The promise of remote health monitoring has long been tethered to a piece of hardware, a wearable sensor that patients must remember to charge and wear. Nervotec, a Singapore-based startup, is betting that the most ubiquitous sensor of all,the smartphone camera,can untether it. Founded in 2020, the company has developed software that uses a device's front-facing camera to measure heart rate, oxygen saturation, and other biomarkers through subtle changes in reflected light from the skin, a technique known as video-based photoplethysmography (PPG) [IMDA, June 2024]. For founder Jonathan Lau, a former fighter pilot, the goal is to make physiological monitoring as frictionless as taking a selfie.
This approach, which the company calls "Healthcare as a Service" (HaaS), targets a wide range of professional environments where continuous, contactless monitoring could provide safety or wellness insights [F6S, retrieved 2024]. Nervotec's early traction suggests a market receptive to the concept. The company has integrated its technology into Prudential's Pulse consumer app, allowing users to check their vitals, and worked with the construction giant Kajima to monitor worker health during the pandemic [IMDA, June 2024]. A more recent, ambitious partnership with Fischer Medical Ventures, firmed up in July 2024, aims to extend the platform's capabilities to screen for blood pressure, haemoglobin, and HbA1C levels through camera-enabled devices [Medgate Today, July 2024].
The Clinical Ambition Behind the Camera
The core technical bet rests on translating a well-understood optical principle into reliable, regulatory-grade software. Photoplethysmography detects blood volume changes under the skin by analyzing light absorption; smartwatch heart-rate sensors use a version of this with dedicated LEDs. Nervotec's innovation is to extract the same signal from the ambient light captured by a standard RGB camera, processing the subtle color variations in a user's face to estimate vital signs [IMDA, June 2024]. The company reports its underlying research was conducted in collaboration with Singapore General Hospital and the National University Health System and has been peer-reviewed in JMIR Formative [Business Post Nigeria, retrieved 2026].
This academic and clinical foundation is critical for Nervotec's stated roadmap. As of June 2024, the company reported its platform was "on track to being certified for medical use" for applications like telehealth consultations [IMDA, June 2024]. Achieving that certification would be the key that unlocks deployment in regulated healthcare settings, moving beyond wellness apps into domains where clinical decisions are made.
A Founder's View from the Cockpit
The company's origin story is distinctly human-centered, rooted in a specific, high-stakes need. Jonathan Lau conceived of the idea during his time as a fighter pilot, seeking a way to monitor pilots' vital signs and fitness to fly without cumbersome wearables [IMDA, June 2024]. While the initial vision involved wearables, the pivot to camera-based software emerged as a more scalable, accessible path. Lau's background is eclectic, spanning roles in fund management and talent acquisition, but the throughline is an operator's focus on solving a tangible problem [Bloomberg, retrieved 2026].
The team around him, while not extensively detailed in public records, includes individuals associated with the company on professional networks and an early-stage incubator portfolio listing [LinkedIn, retrieved 2026] [SMU Institute of Innovation & Entrepreneurship, retrieved 2024]. To date, Nervotec has raised a modest seed round. Public records conflict slightly on the total, citing amounts between approximately $144,000 and $180,000 from investors including the Huawei Spark Incubator Programme and She1K [CB Insights, November 2022] [F6S, retrieved 2024].

The Road to Medical-Grade Validation
The path from a promising research project and pilot deployments to a certified medical tool is steep. Nervotec's current publicly disclosed funding is lean for the costly clinical validation studies typically required by regulators like the FDA or Singapore's Health Sciences Authority. The company's next phase likely hinges on demonstrating the accuracy and reliability of its measurements in controlled trials to support a regulatory submission. Its research hospital collaborations are a necessary first step, but formal clearance would represent a significant inflection point.
The competitive landscape for remote patient monitoring is crowded with hardware-based solutions from established players like Philips and Apple. Nervotec's software-only, device-agnostic wedge offers a different value proposition:
- Lower friction adoption. No need to distribute or manage hardware; it works on devices users already own.
- Scalable screening. Potential for rapid, low-cost population health checks in corporate or insurance settings.
- Telehealth integration. Could provide objective vital sign data directly within a video consultation platform.
However, the very ubiquity of the camera is also a technical challenge. Factors like lighting conditions, skin tone, and user movement can affect signal quality. The company's algorithms must be robust enough to account for these variables consistently to meet medical-grade standards.
A Future in Chronic and Preventive Care
For patients managing cardiovascular conditions, hypertension, or chronic respiratory issues, the standard of care often involves sporadic clinic visits for check-ups or reliance on personal wearable devices that not everyone adopts. Continuous, passive monitoring remains an elusive goal. Nervotec's proposition, if clinically validated, could subtly shift that paradigm. It imagines a world where a routine video call with a doctor includes automated, contactless collection of key vitals, creating a richer longitudinal health record without asking the patient to do anything new.
The immediate patient population that stands to benefit is broad: from individuals in remote areas with limited clinic access to office workers in corporate wellness programs, and eventually to those with chronic diseases needing more frequent monitoring. The technology's application in workplace safety, as seen with Kajima, points to its preventive potential in high-risk industries. The next twelve months for Nervotec will be defined by progress toward that crucial medical certification. Success would not just validate its technology, but could redefine the hardware requirements for an entire category of digital health.
