Smart maternity wear (lily kickee): a wearable device sensing and visualizing fetal movements

This study purposed to develop smart maternity wear, which is a wearable computer that senses and visualize fetal movements, and to evaluate its usability. Before making the prototype, we conducted a preliminary survey and, based on the results, visualized fetal movements intuitively in the form of fetal footprint. The prototype was built with Lilypad Arduino, conductive thread, pressure sensor, and various LED's, and then its usability was tested. When satisfaction, fitness, practicality, intuitiveness, and sympathy were evaluated with 50 participants, the use of the smart maternity wear was found to enhance the level of empathy and increase communication among the family members.
