Monitoring people during sleep time is of particular interest to patients with sleep disorders and elderly people or
infants. We have developed a battery powered electronic system to monitor people in the bed, store the data and send
them through a wireless link to a PC. The resulting data will be subject to further analysis using pattern recognition
to evaluate the feasibility of using the system as an indicator of sleep quality. The system is able to detect presence
on the bed and movements and breathing of the patient. The changes in pressure distribution on the mattress cause
changes in pressure in the layers of the sensor and a voltage will appear on the electrodes. The detection ability depends
strongly on the shape of the mattress and the bedbase.
