Scientific progress has significantly reshaped our perception and interaction with the world. Camera development has transformed visual capture and interpretation, while speaker technology has elevated auditory experiences. But there’s a noticeable gap when it comes to olfactory senses, leaving smell largely untapped in technological innovation.

This is where EC-Sense GmbH steps in.

EC Sense specializes in the development, manufacturing, and distribution of versatile gas sensors and sensor modules tailored for diverse applications. These applications span from monitoring air quality shifts to alerting systems for various gases. The sensors find utility in a spectrum of scenarios, such as indoor air quality, smart home technologies, outdoor air quality assessments, environmental protection measures, industrial gas monitoring, fire protection systems, and integration within industrial 4.0 and IoT applications.

The Heart of EC Sense’s Innovation

Electrochemical sensor technologies continue to be increasingly used for many different analytical gas detection applications, such as personal monitoring. A low-cost sensor with a simple user interface, small size, and minimal power consumption is in high demand. The majority of these sensors are amperometric sensors that have measuring and counter-reference electrodes and liquid electrolytes.

However, it is noteworthy that liquid technology in sensor production involves considerable manual labor and presents challenges such as the persistent risk of electrolyte leakage from the housing. Despite these challenges, since 2022, the global usage of electrochemical Gas Sensors has surpassed 30 million, underlining their widespread adoption and impact.

The EC Sense solid polymer electrochemical technology steps up to fill this void. The revolutionary innovative technology is based on the principle of electrochemical catalytic reaction, detecting the output signals of the electrochemical reactions of different gases and accurately measuring the gas concentration through the signal.

“The liquid core was completely polymerized and is therefore ready for use for any type of application in any size or format,” says Koller.

EC Sense offers two types of electrochemical sensors – a polymerized version designed for leak-free, no-dry-out, and small applications and a standard liquid electrochemical sensor version with improved protection against leakage and higher accuracy.

Key Features and Advantages of the Solid Polymer Electrochemical Technology

The sensors, based on solid polymer electrochemical technology, offer a distinct advantage when it comes to gas detection. In contrast to competing technologies like MEMS or semiconductor sensors, its electrochemical sensors are best suited for comprehensive, town-wide pollution detection.

Their competitive pricing makes them an attractive option compared to MEMS sensors. The reliability and speed of response of EC Sense sensors sets them apart, as they are unaffected by poison, have a lifespan of five to 10 years, and can handle a wide range of gases.

A notable feature that sets EC Sense sensors apart is their zero baseline, indicating no readings when gas is absent. This stands in stark contrast to MEMS sensors, which tend to continuously register readings, often resulting in drift issues when exposed to background gases. The zero baseline of EC Sense sensors enhances their accuracy and reliability by providing a clear reference point even in the presence of small gas concentrations. This addresses a common challenge faced by MEMS sensors in maintaining precision over time. EC Sense sensors also boast lower power consumption, eliminating the need for heating, which is typical in MEMS sensors. This makes them ideal for battery-powered devices.

Compared to other electrochemical sensors, the solid polymer electrochemical sensors come with a small footprint to fit into a wide range of applications. Specifically in fire protection, the small solid polymer sensors have the advantage of a lifespan exceeding ten years, a testament to their robust design.

EC Sense boasts a remarkably efficient and automated production process, churning out an impressive 25,000 sensors within a mere two and a half hours. This exceptional capability has led to a substantial increase in their annual production volume. The growth trajectory is particularly notable as it reflects significant expansion over the last four years.

Applications and Impact

EC Sense’s advanced technology makes a tangible difference across five pivotal segments—industrial safety, industrial farming, hydrogen detection, semiconductor industry, and indoor & outdoor air quality monitoring. Its commitment to safety, health, and environmental quality is evident in each area.

In industrial safety, EC Sense’s sensors play a crucial role in safeguarding industrial processes by detecting and managing potentially hazardous gases and substances. This prevents accidents and ensures a secure working environment for employees. A critical need in industrial farming is addressed by controlling air quality and promoting animal health and welfare.

Another application are the semiconductor industry, laboratories, and educational institutions. They utilize EC Sense’s solid polymer electrochemical sensors for precise gas monitoring to support safe production, research, experimentation, and education of scientists and engineers. EC Sense’s presence in this sector highlights its commitment to advancing scientific knowledge and technology.

EC Sense’s technology enhances the ability to understand and address urban air pollution by providing accurate, real-time data. This contributes to healthier urban environments and empowers communities to take action to improve air quality, demonstrating a commitment to environmental sustainability and the well-being of urban populations. This equally applies for monitoring the indoor air quality.

“With each innovation, we are inches closer to our vision of improving air quality and reshaping the way we perceive and interact with our environment,” says Koller.

A main focus that has emerged recently is hydrogen detection. EC Sense just released a new hydrogen sensor detecting the gas from very low up to a very high range of gas concentration. “Our company believes hydrogen will be a fuel in the future, a real fuel next to gasoline,” says Peter Koller.

Polymerization is a key component used to create electrochemical gas sensors, allowing them to be adapted for any applications in any size or format

The Vision of Accessibility and Sustainability

One of EC Sense’s overarching ambitions is to make clean air sensor technology widely accessible, with a focus on affordability and integration. It strives to reduce the cost of its sensors and make them easier to incorporate into existing products. This vision aligns with its goal of enabling more people to benefit from the advantages of clean air monitoring, ultimately contributing to a healthier and safer world.

Electrochemical sensors have emerged as the global standard for safeguarding both individuals and machinery, primarily designed for detecting typical Threshold Limit Values (TLV). Years of development have contributed to the exceptional reliability, selectivity, and durability of these sensors.

Their inherent direct linearity, where an increase in gas concentration correlates with a proportional signal increase, has facilitated the construction of both portable and stationary detectors by equipment manufacturers.

Moreover, EC Sense’s team has undergone considerable expansion, currently comprising 25 members in Germany and an additional 55 in China. This growth not only showcases the company’s success but also underscores its commitment to scaling operations globally and establishing a presence in key markets.

As EC Sense continues to grow and innovate, its commitment to accessibility, safety, and environmental well-being positions the company as a significant force in making the world a cleaner, safer, and more sustainable place for all.
