Salt for Energy Harvesting and Sensor Applications

LITERATURE REVIEW

This study examined a hybrid solar energy receiver designed with
sunflower-inspired geometry. The system integrates photovoltaic
panels with thermal energy collectors to maximise overall
efficiency. The research highlighted on how biomimetic solar
tracking, combined with advanced energy absorption
technologies, can significantly improve energy generation while
promoting environmental sustainability. Researchers developed a
system for utilising solar power system, which mimics the
phototropic behaviour of sunflowers. Unlike conventional
tracking mechanisms, this system autonomously adjusts its
orientation based on sunlight intensity without requiring external
power sources. Performance testing revealed that the SunBOT
captured approximately 90% of available sunlight, compared to
only 24% captured by traditional static solar panel configurations.

This breakthrough technology shows considerable promise for
widespread solar power applications in both rural and urban
environments (He & Chen, 2023). These researchers focused on
enhancing solar system efficiency through biomimetic principles
derived from sunflower movement patterns. They developed an
advanced solar tracking system capable of replicating the natural
heliotropic behaviour of sunflowers to optimise panel positioning
throughout the day. The system employs strategically positioned
light-dependent resistors (LDR sensors), coupled with
microcontroller-based precision adjustments. This configuration
demonstrated substantial improvements in energy capture
compared to conventional static installations. The technology
shows versatility across residential, industrial, and commercial
applications, with customisable features for specific
environmental requirements.

Results indicated energy efficiency improvements of 18 to
25% over standard systems, establishing it as a viable solution for
enhanced solar energy generation in both urban and rural settings
(Alnaieli, Jadallah & Numan, 2024). Another study examined a
dual-axis sun tracking system integrated into a smart flower
design.
