Smart pillow sleeve uses vibrations to alert deaf users to emergencies at night

Researchers at Nottingham Trent University developed a smart pillow sleeve for deaf sleepers.

Tiny haptic actuators inside the thin sleeve vibrate when connected alarms go off, helping wake users for emergencies like fires or intrusions.

The device uses distinct vibration patterns for different alerts and was tested for durability through washing.

It could improve nighttime safety for deaf and deafblind people without bulky devices that disrupt sleep.
