Purdue University scientists have been inspired by nature to develop 3D light sensors for medical imaging. To do this, they used some of the architectural features of the web, thanks to which it is resistant to various loads.
The fractal structure of the web has inspired scientists to develop more robust light sensors. This can be useful for 3D imaging in medicine
The researchers argue that the web’s structure, which exhibits a repeating pattern, allows it to adapt to environmental conditions and not be damaged by winds.
“We used a unique fractal web design to develop flexible and reliable electronics that can easily interact with any three-dimensional curved surface,” said Chi Hwang Lee, assistant professor of biomedical engineering and mechanical engineering at Purdue.
Lee and his colleagues have created a domed photodetector system that can detect the intensity and direction of incident light. This matrix resembles the vision system of insects and crustaceans. The fractal structure of the spider web ensures a uniform distribution of external influences over the entire surface of the detector and better extensibility, so it can remain operational even with minor damage.
The results of their work are especially attractive for systems that require a large field of view and wide-angle images, the scientists say. This will be useful for medical and military 3D imaging.
