The finished product aims to avoid the aesthetics of circuitry and instill confidence to the user. Final circuit schematic and more detailed photos are available in the final presentation available below.

The idea is that the BREATHING PAD can the baby monitor at the early infant period of parenting. As previously mentioned, the parent's anxiety during infancy is not easily qwelled with a classic audio or video baby monitor. To fabricate the device I utilized two wool pads with conductive embroidery on each. The pads act as the bread in a sandwich of anti-static plastic squares. Each cross embroidery then acts a pressure sensor and is connected back to the lilypad arduino.

BREATHING PAD
Brad Crane

The biggest fear a new parent has is the sudden loss of their baby. This comes in many forms, but seems to be most evident when the child (finally) goes to sleep for any significant amount of time. Checking that the child is "still breathing" is a right of passage in parenting. Presently, there is no good way to check if your child is still alive short of going in, risking waking them, and verifying that they are breathing / moving.

My project aims to provide a monitoring system that logs movement and sound by cell phone or computer. The movement and sound sensors will be embedded into a typical wool sleeping pad common in baby cribs. The pad is normally relegated to moisture protection placed between sheets and mattress, but in this case the BREATHING PAD adds monitoring functionality.

A matrix of pressure sensors provide feedback of movement, each previous state logged and compared to previous for continuous monitoring. In addition, a small embedded microphone tracks sounds and the lilypad tracks the time since last sound logged. All of this data is then forwarded to the user's computer interface for monitoring purposes.

While not perfect, the idea is that the BREATHING PAD can the baby monitor at the early infant period of parenting. As previously mentioned, the parent's anxiety during infancy is not easily qwelled with a classic audio or video baby monitor. In order to effectively design, build, and test the device in three weeks it is necessary to order materials soon. The materials are available either at the lab, sparkfun, or amazon. The baby component of the test environment should be here soon.
