Leading health monitor manufacturer Tanita today announced [JP] a sensor-equipped mat that’s supposed to measure the deepness and quality of your sleep. The company, which is also active in the US, says placing the mat under your mattress is enough. The system will then keep track of your body motion, breath rate and pulse throughout the night.

All data from the so-called Sleep Scan system is stored on an SD or SDHC card and can be analyzed through a piece of software Tanita is bundling with the “hardware”. You can then evaluate the quality of your sleep (how long you really slept, how often you woke up during the night etc.) through graphs and a “sleep score” the software gives you, based on information coming from the capacitor microphone inside the mat that tracks vibrations.

The mat is sized at 863×314×26mm and weighs 1.3kg. A 2GB SD card is enough to store the data of about 500 sleep cycles.

Tanita plans to start selling the Sleep Scan in Japan from May (price: $395). As mentioned above, the company is active outside Japan but hasn’t said yet if the Sleep Scan will find its way to international markets as well.
