Nature has spent 3.8 billion years refining form, function and process. With scientific rigour and creativity, we can use nature to solve almost any problem – from the nanoscale to the global. We call this bioinspiration.

Watch: Design inspired by nature

Advanced materials. Chemical sensors. Acoustic spaces. Solar cells. All can be improved by taking design principles from animal and plant systems.

BioInspiration – it's technology inspired by nature.

Bioinspiration at the University of Melbourne

About

Bioinspiration involves taking principles from biological systems and applying them to technological and design problems. As global challenges become more complex, we’re increasingly drawing inspiration from biological systems to find new solutions.

The BioInspiration Hallmark Research Initiative exists to enhance innovation and impact by enabling convergence between the biological and physical sciences, engineering and design. This requires collaboration between practitioners in diverse fields including physics, chemistry, materials science, engineering, design, architecture, evolutionary biology and ecology.

The initiative works with a range of research institutes and industry partners to find bioinspired solutions to a broad range of problems in:

  • nano-optics and materials
  • chemical sensors
  • design in architecture.

Our research capability

The initiative brings together researchers from across the University, including:

  • Faculty of Science (BioSciences, Chemistry and Physics)
  • Melbourne School of Engineering
  • Faculty of Architecture, Building and Planning.

The initiative has links to the material science research community, including the University’s Materials Characterisation and Fabrication Platform. This combination of infrastructure and expertise can enable rapid materials development—and help commercialise research.

The ARC Centre of Excellence in Exciton Science is also connected with the initiative. This means associated researchers and partners can access extensive infrastructure for the creation and testing of new materials and devices.

Get involved

The initiative supports a range of activities that enable research and innovation, including workshops, public events and a seed-funding scheme.

In 2019, the initiative funded several research projects that are in progress. Further project funding will be available in 2020. If you’re a University of Melbourne researcher or staff member, see Funding for more information.

Research themes

Bioinspired research is rooted in observations of nature as a source of inspiration. This can be applied to any area of innovation, including the development of:

  • new materials
  • devices
  • technology
  • structures and processes.

The initiative has identified three key research themes that leverage existing research strengths.

Bioinspired design in architecture

The search for optimal structural forms, materials and designs inspired by nature originates in the early 20th century. Examples of bioinspired materials, structures and surfaces include:

  • biomimetic self-repairing structural materials
  • bioinspired adaptive adhesion systems
  • an adaptive biomimetic facade shading system, Flecton.

Bioinspiration is also an emerging area of research associated with design thinking by analogy in architecture, engineering and industrial design.

Bioinspired nano-optics and materials

Biological structures are increasingly the source of inspiration to solve complex challenges. For example, in photonics and materials science.

Natural structures such as beetle cuticles and butterfly wing scales have inspired the development of materials including:

  • anti-reflection coatings to improve the efficiency of solar cells
  • anti-counterfeiting technologies (such as metallic holograms on credit cards and banknotes)
  • optical devices that focus or polarise light.

Projects

Our seed funding scheme exists to encourage innovation. In 2019, there were 10 applicant groups. The top three submissions received A$10 000 each. These projects are currently in progress.

In 2020 we funded an additional four projects.

The initiative encourages external organisations to get involved in these projects.

Flat top white mushrooms with long stalks grow in red soil

Develop a sustainable building material – using mushrooms

Cladding is used to protect and insulate buildings. Usually, cladding ‘sandwich’ panels are made with aluminium and synthetic materials. This makes them cheap, light and easy to install. But it also means they leave a large carbon footprint.

Mycelium, on the other hand, has the required properties for sandwich panels while being biodegradable. It is porous, hard and lightweight and can be produced in a way that is environmentally sustainable. And it is easy to grow in any size and shape. Mycelium is the network of fibres from which mushrooms flower.

At present, mycelium has been commercialised for use in packaging and for interior building linings and fittings. But it has not been developed into a viable composite system for use in exterior environments. This project will explore the following:

  • Can we harness the power of mycelium to devise more sustainable technology for our house cladding?
  • Can this technology innovation inspire more sustainable circular economy models in the building industry?

Super-iridescent, strong and beautiful materials inspired by the most successful animal on earth: beetles

Excluding bacteria, almost one-quarter of all living creatures are beetles. They are quite simply the most successful group of animals on the planet. A key contributor to this success is the strong exoskeleton including the shell that protects the beetles’ wings. These shells are also visually striking because they use nanostructured films to manipulate light in diverse ways.

Films with a similar appearance are produced using advanced industrial processes. They’re widely used in a broad range of coatings, security features and sensors. This project aims to understand the optical properties of microscopic twisted features in the shell of scarab beetles. We will also uncover the complex light-matter interactions influencing the appearance of the beetle shell.

The ultimate goal is to create super-iridescent coatings that can be produced using industrially scalable and environmentally sustainable methods – inspired by beetles.

A holistic framework for developing futuristic bioinspired cellular structures for blast protection

We are developing the world’s first protective bioinspired cellular structure.

Protective structures are needed to keep people, buildings, vehicles and infrastructure safe from explosive and blast damage. Currently, many engineered cellular structures are being investigated for protective applications. But their small set of design parameters produce simple structures with limited performance.

Using solutions from nature – such a bone structure – we will develop protective structures that perform better than existing products. This will produce real-world benefits for the building and defence industries.

Bioinspired bactericidal ‘nano-knife’ coatings for orthopaedic implants

We are developing coatings for prosthetic joints to protect against common bacterial infections.

Joint replacement surgery helps to improve the quality of life for millions of people around the world each year. Yet around 2 per cent of patients experience complications as a result of bacterial infection during surgery. Bacteria can form biofilms on the surfaces of a prosthetic joint, which shields them from antibiotics.

But nature has developed another way to kill bacteria – using knife-like nanostructures called chitin nanopillar arrays. These nanostructures are found on cicada and dragonfly wings. They evolved as waterproofing and anti-fouling agents and can mechanically rupture and kill bacterial cells.

Inspired by the size, shape and arrangement of these nanostructure arrays, we will optimise the coatings of prosthetic joints to protect against common bacterial pathogens. We will also design ways to add the coatings to prosthetic joints before surgery. This will provide a chemical-free way to prevent infection at the implant site.

A forest of green bamboo

Bamboo-inspired production of 3D-printed hierarchical porous bio-ceramic tissue scaffolds

We are developing a scaffold for bone tissue engineering that takes inspiration from bamboo.

Surgeons treating bone tissue defects use these scaffolds to encourage the growth of new bone. To work properly, tissue scaffolds need to have particular biological and mechanical properties. For example, they have to interact with living tissue without triggering the immune system to attack. They need to be porous yet strong. And they have to be biodegradable.

Bamboo has a high stiffness-to-density ratio. Using bioresorbable and bioactive ceramics, the team will produce a scaffold that mimics the microstructure of bamboo. We will also investigate the relationships between formulation, processing, structure, and performance.

Our aim is to produce an easily manufactured 3D-printed tissue scaffold that mimics the microstructure of bamboo.

Squid-inspired lighting: the functional bio-bulb

We are creating the world’s first “functional bio-bulb” – a light that works using bioluminescence.

Bioluminescence – the production of light by a living organism – has inspired human imagination since ancient times. The Kombumerri people of south-east Queensland believe that bioluminescent fungi are the spirits of their ancestors. Ancient Greeks were captivated by the “cold light” of the sea, which was produced by marine creatures.

Bioluminescence has attracted significant interest as a light source. It is efficient, has low environmental impact, and produces soft light in unique colours. But developing a working light using bioluminescence faces some challenges.

They include:

  • developing a way to switch the light on and off
  • dealing with waste produced by the bioluminescent organism
  • modulating the intensity of the light.

Using mathematical models, synthetic biology and design, we will create the world’s first “functional bio-bulb”.
