The practice of analyzing the functions and mechanisms inherent in living organisms and applying them to manufacturing is known as “biomimetics” or “biomimicry.” Over various epochs, biomimicry has emerged as a source of innovations and technological breakthroughs.
Amid the global climate change crisis and ongoing efforts to promote efficient material use and recycling, there's growing anticipation that biomimicry could play a crucial role in realizing a circular society and mitigating environmental impacts. Let's delve into the current landscape.
Achieving the Ideal
"In simple terms, biomimetics involves harnessing the optimal features of systems that have evolved over billions of years within natural cycles on the Earth," explains Kazuhiko Ishihara, Specially Appointed Professor at Osaka University's Graduate School of Engineering.
For three decades, Professor Ishihara has dedicated his research to developing the MPC polymer, a material that mimics the structure of the human cell membrane. This polymer boasts exceptional hydrophilic and water-retaining properties, coupled with the ability to prevent the adhesion of substances like proteins. In the summer of 2023, Alcon Japan introduced a contact lens using MPC polymer that mimics the human cornea.
