Technology in the bedroom can be a real no-no. As well as interfering with romance as your other half engages in late-night Facebook and Twitter updates or a final session of Angry Birds, it’s less than conducive to relaxation thanks to the temptation to check breaking news stories or even work email.

Speaker maker gear4 think it’s hit on a way to use technology in a more relaxing fashion: its Renew SleepClock will be able to monitor how much of your sleep is fitful, restless sleep and how much is rejuvenating deep sleep.

A pair of sensors hidden behind the company logo on the gear4 iPod speaker dock will unobtrusively monitor the user’s breathing and movements. Over a period of time it will build up a picture of their sleep patterns and suggest the optimal time frame for waking up. Waking up rested and rejuvenated involves doing so at the right point in the sleep cycle, as well as getting enough of the right sort of sleep in the first place, explained gear4.

The sensor in the Renew SleepClock extends 1.5m – enough to cover the distance from a bedside table and half a double bed. It is able to recognise movement through bedclothes and duvets and if your partner throws their arm around you in the middle of the night.

Pricing and an exact launch date for the gear4 Renew SleepClock has yet to be announced, but the company was showing a working sample at IFA. The speaker dock and sleep monitor will work with iPods, iPhones and iPads.
