In this letter we introduce a new type of infrared sensor, based on thermocouple nanoantennas, which enables the energy detection and gathering in the mid-infrared region. The proposed detector combines the Seebeck effect, as a transduction mechanism, with the functionalities of the optical antennas for optical sensing. By using finite-element numerical simulations we evaluate the performance and...
Thermo-electrical nanoantennas have been proposed as an alternative option for conversion solar energy harvesting applications. In this work, the response of a spiral broadband antenna has been obtained from numerical and theoretical simulations perspectives. The results show that this device exhibits a responsivity of 20mV/W under 117W/cm2, for a single-frequency radiation. We discuss strategies...
A multiplexed low coherence tandem interferometric system coupled with a PMMA-PMTGA-PMMA polymer allows the measurement of the humidity of the air with an accuracy of 1.2% RH. This polymer shows rapid and complete reversibility as humidity is decreased and does not suffer from ageing.
