Kick Ring LL: A Multi-Sensor Ring Capturing Respiration, Electrocardiogram, Oxygen Saturation, and Skin Temperature1.

With the growing trend towards personalized health, wearable fitness trackers have become a staple of the consumer electronics industry. As the prevalence of such devices booms, the medical community has been compelled to investigate the potential of such devices and explore how they can be used to create positive clinical outcomes. In this report we detail a smart-ring capable of determining heart rate (HR), respiratory rate (RR), blood oxygen saturation (SpO2), and temperature. The ring implements a photoplethysmogram (PPG), electrocardiogram (ECG), and thermistor to attain these metrics. After evaluation, significant correlation was found between the experimentally reported HR and RR recordings with their respective standards (p<0.05). Experimentally derived SpO2 had trial-dependent similarities with its reference standards, and temperature measurements were within expected values of normal skin temperature.

NeoWarm: Kangaroo Mother Care with Continuous Temperature Tracking and Heating.

Premature births are highly prevalent; world-wide, one in every ten births is premature. A common complication of premature birth is the inability of the newborns to regulate their own body temperature (hypothermia). Kangaroo Mother Care (KMC) is an effective strategy to mitigate this problem but has challenges. Namely, KMC requires constant engagement from the caregiver in order to keep the baby warm and to monitor the baby's temperature every 4 hours. In this report we describe NeoWarm, a device designed to address these challenges via continuous integrated warming and automated temperature monitoring of the infant, both during KMC and when the caregiver takes a break. Pilot studies demonstrate the ability of the device to warm a simulated newborn from moderate hypothermia to ideal core temperatures within two hours.
