Healthcare monitoring has traditionally relied on wearable devices, cameras, pressure mats, and other forms of physical intervention. While these technologies can provide valuable data, they also create persistent challenges around personal privacy, patient comfort, and daily compliance.

XZent Solutions is taking a fundamentally different approach. Co-founded by Saurav L. Chaudhari and Ketan Pise, the Pune-based deep-tech startup is developing privacy-preserving ambient sensing technology that monitors movement, occupancy, and physiological signals without cameras or wearable devices.

In a conversation with Indian Startup Times, Saurav Chaudhari discussed the journey from engineering research to commercial deployment, the challenges of making radio-frequency sensing work amidst real-world noise, and XZent Solutions’ vision for ambient intelligence in healthcare.

From Aerospace and Quantitative Systems to Healthcare Deep Tech

Saurav’s professional journey spans systems engineering, aerospace thermodynamics, and quantitative data analysis. His exposure to complex physical systems eventually led him and his co-founder Ketan Pise—collaborators since their engineering days at SSGMCE Shegaon in 2016—to examine a fundamental healthcare challenge: How can human presence and vital trends be monitored continuously without requiring people to wear devices or compromise their dignity?

The team began exploring Wi-Fi Channel State Information (CSI) to decode how subtle changes in the physical environment affect ambient wireless wavefields. This led to the development of PulsEye, XZent’s foundational contactless sensing platform.

The underlying physics is intuitive: when a person moves or breathes within a room, those micro-movements create subtle phase and amplitude perturbations in ambient Wi-Fi subcarrier signals. By analysing these wave variations at the edge, PulsEye extracts meaningful physiological and posture trends wirelessly.

The objective is straightforward: enable continuous, proactive awareness without making physical spaces feel like surveillance environments.

Moving From the Lab to the Real World

Building deep-tech algorithms in a controlled laboratory environment is one thing; making them operate reliably in active care homes and hospital wards is another.

For XZent Solutions, the transition from research to commercialisation involved extensive field immersion across Pune healthcare hubs. The team spent months working alongside nurses, care-home directors, and clinical staff to understand how monitoring technology fits into existing daily workflows.

According to Saurav, this stage was critical. A technically sophisticated product has limited value if it causes alert fatigue, requires complex IT setup, or disrupts caregiver routines.

This customer immersion led XZent to adopt a dual-product strategy: using PulsEye as their long-term ambient sensing engine, while engineering BedExit as an immediate, high-impact safety solution for fall prevention in elderly care and hospital recovery suites.

How Ambient Waves Sense Human Activity

For those unfamiliar with Wi-Fi sensing, the technology can be understood through an analogy: imagine dropping a pebble into a still pool of water—it creates ripples that reflect and change depending on obstacles in the basin.

Wi-Fi signals behave similarly. Human respiration, posture shifts, and movement alter the subcarrier wavefield in a room. XZent Solutions’ PulsEye platform captures these micro-perturbations to enable:

• Contactless respiration and wellness trend tracking: Monitoring subtle chest-wall displacements without skin contact.
• Presence, room occupancy, and mobility monitoring: Detecting movement across physical spaces completely wirelessly.
• Unobtrusive sleep and activity observation: Delivering continuous overnight visibility without disturbing resident rest.

The key differentiator: the individual never needs to wear or recharge a sensor, and the environment never records a single visual image or audio stream.

A “No Cameras, No Wearables” Architecture

Privacy is paramount in healthcare, senior living, and memory-care environments.

Continuous camera surveillance creates anxiety and compromises personal dignity. Wearables, on the other hand, suffer from compliance friction—residents frequently remove wristbands, forget to recharge them, or misplace them.

XZent Solutions addresses both vulnerabilities through hardware-embedded passive sensing:

• Zero Optical Capture: Systems operate in pitch darkness with zero camera lenses or microphones, ensuring full dignity and privacy.
• Proactive Lead Time with BedExit: To address immediate fall risks, XZent’s BedExit system uses kinetic load sensors installed under bed legs to track center-of-gravity plane shifts. It alerts caregivers 10 to 15 seconds before a resident’s feet touch the floor, transforming a post-fall panic into an actionable window for timely intervention.

The broader goal is not simply to record incidents after they happen, but to enable early human intervention while preserving patient dignity.

The Engineering Challenge: Conquering Real-World Noise

One of the steepest hurdles in deep-tech hardware is maintaining high accuracy outside clean laboratory conditions.

In real-world care settings, hospital beds experience mechanical stress, residents shift positions, visitors sit on bed edges, and room multipath signals constantly fluctuate. If an algorithm triggers on every minor movement, caregivers experience alert fatigue.

XZent overcame this by engineering custom steel mounting plates rated for 800 kg total bed capacity and developing proprietary edge-filtering algorithms. Running directly on local microcontrollers, these algorithms calculate two-dimensional center-of-gravity velocity vectors within seconds, filtering out transient movement and triggering only on sustained intent to exit.

Privacy Built Directly Into Silicon

Healthcare data comes with strict data-protection responsibilities. Saurav emphasizes that trust cannot be earned through marketing promises alone—it must be enforced by physics and silicon.

XZent Solutions ensures privacy and security through three core pillars:

• Local Edge Processing: Raw sensor signals are processed directly inside the room on local microcontrollers; only lightweight, encrypted event alerts are transmitted.
• Silicon-Level Security: Microcontrollers utilize hardware Flash Encryption and Secure Boot v2, cryptographically protecting firmware against tampering and extraction.
• Zero Facility IT Dependency: BedExit communicates over a dedicated local wireless mesh link, functioning reliably even if facility Wi-Fi or internet connection is down.

Scaling Across India with Strong IP Foundations

XZent Solutions is now transitioning from initial pilot validation to commercial scaling:

• Commercial Rollout: Expanding its BedExit system across 18 major Indian cities, targeting care homes and hospital recovery wards across an addressable market of 1.35 million beds.
• Proprietary Intellectual Property: The company filed Patent Application 202521106451 (‘A Contactless Vital Sign Monitoring System and a Method Thereof’), published in February 2026 under the Government of India’s SIPP scheme.
• Institutional Recognition: XZent’s technology development has been recognized and supported with awards from STPI, UNICEF, and the IIT Bhubaneswar Research & Entrepreneurship Park.
• Capital Efficiency: Operating on a high-margin, customer-advance hardware model, XZent is currently engaging with strategic seed-stage investors to accelerate manufacturing and geographic expansion.

Building the Future of Ambient Intelligence

Looking ahead over the next five years, Saurav envisions XZent Solutions becoming a global leader in privacy-preserving ambient intelligence for care environments.

The company’s platform roadmap aims to integrate PulsEye’s room-scale sensing and BedExit’s kinetic safety into an intelligent software layer envisioned as IntentOS—enabling hospital wards, assisted-living facilities, and residential spaces to adapt lighting, safety protocols, and caregiver workflows automatically.

A New Model for Invisible Healthcare Monitoring

The evolution of XZent Solutions reflects a broader shift taking place in healthcare technology: from devices that people actively wear and maintain to intelligent environments that work quietly in the background.

Wi-Fi sensing and kinetic edge intelligence may not replace every diagnostic tool, but their ability to operate without cameras and wearables opens up unprecedented possibilities for continuous health, safety, and activity monitoring.

As XZent Solutions works towards scaling across India and preparing for international markets, its journey highlights a defining question for modern healthcare technology: Can technology become far more protective by becoming completely invisible?

XZent Solutions is proving that it can.
