Platysens” means Platypus + sense. Platypus is a semi-aquatic egg-laying mammal from Australia. In its bill, there are tiny electroreceptors and mechanoreceptors, which allows it to catch its prey under water, even when the water is murky. Inspired by the platypus, the company aims to use different senses to help athletics monitoring their movements.

Platysens has been part of the Incu-Tech Programme at the Hong Kong Science and Technology Park between 2014-2017. It is currently part of the Leading Enterprise Acceleration Program (LEAP) at the Hong Kong Science and Technology Park.


Marlin GPS Swim Meter

The Marlin GPS Swim Meter (or The Marlin) is a GPS Swim Meter that is designed to communicate with pool and open water swimmers. The Marlin combines GPS, motion sensors and voice technology to provide real-time audio feedback to swimmers. Important swimming parameters such as lap time, stroke rate and even navigation information are provided instantly to swimmers without disrupting the swimmer. The bone conduction headset allows for clear and crisp audio feedback underwater.
