Sleep Mask

Sana is a smart sleep mask that helps you to relax and quickly fall asleep. As a therapeutic wearable, it alleviates sleep related problems like insomnia, post-traumatic stress disorder (PTSD) and chronic pain.

Sana offers a completely non-invasive alternative through synchronised light and sound stimulation. Based on over 20 years of clinical research and development, Sana measures your heart rate variability and tailors the stimuli to enable you to relax and fall asleep, on average in less than ten minutes.

The mask houses two LED arrays, emitting a warm light of a particular wavelength, which can be experienced even with your eyes closed behind the mask. Bone conduction speakers placed at each temple transmit a synchronised audio signal directly into the head, meaning the mask can be used without disturbing anyone sleeping next to you. Sana is built around a flexible lightweight frame with a fabric clad EVA exterior and replaceable lining. Its slim profile and breathable foam padded interior makes it comfortable to wear, even when resting the side of your head on a pillow. A simple touch control interface allows the mask to be operated blindly, and recharging is done through a magnetically attached USB cable.

This design project was carried out in close collaboration with Sana, a UK based start-up, and the HAX hardware accelerator programme. The Sana sleep mask is currently undergoing final development, clinical trials and certification, with the aim to launch to the general public in early 2017.
