Wellness Wearable
8 Months
- Continuous health tracking
- Personalised wellness insights
- Designed for everyday comfort
Key Outcomes
Developed the world’s first smart ring purpose-built for mindfulness using patent-pending micro-vibration patterns instead of data tracking with a team that includes former Oura Gen 2 engineers
Achieved 14-day battery life in a polished titanium ring form factor with BLE app connectivity, accelerometer tap activation, and wireless USB-C charging
Launched on Kickstarter with three distinct modes (Mindfulness, Meditation, Focus) and a companion app for intention setting and expert-guided courses
The Challenge
Before partnering with Iottive, Pulse Ring was facing several issues:
Anti-Tracking Design Philosophy
Unlike every other smart ring on the market (Oura, Ultrahuman, Samsung Galaxy Ring), Pulse Ring deliberately collects zero biometric data. This inverted design philosophy required building wearable firmware that drives actuators (vibration motors) rather than sampling sensors — the opposite of conventional wearable engineering.
Micro-Vibration Pattern Engineering
Pulse Ring’s patent-pending vibration patterns — including frequencies mimicking a purring cat, proven to reduce stress — required precise motor control at varying amplitudes and frequencies within a ringsized enclosure, constrained by power, heat, and acoustics.
14-Day Battery in a Ring Form Factor
Delivering two weeks of battery life from a ring-sized LiPo cell while driving vibration motors multiple times per hour demanded extreme power optimisation — every microamp of idle current mattered.
Kickstarter Credibility and Timeline
Hardware Kickstarter campaigns live or die on demonstrating a working prototype. Pulse Ring needed a fully functional demo unit — not a mockup — ready for the campaign launch, with a realistic manufacturing timeline that backers would trust.
Our Solution
Iottive delivered a complete AIoT solution under a full-cycle product development model.
Bluetooth/IoT Expertise
Implemented ultra-low-power BLE communication for mode selection,vibration pattern customisation, and firmware updates, optimized for the ring’s antenna constraints. BLE is active only during app interaction — the ring operates independently the rest of the time, preserving the 14-day battery target.
Design Thinking Approach
Collaborated with Pulse Mindfulness’s wellness advisors to translate mindfulness practices into haptic patterns. Each vibration sequence was tested with meditation practitioners for effectiveness — not just technical accuracy — ensuring the ring’s prompts genuinely support present-moment awareness.
Project Planning & Execution
Structured the timeline around Kickstarter launch requirements: working prototype (10 weeks), campaign demo units (4 weeks), manufacturing-ready firmware (8 weeks post-campaign). Coordinated with Haltian (Oura Gen 2 hardware partner) on ring enclosure and charging dock design.
Functionalities Delivered
Three modes — Mindfulness (random vibration reminders to pause and breathe), Meditation (guided vibration sequences replacing audio guidance), and Focus (timed vibration intervals for deep work sessions). Companion app for mode selection, intention setting, vibration pattern customization, and expert mindfulness courses.
Implementation Highlights
Sensors & Hardware
Linear resonant actuator (LRA) vibration motor with patent-pending drive patterns. Accelerometer for tap-to-activate gesture recognition. Polished titanium enclosure, water-resistant, wireless USB-C charging dock.
Edge & Connectivity
BLE used exclusively for app-to-ring configuration. Ring operates fully autonomously between app sessions — all vibration patterns execute from on-ring firmware with no phone dependency.
Firmware & Performance Optimization
Custom RTOS with <5μA sleep current. Vibration motor driven by PWM with amplitude and frequency envelopes stored as compact pattern tables in flash memory. 14-day battery life achieved through dutycycle optimisation the motor runs for milliseconds, the ring sleeps for minutes.
Data Analytics & Visualization
App tracks mindfulness session counts, streak days, and mode usage — all stored locally on the phone with no cloud upload, consistent with Pulse Ring’s zero-tracking philosophy.
Dashboard & UX
Companion app with clean, minimal interface reflecting Pulse Ring’s calm technology philosophy. Mode selection, vibration intensity adjustment, daily intention setting, and curated mindfulness courses from expert practitioners.
Security & Compliance
No biometric data collected, transmitted, or stored — by design. BLE pairing with bonding. Local-only app data storage. Calm Tech certified.
Results & Impact
- Kickstarter campaign launched with fully functional prototype units demonstrating all three modes
- 14-day battery life validated in real-world testing with multiple daily vibration sessions
- Patent-pending vibration patterns differentiated Pulse Ring from every other smart ring on the market
- Zero-data-tracking position resonated with privacy-conscious consumers fatigued by biometric wearables
- Partnership with Haltian (Oura Gen 2 engineers) provided hardware credibility that supported backer confidence
“Every other smart ring tracks your sleep and heart rate. We wanted to build something that helps you be present — not give you more data to stress about. Iottive’s firmware team turned our mindfulness vision into precise vibration patterns that feel like a gentle tap on the shoulder.Their power optimization gave us 14 days of battery, which means users wear it and forget it’s technology — exactly what we intended.”

Lessons & Best Practices
Constraint Drives Innovation
Building a wearable that deliberately avoids sensors forced creative solutions — vibration patterns became the product’s primary interface, not data dashboards.
Test Haptics with Practitioners
Vibration patterns that were technically precise weren’t always experientially effective. Testing with meditation practitioners — not just engineers — shaped the final pattern library.
Autonomous Operation Preserves Battery
Minimizing BLE radio usage by running vibration patterns from on-ring firmware — rather than streaming from the app — was the single largest contributor to the 14-day battery target.
Hardware Kickstarters Demand Working Prototypes
Backers have been burned by vapourware. Shipping fully functional demo units for the campaign video and press reviews built trust that a concept-only campaign could not.
