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

5. Determination of thermal parameters and the optical gap of poly(3-butylthiophene) films by photopyroelectric spectroscopy

Author

Melo, W.L.B., Pawlicka, A., Sanches, R., Mascarenhas, S., and Faria, R.M.

Subjects
Pyroelectric detectors -- Usage, Optical films -- Research, Spectrum analysis -- Methods, Physics
Abstract

Photopyroelectric spectroscopy which involves a PVDF film as the pyroelectric detector is used in the determination of the thermal parameters and the optical gap of undoped poly(3-butylthiophene) films. The amplitude and the phase curves for different chopping frequencies enable the determination of the band gap energies.
