Title
(EN) A WIRELESSLY POWERED FREQUENCY-SWEPT SPECTROSCOPY SENSOR
(FR) CAPTEUR DE SPECTROSCOPIE À BALAYAGE DE FRÉQUENCE ALIMENTÉ SANS FIL
Abstract
(EN)
Systems and methods in accordance with embodiments of the invention implement wirelessly powered frequency-swept spectroscopy sensors. One embodiment includes a first antenna configured to receive an incoming signal; an energy-harvesting circuit configured to produce DC energy; a power management unit; an on-chip signal source configured to use the incoming signal as a locking signal; and a second antenna configured to transmit back a signal locked to the frequency of the incoming signal. In a further embodiment, the wirelessly powered frequency-swept spectroscopy sensor includes a third antenna, where the third antenna is on-chip.

Selon certains modes de réalisation, la présente invention concerne des systèmes et des procédés qui mettent en œuvre des capteurs de spectroscopie à balayage de fréquence alimentés sans fil. Un mode de réalisation comprend une première antenne conçue pour recevoir un signal entrant ; un circuit de collecte d'énergie conçu pour produire de l'énergie CC ; une unité de gestion de puissance ; une source de signal sur puce conçue pour utiliser le signal entrant en tant que signal de verrouillage ; et une deuxième antenne conçue pour émettre un signal verrouillé à la fréquence du signal entrant. Dans un autre mode de réalisation, le capteur de spectroscopie à balayage de fréquence alimenté sans fil comprend une troisième antenne, la troisième antenne étant sur puce.
