Texas professor Kaya de Barbaro is creating a mother-child wearable systemto detect and attempt to prevent postpartum depression. Mother stress levels are measured via heart rythm, and encouraging messages are sent. Mom wears the sensor on her wrist, and baby wears it on her/his ankle. The child’s sensor collects heart rate and movement data, which is correlated with the mother’s reaction. Audio is recorded to track crying. Mothers receive messages, including “great job” and “take a breather” when stress is sensed via a faster heart beat, in an attempt to limit feelings of isolation.
