Chipper, An Alarm Clock That Only Stops Ringing Once People Are Out of Bed

Chipper is an alarm clock by a group of students at California Polytechnic State University in San Luis Obispo, California that only stops ringing once people are out of bed. The device uses a fabric sensor to determine if someone is in the bed, and it will actually start ringing again if someone gets back into bed after getting out. The alarm times are controlled by a smartphone.

Instead of measuring force, pressure, or mechanical movement, the Chipper measures capacitance. This allow us to build a sensor that is cheaper to build, thinner, and sensitive to the entire bed.
