| # TITLE: Smart Pillow # TEAM MEMBERS: - Karan Samat (karanas2) - Aniketh Aangiras (aniketh3) - Trusha Vernekar (tnv2) # PROBLEM As technology advances, more people tend to use devices such as their phones or laptops right before going to bed. Studies have shown that sleep is affected drastically due to the use of technology in the hour before going to bed. People have reported less satisfactory sleep which causes them to be sleepier during the day. Some studies have also shown that bright screens can have an impact on alertness which can lead to users having disrupted sleep more often. Repeated dissatisfactory and disrupted sleep can lead to conditions such as sleep apnea. This is a growing concern due to the increase in the use of technology and can be dangerous. The signs that a person is not having satisfactory sleep can be loud snoring and frequent changes in sleeping positions. One way that can improve sleep is by listening to relaxing music or some peaceful podcasts. However, you cannot be sure when you would be having disrupted sleep. Smartwatches do a good job of detecting your sleep cycle but they must be charged very often and they are not able to help you improve your sleep. # SOLUTION To fix the above-stated problems, we propose the implementation of a smart pillow. Through this smart pillow, we aim to not just track sleeping habits, but also improve them. We will track the sleeping habits of the user through the following sensors: touch sensor, audio sensor, and pressure sensor. In addition to these sensors, we will also use a Bluetooth speaker that can play white noise or any other sounds/music that the user feels comfortable with to aid sleep. The audio sensor will be used to detect snoring. The touch sensor will be used together with the pressure sensor to determine the various sleeping positions of the user. This will then help us determine the quality of sleep of the user at each sleeping position. We believe that our idea stands out from what is already available today through the usage of the Bluetooth speaker system and the fact that this is more cost-effective. Most devices that are currently available include mattresses and smartwatches. However, these are significantly more expensive and do not provide a speaker system. We will be using a power system to regulate the power of each sensor subsystem. Hence we will have to use a PCB since it contains all the logic related to the sensors and the power modules. # SOLUTION COMPONENTS ## SUBSYSTEM 1 : THIN FILM PRESSURE SENSOR SUBSYSTEM This subsystem will help detect if a person is moving in their sleep. Many pressure sensors will be uniformly scattered across the pillow to detect minute changes in motion which will be reinforced by the touch sensors. Components: Pressure Sensor ## SUBSYSTEM 2 : TOUCH SENSOR SUBSYSTEM This subsystem will help detect if a person is moving in their sleep. Many touch sensors will be uniformly scattered across the pillow to detect minute changes in motion reinforced by the pressure sensors. Components: Touch sensor ## SUBSYSTEM 3 : AUDIO SENSOR SUBSYSTEM This subsystem will help detect snoring and will have to filter out noise. It will be enabled if the speaker is switched off or will start up after the speaker plays out for 1 hour. Components: audio sensor ## SUBSYSTEM 4 : BLUETOOTH SPEAKER SUBSYSTEM This subsystem will connect to a phone/device and allow the user to play the music of their choice. This can be a podcast or something similar. As an isolated system, it will be expected to play the sound until stopped by the user. Components: Stereo Bluetooth module, SMD amplifier, lithium-ion battery module, sliding switch, 3W speaker ## SUBSYSTEM 5 : POWER SUBSYSTEM This subsystem will be responsible to supply power to the different components of the device. Components: Lithium-ion battery module, USB charger/port, Battery controller, Boost/buck converters # CRITERION FOR SUCCESS - Detection Accuracy - We should be able to correctly detect the snoring sounds and change in sleep positions with a high enough accuracy. - Battery life - We will ensure that the battery life is enough to last the night and maybe more based on the hardware component choice. - Comfort - The pillow, after the addition of the sensors, should still be flexible and light. It should allow for good sleep. |
