Many current solutions require specialized materials or complex manufacturing processes, driving up production costs. This economic barrier limits the widespread adoption of EH systems, particularly in consumer electronics and large-scale industrial applications where cost is a critical factor.

Environmental factors and durability issues pose additional challenges for energy harvesting devices. Exposure to varying weather conditions, temperature fluctuations, and physical stress can degrade the performance and lifespan of EH systems over time. Developing robust, long-lasting solutions that can withstand diverse environmental conditions is essential for the practical implementation of energy harvesting technology in real-world scenarios.

Addressing these challenges requires innovative approaches and interdisciplinary collaboration. The exploration of novel materials, advanced energy conversion techniques, and intelligent power management systems are key areas of focus for overcoming the current limitations of energy harvesting technology.
