Speedo's new swimsuit, called the Fastskin LZR Racer, is grabbing attention at the Beijing Olympics. Two recently published US patent applications, US20080141431 and US20080141430, may reveal the technical secrets behind the innovative design that some say is responsible for the record-breaking performances of swimmers such as Michael Phelps of the US.
Inventors have been improving swimsuits for well over a hundred years, some less successful than others, as shown by this example from the 19th century. (US243834)
