Constant pregnancy monitoring is a promising alternative to reduce the number of stillbirths and preterm delivery due to false alarms. Tele-monitoring systems can provide regular, accurate and timely monitoring to re-duce risks, costs and the time the mothers-to-be spend at hospitals.

Based on those requirements, several garment alternatives for the monitoring system are proposed and evaluated
