Abstract [en]

This thesis explores the viability of various energy harvesting technologies for powering micro-scale IoT devices in outdoor environments, specifically for products developed by Thule Sweden AB. Through a comprehensive literature review and experimental testing, we evaluated the performance of solar panels and piezoelectric systems to identify sustainable power solutions that could replace or reduce dependence on traditional battery power. Our methodology involved controlled laboratory tests and real-world applications on car roof boxes and bike trailers to assess the technologies under practical conditions. The experiments aimed to achieve a minimum daily energy output of 20 Joules. This target was chosen with reference to the energy consumption data of a specific IoT device used by Thule. The results demonstrated that while both solar and piezoelectric technologies have their possibilities and limitations, they hold promise for integration into IoT applications, offering a step towards more sustainable product designs. These findings contribute to a broader understanding of energy harvesting’s potential to reduce environmental impact and enhance the self-sufficiency of energy production in outdoor IoT applications.

Abstract [sv]

Denna avhandling undersöker genomförbarheten av olika teknologier för energiutvinning för att driva mikroskaliga IoT-enheter i utomhusmiljöer, specifikt för produkter utvecklade av Thule Sweden AB. Genom en omfattande litteraturöversikt och experimentella tester utvärderade vi prestandan hos solpaneler och piezoelektriska system i syfte att identifiera hållbara energilösningar som kunde ersätta eller minska beroendet av traditionella batterier. Vår metodik inkluderade både kontrollerade laboratorietester och praktiska tillämpningar på takboxar och cykelkärror för att bedöma teknologierna under praktiska förhållanden. Experimenten syftade till att uppnå en minsta daglig energiproduktion på 20 joule. Detta mål baseras på energiförbrukningsdata från en specifik IoT-enhet som används av Thule. Resultaten visade att även om både sol- och piezoelektriska teknologier har sina fördelar och begränsningar, har de potential för integration i IoT-applikationer, vilket erbjuder ett steg mot mer hållbara produktdesigner. Dessa fynd bidrar till en bredare förståelse för energiutvinningens potential att minska miljöpåverkan och förbättra självförsörjningen av energiproduktion för IoT-applikationer utomhus.
