Taekwondo sensor socks
At the Beijing Olympics in 2008, Sarah Stevenson came within 20 minutes of being eliminated due to a judging error. In Taekwondo, two of the four-person judging panel must be in agreement for points to be scored; on this occasion, a crucial final blow was missed and Stevenson was eliminated. After viewing video footage the decision was overturned, but the experience undoubtedly knocked her off kilter for her final fight – which she lost.
This year, Taekwondo athletes will wear socks and clothing fitted with electronic sensors made by Spanish company Daedo. When contact is made, the sensors will register the blow, giving the judges a valuable back-up system. A companion video relay will help judges to quickly review footage to avoid mistakes in scoring.
Sensors have been tried before with mixed results, so care has been taken to refine the technology to Olympic standard for London 2012.
