Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : This paper describes a CMOS interface for short-range wireless sensor networks (CMOS-SRWSN interface). The sensor interface is composed of a sensor readout, electronics for processing and control, a memory, a radio-frequency CMOS transceiver for operation in the 2.4-GHz industrial, scientific, and medical bands, and a planar antenna. The receiver has a sensitivity of -60 dBm and consumes 6.3 mW from a 1.8-V supply. The transmitter delivers an output power of 0 dBm with a power consumption of 11.2 mW. The application of the CMOS-SRWSN interface is in the automotive industry for the reduction of cables and to support the information, communication, and entertainment systems in cars.

Thermoelectric microconverter for energy harvesting systems / Carmo, Joao Paulo in IEEE transactions on industrial electronics, Vol. 57 N° 3 (Mars 2010) 

Public ISBD [article]  in IEEE transactions on industrial electronics > Vol. 57 N° 3 (Mars 2010) . - pp. 861 - 867 Titre : Thermoelectric microconverter for energy harvesting systems Type de document : texte imprimé Auteurs : Carmo, Joao Paulo, Auteur ; Goncalves, Luis Miguel, Auteur ; Correia, José Higino, Auteur Article en page(s) : pp. 861 - 867 Note générale : Génie élecrique Langues : Anglais (eng) Mots-clés : Energy  harvesting  Microgeneration  Renewable  energy  sources  Thermoelectric  energy  scavenging  systems Index. décimale : 621.38 Dispositifs électroniques. Tubes à électrons. Photocellules. Accélérateurs de particules. Tubes à rayons X Résumé : This paper presents a solution for energy microgeneration through energy harvesting by taking advantage of temperature differences that are converted into electrical energy using the Seebeck effect. A thermoelectric microconverter for energy scavenging systems that can supply low-power electronics was fabricated using thin films of bismuth and antimony tellurides. Thin films of n-type bismuth (Bi2Te3) and p-type antimony (Sb2Te3) tellurides were obtained by thermal coevaporation with thermoelectric figures of merit (ZT) at room temperature of 0.84 and 0.5 and power factors (PF × 10-3 [W · K-1 ·m-2]) of 4.87 and 2.81, respectively. The films were patterned by photolithography and wet-etching techniques. The goal for this thermoelectric microconverter is to supply individual electroencephalogram (EEG) modules composed by an electrode, processing electronics, and an antenna, where the power consumption ranges from hundredths of microwatts to a few milliwatts. Moreover, these wireless EEG modules allow patients to maintain their mobility while simultaneously having their electrical brain activity monitored.
