Wearables for Measuring an Itch

The presentation focuses on advancements in wearable technology for measuring itch and its correlation to scratching behaviors, a critical factor in dermatology. The speaker, a faculty member at Northwestern, discusses their startup, which collaborates with pharmaceutical companies to improve itch measurement methodologies. The complexities of scratching are highlighted, indicating that factors like intensity, frequency, and duration are essential for understanding patient experiences and outcomes. A survey of atopic dermatitis patients reveals that they prioritize measuring scratch intensity over duration or events. The speaker introduces innovative wearable sensors, specifically a device called Adam, which captures detailed data related to scratching, including acoustic signals to differentiate actual scratching from mere hand movements. Preliminary studies suggest the device can significantly reduce nighttime scratching, thus potentially minimizing skin damage. The presentation emphasizes the importance of incorporating patient feedback in the development of these technologies and posits that wearables could not only serve as measurement tools but also provide therapeutic benefits by helping to interrupt the itch-scratch cycle. Overall, the speaker advocates for a multifaceted approach to measuring itch that includes skin condition assessment, patient perception, and behavior while emphasizing the need for validated medical devices.
