masterThesisResumen:
En este proyecto de investigación se presenta el desarrollo de un sistema seguro para el monitoreo de variables ambientales. Para realizar este sistema primero se elaboró un estado del arte para conocer las diversas vulnerabilidades presentes en las redes de sensores inalámbricos, seguidamente se desarrolló una red de sensores para monitorizar la temperatura utilizando radios XBEE. Los sensores fueron configurados para que las transmisiones estén cifradas utilizando AES. La información proveniente de los sensores es registrada, cifrada y transmitida hacia un servidor remoto utilizando una conexión segura TLS por un software desarrollado en node.js. La información enviada por los sensores es visualizada en un aplicativo web desarrollado en php. Para la validación de su funcionamiento se realizaron pruebas de monitoreo de red utilizando la plataforma zigbee MC1322x y el analizador de paquetes wireshark, donde se comprobó que la transmisión es cifrada desde el nodo sensor hasta el servidor destino.
Descripción:
This research project presents the development of a safe system for the monitoring of environmental variables. In order to perform this system, a state of the art was elaborated to know the various vulnerabilities present in the networks of wireless sensors, followed by the development of a network of sensors to monitor the temperature using XBEE radios. The sensors were configured so that the transmissions are encrypted using AES, the information from the sensors is recorded, encrypted and transmitted to a remote server using a secure TLS connection by software developed in node.js. The information sent by the sensors is displayed in a web application developed in php. For the validation of its operation, network monitoring tests were performed using the MC1322x zigbee platform and the wireshark sniffer, where it was verified that the transmission is encrypted from the sensor node to the destination server.

Viscoelastic Effects on the Response of Electroelastic Materials
Díaz-Calleja, Ricardo; Ginestar, Damian; Compan Moreno, Vicente; Llovera-Segovia, Pedro; Burgos-Simon, Clara; Cortes, Juan Carlos; Quijano, Alfredo; Díaz-Boils, Joaquin (Polymers, 2021)Electroelastic materials, as for example, 3M VHB 4910, are attracting attention as actuators or generators in some developments and applications. This is due to their capacity of being deformed when submitted to an electric ... -
