In recent years, the health-tech space has seen a surge of devices promising medical-grade insights at home. Yet, very few manage to combine advanced technology with true personalization and privacy. I recently spoke with Sunil Maddikatla, Founder of Eyva, a device that brings non-invasive health monitoring and AI-driven insights directly to users.
I wanted to understand how Eyva tracks key health markers, ensures data privacy, and delivers accurate, actionable guidance. Sunil walked me through the technology behind Eyva—from the smart sensors and AI algorithms to its cloud ecosystem and personalized health scoring. The conversation offered a clear view of how Eyva is designed to provide a truly personal and reliable health experience.
Here is what he shared:
What are the core technologies powering Eyva?
EYVA is powered by a proprietary blend of biosensing hardware, AI algorithms, and data analytics. The core technologies include:
- Non-invasive biosensors
- Artificial Intelligence (AI) for personalized health coaching and predictive analytics
- Real-time data processing and interpretation
- Personalized scoring systems for metabolic, cardiovascular, and respiratory health
- A smart-device + cloud ecosystem to deliver actionable insights
How does Eyva capture and process biometric or health data?
EYVA captures biometric data using integrated non-invasive sensors that track six key vitals. This data is then:
- Processed using on-device intelligence and proprietary algorithms
- Interpreted to generate personalized health scores
- Further analyzed in the cloud (as part of the ecosystem) to offer recommendations, predictions, and behavioral nudges.
What kind of sensors are integrated into Eyva, and what do they measure?
EYVA integrates non-invasive biosensors to measure:
- Blood glucose (World’s first non-invasive implementation)
- Blood pressure
- Electrocardiogram (ECG)
- HbA1C
- Heart rate (HR)
- Oxygen saturation (SpO₂)
These sensors are designed to assess metabolic, cardiovascular, and respiratory health through advanced signal acquisition and interpretation.
Is Eyva’s data processing done on-device, or is it cloud-based?
EYVA uses a two-stage data processing approach, prioritizing user privacy at every step. Initial processing is performed directly on the device to minimize data exposure. The remaining analysis and key algorithms are carried out on a securely encrypted cloud platform, protected by SSL protocols, ensuring both speed and confidentiality.
How does Eyva ensure the accuracy of its health readings?
EYVA ensures accuracy through an initial 30-scan profiling journey conducted over 3-6 days. During this phase, the device collects multiple vital markers alongside contextual data such as lifestyle habits and baseline HbA1c. Proprietary algorithms then create a unique biometric-lifestyle fingerprint for each user, recognizing that no two bodies are alike. This personalization allows EYVA to move away from a “one-size-fits-all” algorithm and achieve up to 90% accuracy in its readings once the profile is established.
Can you explain the data encryption or privacy protocols built into Eyva?
EYVA employs multi-layer encryption to safeguard all user data. As an ISO 13485-certified platform, we adhere to rigorous health device data security standards. All transmissions use 256-bit SSL encryption, ensuring that sensitive health information remains fully protected from capture to storage.
What platforms or operating systems is EYVA compatible with?
EYVA works seamlessly with both Android 8 and above and iOS devices including iPads, ensuring a smooth experience across the most widely used mobile platforms.
How does EYVA connect to other devices?
EYVA connects to the mobile app via Bluetooth Low Energy (BLE), enabling fast, reliable, and energy-efficient data transfer.
What is the battery life of EYVA and how long does it take to charge?
Under normal usage, EYVA’s battery lasts up to one week and fully recharges in about two hours using a standard power adapter just like charging your phone.
Are software updates for EYVA delivered automatically? How frequently are they rolled out?
EYVA is built for effortless upgrades. All improvements, new features, and optimizations are delivered directly through the mobile app, no manual firmware updates or technical steps required. Users simply tap “update” in the app, and EYVA stays continuously up-to-date, intelligent, and future-ready.
