iCalm: Wearable Sensor and Network Architecture for Wirelessly Communicating and Logging Autonomic Activity

Widespread use of affective sensing in healthcare applications has been limited due to several practical factors, such as lack of comfortable wearable sensors, lack of wireless standards, and lack of low-power affordable hardware. In this paper, we present a new low-cost, low-power wireless sensor platform implemented using the IEEE 802.15.4 wireless standard, and describe the design of compact wearable sensors for long-term measurement of electrodermal activity, temperature, motor activity, and photoplethysmography. We also illustrate the use of this new technology for continuous long-term monitoring of autonomic nervous system and motion data from active infants, children, and adults. We describe several new applications enabled by this system, discuss two specific wearable designs for the wrist and foot, and present sample data.

iCalm: Measuring electrodermal activity in almost any setting

The iCalm sensor is a wireless, wearable, washable wristband that can measure electrodermal activity and physical activity in almost any natural setting. This platform has many applications including health monitoring for outpatients, communication of affective information for people who are non-speaking or otherwise interested in sharing this information, education for individuals who want to learn about their own internal physiological changes during daily life, and customer experience data gathering in mobile situations.
