B-Secur Launches ECG Test System to Improve Signal Quality Testing for Wearable Devices
B-Secur, a leader in advanced biosensing technology, has launched its new ECG Test System (ETS), a reference-based performance testing platform designed to help wearable device manufacturers objectively measure and standardize electrocardiogram (ECG) signal quality throughout the product development lifecycle.
The launch addresses a growing challenge within the wearable technology industry. ECG functionality has become an increasingly common feature in consumer wearable devices, with millions of people using smartwatches and other wearable technologies capable of capturing cardiac signals. However, despite the widespread adoption of ECG-enabled wearables, manufacturers have not had a universally agreed method for determining whether the signals captured by their devices meet consistent quality expectations.
B-Secur’s ETS is designed to help close that gap by providing manufacturers with a controlled and repeatable approach to ECG signal quality testing. The system is intended to support engineering teams from early bench testing through later stages of development and production quality control.
Addressing a Growing ECG Signal Quality Challenge
The introduction of ECG capabilities into wearable devices has created significant opportunities for health monitoring and digital health applications. Wearables can capture physiological data outside traditional clinical environments, giving users and healthcare-related technology companies access to information that can potentially support a range of applications.
However, capturing an ECG signal through a wearable device presents technical challenges.
Unlike traditional clinical ECG equipment, wearable devices are designed to operate in everyday environments. Users move, exercise, sweat, change positions, and interact with their devices under a wide range of conditions. These factors can affect the quality of the signal captured by wearable sensors.
For manufacturers, ensuring that an ECG-enabled product consistently produces a high-quality signal is therefore an important part of product development.
According to B-Secur, one of the key problems facing the industry is the absence of an agreed testing methodology and shared benchmark for evaluating ECG signal quality in wearable devices.
Without a consistent reference point, manufacturers may have difficulty comparing performance, identifying weaknesses early, and determining whether improvements made during development have delivered measurable gains.
B-Secur developed ETS to provide a standardized framework that can be applied across different stages of product development.
From Early Design to Production Quality Control
One of the central features of the ECG Test System is its ability to support testing throughout the development process.
Wearable products typically move through multiple stages before reaching consumers. Early engineering teams may begin with bench testing and prototypes, followed by design refinement, validation, and eventually production.
Signal quality issues that remain unidentified during the early stages can become significantly more difficult and expensive to address later.
When a problem is discovered during late-stage validation, manufacturers may have to make hardware or software changes, repeat testing, adjust development schedules, or potentially undertake additional product iterations.
B-Secur says ETS is intended to help manufacturers identify these issues earlier.
By providing a consistent testing methodology, engineering teams can assess ECG signal performance at different development milestones. This allows manufacturers to work with measurable evidence rather than relying primarily on assumptions about how a wearable’s ECG system will perform.
The approach can also provide a framework for quality control as products move closer to commercial production.
Creating an Objective Measurement Framework
A major objective behind ETS is to introduce greater objectivity into ECG signal quality assessment.
Wearable manufacturers need to understand how effectively their devices capture ECG signals, but meaningful evaluation requires controlled conditions and reliable reference points.
The B-Secur system is described as a reference-based performance test system. Its purpose is to provide manufacturers with an objective and standardized measure that can be used to assess signal quality.
This can be particularly important when engineering teams are comparing different hardware configurations, sensor arrangements, algorithms, or product designs.
Instead of evaluating signal performance solely through isolated tests or subjective observations, teams can use a consistent testing framework across development stages.
Such consistency can help organizations establish clearer internal performance expectations and identify potential signal-quality problems before they become larger development issues.
Wearables Are Expanding ECG Access
The growth of ECG functionality in consumer wearables has changed how cardiac data can be collected.
Smartwatches and other wearable devices can place sensing capabilities directly on a user’s body, enabling data collection outside hospitals, clinics, and traditional medical environments.
This expansion has contributed to growing interest in wearable ECG technology across consumer health, digital health, medical technology, and biosensing markets.
At the same time, the increased use of ECG features places greater importance on the quality of the underlying signal.
An ECG measurement is only useful when the device can capture a signal of sufficient quality for its intended purpose. Poor signal quality can make interpretation more difficult and may limit the usefulness of downstream applications.
For manufacturers, this creates a need to evaluate signal performance systematically throughout development.
B-Secur’s ETS is positioned as a tool to support that process.
Industry Experts Highlight the Importance of Signal Quality
The challenges associated with ECG signal quality were recently discussed during an industry roundtable hosted in September by Blythe Karow of the Device Files.
The discussion brought together several experts from healthcare, electrophysiology, wearable technology, and digital health.
Participants included Prof. David Burke, Director of the Digital Health Institute at the Beacon Hospital in Dublin; Dr. Kenneth Civello, an electrophysiologist and wearable device expert; and Sam Sheng of Google.
The roundtable examined the clinical implications of poor ECG signal quality as well as the practical difficulties manufacturers face when trying to maintain consistent signal performance throughout product development.
The discussion highlighted the importance of having reliable methods for evaluating ECG signals before wearable products reach later stages of validation.
For manufacturers, signal quality is not simply a technical consideration. It can influence how effectively a wearable performs its intended function and how confidently companies can evaluate the performance of their sensing technology.
B-Secur’s ETS directly responds to the standardization and benchmarking challenges identified during the industry discussion.
Reducing Late-Stage Development Risk
One of the most important potential benefits of a standardized testing approach is earlier identification of problems.
Product development involves significant investment in engineering resources, testing, manufacturing, and validation. When a technical issue is discovered late in the development cycle, correcting it can require additional time and resources.
ECG signal quality can be influenced by numerous factors, making early testing particularly important.
For example, changes to the wearable’s design, sensor configuration, software, algorithms, or other components may affect how effectively ECG signals are captured.
A standardized testing system can give engineering teams a way to evaluate these changes more consistently.
By testing performance at earlier stages, manufacturers can potentially identify weaknesses before they become embedded in later development work.
B-Secur’s approach is intended to help companies move through development phases with greater evidence and confidence.
Rather than waiting until late-stage validation to determine whether an ECG system performs as expected, teams can incorporate signal quality testing into their development process from the beginning.
Supporting Engineering Teams
The ECG Test System is designed specifically to address the needs of engineering teams developing wearable products.
During early development, engineers often need to test prototypes repeatedly as they make changes to hardware and software. Having a repeatable testing framework can help teams compare results between iterations.
As products mature, the same type of testing can support validation and quality assurance.
This continuity is important because signal quality should not be treated as a single development milestone. Performance needs to remain consistent as a product evolves from prototype to production.
ETS is intended to provide manufacturers with a common methodology that can be applied across these stages.
That gives teams an opportunity to establish a more structured approach to ECG performance evaluation.
The Importance of Standardization
The lack of shared benchmarks has been an ongoing challenge for wearable ECG technology.
Manufacturers may use different approaches to assess their devices, making it difficult to compare performance consistently across products.
A standardized methodology can help address this issue by establishing a common framework for testing.
For the broader wearable industry, greater standardization could also support clearer communication around ECG signal performance.
As wearable ECG technology continues to develop, manufacturers, technology companies, researchers, and healthcare stakeholders all have an interest in understanding how reliably devices capture physiological signals.
B-Secur’s launch of ETS represents an effort to contribute to that standardization by giving manufacturers a structured method for measuring ECG signal quality.
Supporting the Next Generation of Wearable Technology
The wearable technology market continues to evolve as manufacturers add increasingly sophisticated health-monitoring capabilities to consumer devices.
ECG is one of the technologies that has moved from specialized medical equipment into consumer-facing wearable products.
As adoption increases, technical performance becomes increasingly important.
Manufacturers must consider not only whether a device can capture an ECG signal but also whether that signal can be captured consistently and evaluated objectively.
This creates an opportunity for testing technologies such as B-Secur’s ETS to become part of the development infrastructure behind wearable ECG products.
By enabling testing from early bench development through production quality control, the system is intended to help companies build signal-quality assessment into their product development processes.

ECG signal quality is particularly significant because the data captured by the sensor forms the foundation for subsequent analysis and applications.
B-Secur’s ECG Test System is designed to provide manufacturers with a more controlled way to evaluate that foundation.
The company believes that providing objective and standardized testing can help address an important gap in the wearable industry.
Building Confidence in ECG Wearables
The launch of ETS comes as ECG-enabled wearables continue to become more widespread.
With tens of millions of people using consumer wearables that include ECG functionality, the quality of the signals produced by these devices has become an increasingly important industry consideration.
Manufacturers need tools that can help them understand signal performance before products reach consumers.
B-Secur’s ECG Test System is positioned to provide that capability by establishing a consistent testing methodology and reference-based performance assessment.
The system can be used throughout product development, from initial bench testing through production quality control, helping engineering teams evaluate signal quality at multiple stages.
Ultimately, the launch reflects a broader shift in wearable technology toward more rigorous measurement and validation.
