that of light and vibrations, offers sustainable alternatives. Technologies, alongside ambient radiation, temperature gradients, light, kinetics, motion and vibrations, are renewable energy sources for active RFID tags, promising extended operational lifespan and decreased maintenance expenditures.


Propelling the growth of the energy-harvesting market Te light harvesting systems market is expected to see the highest CAGR and market share during the forecast period to 2028; see Figure 4. Governments worldwide are introducing policies and offering incentives to boost the adoption of renewable energy, and particularly light harvesting. For example, the US government provides a federal Investment Tax Credit for solar energy systems, encouraging the use of photovoltaic cells. Similarly, Germany’s feed-in tariff system guarantees payments for renewable electricity, driving the installation of solar panels and thus promoting this sector’s expansion. Tese measures, along with tax credits and feed-in tariffs, encourage investment and innovation, propelling the growth of the light harvesting market in the forecast period. By application, the building and home automation sector held


the largest share in 2023, driven by the growing demand for energy-efficient and smart-living applications. Te integration of energy-harvesting systems into these systems is a significant growth factor, providing sustainability, convenience and cost savings. In addition to providing energy efficiency and sustainability, with wireless connectivity and scaleability, these systems offer easy integration without complex wiring. Also, their maintenance-free operation and reduced environmental impact further contribute to their growth in building and home automation applications. During the forecast period, North America is anticipated


to dominate the energy-harvesting systems market, driven by a growing focus on renewable energy and sustainability. Governments and regulatory bodies are implementing policies and incentives to encourage the adoption of clean energy
