This paper addresses the development of flow sensors optimised for heating, ventilating, and air conditioning systems. The sensors are based on the printed circuit board technology facilitating robust, flexible (in terms of layout), and cost-effective devices. Two approaches for measuring fluid quantities are investigated in this context and several sensor embodiments were investigated and fabricated. After experimental characterisation, measurement and simulation results were compared.

A research activity in the context of ambient assisted-living and Internet of Things applications is presented. A new assistance system with an integrated, multi-sensor, low-cost, autonomous, smart spoon device, denoted as Lab-on-Spoon, has been conceived. The goal is to provide assistance for unskilled or challenged consumers by sensory context in ingredients and cooking results. Successful liquid ingredient recognition and quality assessment, i.e., rotting and contamination, was achieved.
