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