Abstract

The EU project SENSIndoor aims at the development of novel nanotechnology based intelligent sensor systems for selective monitoring of Volatile Organic Compounds (VOC) for demand controlled ventilation in indoor environments. Target gases are benzene, naphthalene and formaldehyde, as these VOCs are highly health relevant and occur in many indoor environments, thus making their monitoring a high priority for safe and healthy buildings. Relevant concentrations according to recommended values given by the WHO are in the low ppb range with benzene requiring the highest sensitivity to achieve a target concentration below 1 ppb. The SENSIndoor project makes use of two novel approaches to achieve this challenging goal: highly porous and well-controlled nano-scaled gas-sensitive layers deposited by Pulsed Laser Deposition (PLD) as well as selective pre-concentration using Metal-Organic Frameworks integrated on micro hotplates.
