supply. This energy is stored in a flat, rechargeable battery with integrated charging electronics and powers all mobile devices. Energy generation occurs through movement, including movements from human body parts (e.g., arms, legs, feet), manual, technical, or mechanical motion, as well as movements from devices and objects. The device is minimal in size, approximately 2 mm thin, and fits easily into any pocket.For this purpose, the aforementioned elements can be integrated into textiles and other possible materials and attached to objects using flexible fastening options such as adhesive, adhesive film, ties, hooks, etc., to suitcases, bags, backpacks or to clothing, shoes or human body parts such as arms, legs, feet, etc. 2. State of the art:

[0002] Current generators are mostly rotary and unsuitable for flat, mobile applications. The increasing demand for compact, off-grid power sources for mobile electronics necessitates new solutions for decentralized power generation. Conventional power generators are based on rotating components, which are unsuitable for flat, compact applications. At the same time, the need for mobile, space-saving power sources that operate independently of grid power is growing. Existing energy harvesting technologies (e.g., solar, thermal, piezoelectric) are either low-performance or highly dependent on environmental conditions. The present invention offers a self-sufficient, novel, flat-integrated power generation system that generates energy through simple, unobtrusive movements and stores it directly in an ultra-thin battery. 3. Object of the invention:

[0003] Provision of a flat, mechanically simple power generation system that generates electrical energy through linear motion and stores it in a flat battery, has minimal size and is suitable for all mobile electronic devices. 4. Summary of the invention

[0004] The invention comprises the following elements: 1. An ultra-flat, linear induction generator specifically designed for the human body as an electromagnetic power generation system, which moves laterally (linearly) over a coil element, generating and storing electrical energy through linear relative motion between a magnetic element and a coil element. 2. An ultra-flat coil element specifically designed for the human body, which is designed as a flat conductor structure and experiences a changing magnetic field through the movement of the magnet, thereby inducing current. 3. An ultra-flat linear induction generator system and integrated battery system with charging electronics, specifically designed for the human body, which stores the generated power and includes induction (wireless) and USB-C or similar connection, and functions as a self-sufficient mobile power supply system for mobile devices.

[0005] The generated electrical energy is stored in a flat battery via integrated electronics (rectifier, voltage regulator). The entire unit is designed for flexible mounting options, allowing it to be used as an external, self-contained charging pad, power bank, generator, and energy supply system in mobile devices, housings, textiles, clothing, the human body, and all movable objects. 4.
