The objective was to create an ecosystem for objectively monitoring and improving medication adherence in adolescent transplant recipients using a lightweight wireless and wearable devise, worn around the neck. We designed and developed an early prototype (mockup) of a pharmaceutical adherence monitoring system in the form of wireless neckwear, equipped with off-the-shelf electronics. We tested the mock up device on healthy volunteers, and collected multimodal data, such as swallowing sounds, activity tracking, and heart-rate.
We evaluated several industrial neckwear designs in terms of appearance, functionality, and acceptability among potential users. We also developed user interface software and digital signal processing algorithms to derive meaningful data from the acquired signals. In consultation with the clinical team, we identified the key features to be included in the associated social environment, and identified cost and benefits of regularly wearing the proposed neckwear. However, we could not reach the stage to directly involve the end users.
