A new wetsuit for surfers and swimmers will help prevent shark attacks by making the wearer invisible and seemingly less tasty to sharks. The will be two wetsuit styles that will help deter attacks in two different ways. One, designed for swimmers and divers, will use a Cryptic Pattern that will cause the wearer to blend into the background, making them difficult for sharks to see. The other, for surfers, will feature a Warning Pattern that will mimic the patterns of untasty fish,...

Designed for swimmers, the device will attach to a set of goggles to let athletes check their heartbeat without breaking stride. The device will attach to one side of the goggles, where an optical sensor will measure the heart rate from the temporal artery. As an onboard microprocessor will track the heart rate in real time, color-coded LEDs will illuminate to let the user know if they are currently on their chosen heart rate (Fat Burning, Fitness or Maximum Performance). The...

The new super-snorkel will allow swimmers to swim and breathe more easily without ever lifting their face from the water. The snorkel will be designed to fit around the head, allowing the user to take in air from the top valve while exhaling it through the mouth. The system will be arranged so that no spent air will remain in the device and no water will enter, and it will fit tightly around the head to stay securely in place without drooping.

New inflatable floatation device will be about the size of a mobile phone, and will be quickly inflated to provide support to exhausted swimmers. The device will be small enough to be strapped to the waist or gear. Pulling the trigger will cause the canister of compressed air to fill the tube, which will be bright yellow to make spotting by rescuers easier. The device will be attached to the user by a tether, and can be deflated and reused.

Inspired by the life vests used on airplanes, I suggest creating the world's first inflatable wetsuit. The wetsuit will inflate when the wearer pulls a cord that will cause a CO2 cartridge to inflate an air bladder located on the back of the suit.

I'm really fond of the idea of creating a device that helps strengthen the connection between a swimmer's arms and legs, effectively making both of them more powerful. Worn in front of the body, it can be used to generate resistance so the wearer uses more muscle power with each stroke. Worn running down the spine, it helps maintain correct posture.
