Abstract

Smart home is expected to offer various intelligent services by recognizing residents along with their life style and feelings. One of the key issues for realizing the smart home is how to detect the locations of residents. Currently, the research effort is focused on two approaches: terminal-based and non-terminal-based methods. The terminal-based method employs a type of device that should be carried by the resident while the non-terminal-based method requires no such device. This paper presents a novel non-terminal-based approach using an array of pyroelectric infrared sensors (PIR sensors) that can detect residents. The feasibility of the system is evaluated experimentally on a test bed Index Terms--smart home, location-based service, pyroelectric infrared sensor (PIR sensor), location-recognition algorithm

Abstract

Doping of the polymer matrix material led to a drastic improvement in the coupling of the pyroelectric activity of the ferroelectric particles to the electrodes of composite films. Results suggest the usefulness of the doped composites for application in pyroelectric sensors.
