The sensor, developed by a team led by Professor Tawfique Hasan from the Cambridge Graphene Centre, boasts the ability to detect formaldehyde in real time at levels as low as eight parts per billion.&nbsp;
This surpasses the sensitivity of many existing indoor air quality sensors, providing a crucial tool for identifying potential health hazards in various settings.
Aerogels, known for their highly porous structure, serve as the foundation for these cutting-edge sensors.&nbsp;
By intricately shaping the cavities within aerogels, the researchers achieved precise detection of formaldehyde at ambient temperature.&nbsp;
This method enables the selective detection of formaldehyde, a common VOC found in household items like MDF, wallpapers, paints, and synthetic fabrics.

The prototype sensors operate on minimal power, making them suitable for a range of applications, including wearable and healthcare devices.&nbsp;
The team envisions the miniaturization of these sensors for widespread deployment, offering real-time monitoring of indoor air quality to mitigate health risks associated with VOC exposure.
Volatile organic compounds (VOCs) present a significant indoor air pollution risk, contributing to symptoms such as eye irritation, throat discomfort, and respiratory issues.&nbsp;
Prolonged exposure to certain VOCs, including formaldehyde, can lead to severe health implications such as asthma exacerbation and increased cancer risk.&nbsp;
With a considerable portion of households exceeding recommended formaldehyde limits set by the World Health Organization (WHO), the need for precise monitoring solutions is paramount.

The collaboration between the University of Cambridge and Warwick University has yielded promising results in the development of low-cost, multi-sensor platforms incorporating the novel ‘frozen smoke’ material.&nbsp;
By integrating quantum dots into the aerogel structure and employing machine learning algorithms, the researchers have enhanced the sensor’s sensitivity and selectivity.&nbsp;
This breakthrough enables the differentiation of formaldehyde from other VOCs, paving the way for more comprehensive environmental health assessments.
Supported by the Henry Royce Institute and the Engineering and Physical Sciences Research Council (EPSRC), this research signifies a significant step forward in detecting hazardous materials and assessing air quality with greater precision.&nbsp;
The application of AI algorithms further enhances the sensor’s capabilities, offering a holistic approach to monitoring indoor environments for potential health risks associated with VOC exposure.
The development of the ‘frozen smoke’ sensor represents a remarkable achievement in environmental science, promising tangible benefits for public health and safety.&nbsp;
With its unparalleled sensitivity and potential for broad application, this innovative sensor technology heralds a new era in indoor air quality monitoring, empowering individuals and communities to safeguard their well-being.
