Gibbs Free Energy Assisted Passivation Layers
(Spie-Int Soc Optical Engineering, 2016)
Reduction of surface leakage is a major challenge in most photodetectors that requires the elimination of surface oxides on etched mesas during passivation. Engineering the passivation requires close attention to chemical ...
Silent Enhancement of Sers Signa without Increasing Hot Spot Intensities
(Walter De Gruyter Gmbh, 2018)
Plasmonic nanostructures enhance nonlinear response, such as surface enhanced Raman scattering (SERS), by localizing the incident field into hot spots. The localized hot spot field can be enhanced even further when linear ...
A Robust System For Counting People Using An Infrared Sensor And A Camera
In this paper, a multi-modal solution to the people counting problem in a given area is described. The multi-modal system consists of a differential pyro-electric infrared (PIR) sensor and a camera. Faces in the surveillance ...
Contact-Free Measurement Of Respiratory Rate Using Infrared And Vibration Sensors
(Elsevier Science Bv, 2015)
Respiratory rate is an essential parameter in many practical applications such as apnea detection, patient monitoring, and elderly people monitoring. In this paper, we describe a novel method and a contact-free multi-modal ...
