2. About Energy Harvesting Introduction
3. Used batteries or discharged accumulators Powered by EPAM
4. Self-winding watch Powered by EPAM
5. Solar-powered calculator Powered by EPAM
6. Using Energy Harvesting Solutions
7. What is this? Powered by EPAM
8. What is energy harvesting? Powered by EPAM Crystal radio - a simple radio receiver It uses only the power of the received radio signal to produce sound, needing no external power. It is named for its most important component, a crystal detector, originally made from a piece of crystalline mineral such as galena. This component is now called a diode.
9. RF RF energy is currently being broadcasted from billions of radio transmitters around the world, including mobile telephones, handheld radios, mobile base stations, and television/radio broadcasting stations. • TV/FM station • GSM base station • WiFi (PoWiFi) • Etc. Powered by EPAM = ∙( 4 ∙ ∙ )2 Friis equation Soviet Union broadcast station – 12..500kW Belarus DVT-T TV station – 24.6kW
10. Received power: TV, WiFi Powered by EPAM BLE 3x ADV needs 3.2 uWs
11. Thermal The Peltier effect is the presence of heating or cooling at an electrified junction of two different conductors and is named after the French physicist Jean Charles Athanase Peltier who discovered it in 1834. Изображение Powered by EPAM
12. Vibration Harvesting kinetic energy from vibrations, even at the lowest levels of the acceleration and frequency range – environments that are often found in industrial environments. 25-80Hz Изображение Powered by EPAM
13. Soil Microbial fuel cell (MFC) is a bio-electrochemical system that drives an electric current by using bacteria and mimicking bacterial interactions found in nature. Изображение Powered by EPAM MudWatt

18. Heat Pump A heat pump is a device that transfers heat energy from a source of heat to what is called a heat sink. Heat pumps move thermal energy in the opposite direction of spontaneous heat transfer by absorbing heat from a cold space and releasing it into a warmer one. A heat pump uses a small amount of external power to accomplish the work of transferring energy from the heat source to the heat sink. Изображение Powered by EPAM • Soil-Water • Air-Air
