The Future of Neuroscience: Flexible and Wireless Implantable Neural Electronics

Published in Advanced Science, 2021

This paper presents challenges in engineering and neuroscience in developing miniaturized and biointegrated alternatives, in the form of microelectrode probes. Progress in design and topology of neural implants has shifted the goal post toward highly specific recording and stimulation, targeting small groups of neurons and reducing the foreign body response with biomimetic design principles. Implantable device design recommendations, fabrication techniques, and clinical evaluation of the impact flexible, integrated probes will have on the treatment of neurological disorders are provided in this report.

Baseline Features Extraction from Microelectrode Array Recordings in an in vitro model of Acute Seizures using Digital Signal Processing for Electronic Implementation

Published in 2021 IEEE International Conference on Omni-Layer Intelligent Systems (COINS), 2019

Microelectrode arrays (MEA) arise as a promising technology enabling detection of local field potentials from multiple locations and permitting the acquisition of more information on brain network electrical activity than conventional electrophysiology techniques. However, whereas most of the electrophysiological studies addressing brain activity have focused on events/patterns analysis, no one has so far addressed the features that might be hidden within the signal baseline. In this paper, I performed an analysis of the Microelectrode Array Signal to study all the features and frequency content of this signal.

Flexible Wirelessly Powered Implantable Device

Published in 26th IEEE International Conference on Electronics, Circuits and Systems (ICECS), 2019

This paper presents a neural implant that is powered wirelessly using a flexible biocompatible antenna. We have applied a modular structure approach to the design of this device considering three modules of antenna, conditioner circuit and shank. The implant was fabricated using a flexible substrate of Polyimide and encapsulated by PDMS for chronic implantation. In addition, finite element method COMSOL Multiphysics simulation of mechanical forces acting on the implant and shank was carried out to validate a viable shank conformation-encapsulation combination that will safely work under operational stress with a satisfactory margin of safety.

A review of Quantum Dots methods and their applications in the field of Biotechnology

Published in Educational Innovation Project of University of Malaga Conference Days , 2016

The purpose of this communication is to make a bibliographic review of Quantum Dots methods and their applications in the field of Biotechnology. Quantum dots (QDs) are a novel class of inorganic fluorophores, which are gaining widespread recognition as a result of their exceptional photophysical properties.
