A new wave of innovation in sleep assistive technology

The significance of slow wave activity (SWA)

the significance of slow wave activity

Slow wave activity (SWA) during sleep has beneficial effects on the restoration of cognitive function during the day. 

It has been shown that memory consolidation and learning capacity during waking hours are positively influenced by achieving slow wave sleep at night.


Research findings:

 

  • The length and the strength of slow waves matter
  • Intervention during slow wave sleep can enhance slow wave activity
  • Acoustic stimulation found to be an effective way to increase SWA

Acoustic stimulation found to be effective at increasing slow wave activity

Once investigated, acoustic stimulation, or sound, was found to be an effective way to enhance slow waves. 

Additionally, waves enhanced by sound were similar to those spontaneously generated slow waves observed during natural sleep††.

SmartSleep: Setting the tone for the future of sleep

Setting the tone for the future of sleep

Philips has developed a closed-loop, EEG-based wearable system (SmartSleep) that uses highly sensitive sensors to detect deep sleep in real time.

The system uses auditory stimulation to enhance slow wave sleep without causing arousals.

 

SmartSleep is for patients who are mildly sleep-restricted, but do not suffer from serious sleep conditions such as insomnia or obstructive sleep apnea †.

Developed in collaboration with Physicians and researchers

 

SmartSleep was founded in 10 years of sleep research by industry leading experts and supported by four years of Philips research and development. Since its inception, Philips has worked closely with a scientific advisory board made up of world-renown sleep physicians and scientists. These experts have played a vital role in SmartSleep’s end-to-end innovation, advising Philips development teams on the science behind the functionality, as well as the design and analysis of experimental trials of SmartSleep in the laboratory and in the home.

In fact, the need for and approach to developing SmartSleep was primarily born from extensive research by Dr. Giulio Tononi showing that sleep slow waves can be enhanced by the delivery of auditory stimuli. His 2010 paper was a critical catalyst in the conceptualization of SmartSleep as an innovative device to use tonal stimulation to improve deep sleep quality in those who do not get enough sleep due to lifestyle.

 

At Philips, we see an opportunity to leverage advanced technology, coupled with scientific and consumer insights, to deliver solutions that improve people’s health and drive differentiated outcomes across the health continuum. Our scientific advisory board and the guidance they offer allow us to continue to improve lives through meaningful innovation that is truly rooted in science.

† SmartSleep should only be used by people who fall asleep within 30 minutes of trying to fall asleep; sleep at least 5 hours straight but less than 7 hours; don’t regularly wake up during the night; don’t use medications or alcohol to fall asleep and do not have hearing loss. Smartsleep is recommended for use for people 40 years of age and under.
