Nowadays, the semiconductor industry is reaching an impasse due to the scaling-down process according to Moore’s Law, initiated back in 1960s, for the Metal-Oxide-Technology in use. To overcome such issue, the semiconductor industry started to foresee novel materials that allow the development of nanodevices with a broad variety of characteristics such as high switching speed, low power consumption, robust, among others; that can overcome the inherent issues for Silicon. A few “exotic materials” appear such as Graphene, MoS2, BN-h, among others. However, the time for the novel technology to be mature is a few decades in the future. To allow the “exotic materials” to mature, the semiconductor industry requires of novel nano-structures that can overcome a few of the issues that Silicon-based technology is facing today. A key alternative is based on hybrid structures. Hybrid structures encompass two dissimilar technologies nano-electromechanical systems with the well known Metal-Oxide-Technology. The hybrid nano-structure provides a broad variety of options to be used in such as transistors, memories and sensors. These hybrid devices can give enough time for the technology based on “exotic materials” to be reliable as Silicon based is.

In this work, the normalized interference pattern produced by a coherence interferometer system was represented as a complex function. The Laplace transform was applied for the transformation. Poles and zeros were determined from this complex function, and then, its pole-zero map and its Bode diagram were proposed. Both graphical representations were implemented numerically. From our numerical results, pole location and zero location depend on the optical path difference (OPD), while the Bode diagram gives us information about the OPD parameter. Based on the results obtained from the graphical representations, the coherence interferometer systems, the low-coherence interferometer systems, the interferometric sensing systems, and the fiber optic sensors can be analyze on the complex s-plane.

Facial palsy is one of the most frequent mononeuropathies expressed in muscular weakness. The condition is produced by lesions in the seventh cranial nerve that causes esthetic, functional, and psychosocial alterations. The disorder has a qualitative diagnosis, and as a consequence, it does hinder the disease timely monitoring. As time is a key factor for the patient’s recovery, we developed a system capable to quantify the condition and/or damage in the seventh cranial nerve. It allows us to provide the best treatment available that offers the best response to each patient. To know the seventh cranial nerve state is possible due to the connections between whole muscular system and neurons. The system quantifies the muscles activity and displays the differential information of both hemifaces. Our proposal features a mask in which an array of sensors is placed across the frontal, zygomatic minor, risorio, zygomatic major muscles of each hemiface. The data collected are analyzed and displayed in a user-friendly interface.
