CAP-XX, a developer of supercapacitors that deliver peak power to support or replace batteries, has announced that Spire has incorporated CAP-XX Thinline supercapacitors into the new Spire Health Tag to provide the peak power needed for delivering real-time wellness vibration alerts to consumers. Offloading this peak power role to the thin, flat supercapacitor allows Spire to keep the battery small to achieve the ultra-thin form factor of its new wearable fitness biosensor that attaches to clothes once, can be washed as normal and needs no charging. Spire demonstrated its Spire Health Tag at CES in Las Vegas during January 9-12, 2018.
The tag’s 3 V coin cell battery continuously trickle charges the CAP-XX Thinline HA114 supercapacitor (0.8 mm thin, 120 millifarads, 130 milliohms), which then provides the peak power (100 milliamps initially, dropping to 40 milliamps for 400 milliseconds) for driving the motor that delivers vibration alerts consumers can set to help manage stress or monitor their heart rate.
Spire Health Tag aims to disappear unless it has something important to say in the moment. The tags use advanced algorithms, deep learning and proprietary respiratory sensors to provide personalized, real-time health guidance for sleep, stress and daily activity by continuously analyzing breath and heart rate inflection points.
Users set their goals in the accompanying mobile app’s to stay active, reduce stress, sleep better, get fit, stay calm and follow heart health programs. Spire’s Health Insights Engine monitors patterns and then suggests actions to help users toward their goals, either on the app or via physical vibration alerts for monitoring more critical situations like an athlete’s heart rate or potential panic attacks. Users set their own thresholds and frequencies for their vibration alerts. If Spire detects bio-signals related to stress or another specific health variable in the user’s breathing pattern it sends a vibration alert.
The supercapacitor’s low leakage current (less than 1µA) helps maximize the non-replaceable coin cell battery’s life, which will last about 18 months. Users can return expired tags to Spire and get a discount on replacements, and Spire will recycle and reuse all components and materials. The tags are to ship in March and are available for pre-order at $99 (three pack), $199 (eight pack) or $299 (15 pack).
