The sensitive microphone recording could also be used in monitoring other aspects of sleep. Microphone to detect other sleep disturbances HappyWakeUp® is available for Nokia smart phones based on S60 3rd ed FP1 platform at. "In case of sleep-associated diseases and symptoms you should contact your doctor", says Salmi. HappyWakeUp is not a medical product or treatment to any disease. Elevated stress-levels are associated with several risk factors and even diseases, such as hypertension and problems with the heart and brain. "Pleasant mornings help avoid stress in your body and brain. The continuous use of the clock helps the internal clock in your brain learn the proper sleep rhythms. After a trial period of some days or a week, you start to notice the benefits", promises Salmi. "The alarm signal during deep sleep is stressful and familiar to everyone, but with the smart alarm clock this is avoided. If the subject is sleeping calmly, no alarm signal is given before the ultimate alarm time. During the last 20 minutes before the ultimate alarm time, the analysis is activated to give a soft alarm signal, if there are movements indicating that the sleeping subject is awake or "almost awake". The appropriate almost-awake moments are detected by using a microphone and statistical analysis of voices. The mobile phone is located beneath the pillow or the bed linen or near the sleeping subject. The alarm time is set normally with the mobile phone. During these moments, the body and brain are already awake and waking up is natural and easy "It is rather an arousal clock than an alarm clock", says Salmi. The smart alarm clock gives an alarm signal in the morning just before the ultimate alarm time, if the sleeping subject is awake or "almost awake" due to the natural sleep rhythms. Everyone has heard the typical voices, when a mobile phone has accidentally called you from someone's pocket", says sleep specialist Tapani Salmi, MD, PhD.īased on the new technology, the sleep research group developed the smart alarm clock for mobile phones called HappyWakeUp. "Very soon we noticed that a common microphone is very sensitive to any sounds and voices produced by movements in the bed during night-time. In Tampere University of Technology MSc Väinö Virtanen started to record and analyse snoring two years ago to develop a simple screening method. It is the first health-promoting mobile phone application in the world. The first application of the new technology, a smart alarm clock for mobile phones, HappyWakeUp®, is now available. Research conducted in two Finnish universities, Tampere University of Technology and the University of Helsinki, resulted in the development of a brand-new technology for screening and even diagnosing sleep disorders.
