This wearable multisports sensor from French company Piq is the most advanced I’ve found. It’s causing huge excitement in the sports world for its ability to detect and analyse – via a smartphone app – the subtlest variants in your tennis, golf and skiing performance.
The tennis-flavoured Piq (pictured) was designed in collaboration with racket-maker Babolat, and the sensor simply slips into the fabric wristband to give you information on your shot speed and stroke. Post-match, it will give you a detailed analysis of your performance – best serve, best rally – and an overall score. There are different accessories for golf and skiing (the latter an ankle strap) using the same sensor.
This slip of a sensor is quite amazing. It weighs just 9.8g and measures 44mm x 38mm x 5.4mm; it is waterproof (which suggests to me a swimming version may be in the works) and carries a digital display readable in bright sunlight. It has Bluetooth and NFC (Near Field Communication) for wireless connectivity, and the core technology is a 13-axis sensor. I didn’t even realise there were 13 axes. But when you consider that a skier, for example, has an intimate interest in his or her speed, duration, rotation, airtime, landing force, transition, carving angle, number of runs and turns, then yes, there are a lot of axes out there.
