, a 2015 PhD graduate of the University of Sydney鈥檚听, created a world-first system, beating similar attempts conducted by US Navy researchers to design autonomous refuelling capability for drones. His system comprises a set of guidance, navigation and control algorithms, along with an infrared camera system, GPS and inertial sensors.

鈥淐ombined, they enable accurate and reliable relative positioning for autonomous airborne drone refuelling. Aircraft used in search and rescue missions, for example, could now remain airborne indefinitely as they would no longer be limited by the amount of fuel they can store on board,鈥� said Daniel.

PhD)听a postdoctoral research associate, 听at听听is the inventor of Trimph (Temperature-Responsive Injectable Modifiable Peptide Hydrogel), a revolutionary injectable biomaterial capable of aiding regeneration of damaged hard and soft body tissues such as cartilage, spinal cord and bones. Created as part of his PhD research at the University, Trimph is now an established start-up company.

鈥淭he injectable gel can also be used to stabilise dental implants. It reduces the need for open surgery. At room temperature, it can be injected into a desired location. When it heats to body temperature, it forms an elastic gel that adheres to the site without the need for physical containment,鈥� said Dr Fathi.

i,听who is the听听director at the University听has been recognised for her work on听new environmental friendly packaging that prolongs the shelf life of foods.

The professor said: 鈥淢ost food packaging today uses non-degradable polymers such as polyethylene. The existing biodegradable plastic, poly (propylene carbonate) (PPC)听contains metallic catalysts, which is a major obstacle to composting. But we have been extracting these impurities resulting in a 鈥済reener鈥� and more efficient method, and with the additional coating of the surface with a natural extract, creates antibacterial qualities.

, Laboratory for Sustainable Technology director in the was recognised for his leadership of听the Laing O鈥橰ourke鈥檚 centre of excellence in听strategic innovation.

The centre is a specialised听innovation lab designed to听promote positive change in听the construction industry and so far has invented, commercialised听and deployed innovations in听virtual and augmented reality,听construction-scale 3D printing, and听intelligent infrastructure.

鈥淥ne of the team鈥檚 inventions is a hardhat that measures your health in real time鈥� said Professor Harris.

听from the University鈥檚听听has created RIPPA鈩� (Robot for Intelligent Perception and Precision Application) and VIIPA鈩� (Variable Injection Intelligent Precision Applicator). Farmers no longer need to manually weed their farms thanks to the robot鈥檚 intelligence software that allows it to distinguish between crops and weeds.

鈥淭he innovation will dramatically improve land and labour productivity, allowing farmers to minimise labour costs and chemical inputs while maximising crop yield and quality, as well as improving information quality for better decision making, 鈥� stated Professor Sukkarieh.

Congratulating the five听, Deputy Vice-Chancellor (Research) said:

"We are delighted to have our researchers recognised in this list of the most innovative engineers in Australia. They are tackling complex problems in creative ways and inspiring others to bring new ideas to life. The University of Sydney has a proud tradition on innovation in engineering and it continues today."
