Sony's 'Smart' Tennis Sensor
Sony showed off a prototype tennis racket sensor earlier this year that promised to track useful data about your technique and transmit it to your smartphone. In a week where sports-tech is all the rage, that prototype has turned into reality with the 'Smart Tennis Sensor' set to hit store shelves early next year.
The Smart Tennis Sensor weighs eight grams, measures 17.6mm tall, and is 31.3mm in diameter, meaning that it shouldn't add much bulk to your racket and measures the speed of your swing, the speed of the ball, where the ball makes contact with the racket, and what kind of stroke you're playing, all of which can be viewed in time with video footage recorded through the app.
There's no word on a release outside of Japan for now.
