“There are always new improvements being introduced into sport,” says Dr Claire Davis, Senior Lecturer at the University of Birmingham. “While most changes are incremental in nature, major step changes in performance and safety have occurred when new materials are introduced. For example the pole used in pole vaulting has changed from solid wood to bamboo to aluminium and now glass or carbon fibre composite materials constitute the poles of choice.”
“Some of the latest materials developments, include so called ‘smart materials’, such as piezoelectric ceramics. These develop an electric voltage when stressed and can be used in active damping systems for skiers and tennis players, with the aim of minimising injuries and improving performance.”
Dr Davis will make her comments as part of the BA Isambard Kingdom Brunel Award Lecture – ‘The role of materials technology in sporting performance’, an event at the BA Festival of Science. The Festival is taking place in Norwich from 2-9 September and will bring together over 300 of the UK’s top scientists and engineers to discuss the latest scientific developments with the public.
Dr Davis will investigate the influence of equipment design and raw materials on various aspects of sporting performance and discuss the ‘technology gap’ that has arisen between developed and developing nations. She will also highlight the potential for British sporting success at the 2008 and 2012 Olympics in the technology-driven sports at which the nation has traditionally excelled (for example: cycling, sailing and rowing).
Dr Davis will also consider technological developments in cycling, golf and tennis, where the changing materials and design of rackets has increased the speed and power of serves but caused audience dissatisfaction by reducing the length of rallys at tournaments played on fast surfaces, such as grass at Wimbledon.
The opportunity to present a popular and prestigious BA award lecture at the Festival of Science is offered to five outstanding communicators each year. The award lectures aim to promote open and informed discussion on issues involving science and actively encourage young scientists to explore the social aspects of their research, providing them with reward and recognition for doing so.
In addition to lectures and debates at the University of East Anglia, the Festival will also feature a host of events throughout Norwich as part of the Science in the City programme.
This year’s Festival is supported by the University of East Anglia, the East of England Development Agency and Microsoft Research. The Press Centre is sponsored by AstraZeneca.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
