Smart Fabric Bellyband

belly band

Another example of a product currently under development is a maternity smart fabric bellyband to monitor uterine activity and assess fetal wellbeing. This project leverages conductive yarns, knitting technology and the use of a passive radio frequency identification (RFID) tag. The aim was to create of a wearable wireless telemetry device that reduces bulk, improves comfort and enables greater mobility in pregnant women. The wearable, battery-less wireless sensor would replace the current cumbersome wired probes for contractions and respiration monitoring. The first step in the bellyband design was to experiment with digital fabrication of different antenna shapes knitted with conductive yarns that connect to the passive RFID. We considered a multitude of conductive pathway designs for our antenna including the final design in the form of a folded dipole antenna.
