Researchers say their SunBOTs are 400 percent more efficient than comparable stationary devices.
However, this problem has now been overcome. The team has developed a polymer that is responsive to being simulated by light. The system, which they have named sunflower-like biomimetic omnidirectional tracker—or SunBOT for short—is able to instantly detect and track a light source autonomously. It can do this across a range of temperatures without power supply or any human intervention.
The researchers tested their artificial sunflowers to see how efficient they were at harvesting solar energy. Findings showed they were up to 400 percent more effective than non-phototrophic materials.
