- Comparing Competency Assessment in Electronics Engineering Education with and without Industry Training Partner by Challenge-Based Learning Oriented to Sustainable Development Goals(MDPI, 2021-09-27) Gonzalez Peña, Omar Israel; Ávila Ortega, Alfonso; Dieck Assad, Graciano; GONZALEZ PENA, OMAR ISRAEL; 162547; Instituto Tecnológico y de Estudios Superiores de MonterreyThis study assessed the “creation of technological solutions for electronic devices” competencies evaluation when faculty–industry liaison is available. This experience at Tecnológico de Monterrey (TEC) was developed with challenge-based learning provided by the automotive electronics industry addressing subjects oriented toward some objectives of the Sustainable Development Goals (SDGs). The Electronics Engineering faculty and project engineers from automotive electronics and instrumentation companies promote design competencies in college students. This study analyzed the competency performance and outcome results of students who took applied electronics courses for the undergraduate level under the “i-Semester with industrial partner” for one semester and compared results with students that took the course under the traditional program. The competence evaluation was classified into three preliminary domain levels: 1 or low-level, 2 or medium-level, and 3 or high-level. Students were exposed to the conceptual, procedural, and attitudinal contents applied to solve the challenge assigned by the industrial partner. Students with an industrial partner showed a higher engagement, and they were more motivated in learning the subject, compared to students having classes in the traditional way. This study showed that in developing the competency “create technological solutions for electronic devices”, 55 students with an industrial partner obtained higher domain levels than 61 students with the traditional course.
- Electrochemical Instrumentation of an Embedded Potentiostat System (EPS) for a Programmable-System-On-a-Chip(MDPI, 2018-12-18) Gonzalez Peña, Omar Israel; Muñoz Martínez, Adrián Iván; Colomer Farrarons, Jordi; Rodríguez Delgado, José Manuel; Ávila Ortega, Alfonso; Dieck Assad, Graciano; GONZALEZ PENA, OMAR ISRAEL; 162547; Instituto Tecnológico y de Estudios Superiores de MonterreyUnder the main features required on portable devices in electrochemical instrumentation is to have a small size, low power consumption, economically affordable and precision in the measurements. This paper describes the development of a programmable Embedded Potentiostat System (EPS) capable of performing electrochemical sensing over system-on-a-chip platforms. Furthermore, the study explains a circuit design and develops some validation of the entire system. The hardware validation is performed by electrochemical experiments such as Double Step Chronoamperometry (DSC), Linear Sweep Voltammetry (LSV) and Cyclic Voltammetry (CV); moreover, a comparison of the experimental signals between a commercial potentiostat and the EPS was done by analysis of errors on the response signal. Results illustrate that the EPS is capable of handling currents in the range of absolute values of 86.44 to 3000 nA and having control voltages in the range of ±2 V. The device can support from 50 to 2000 samples per second. The EPS capabilities were compared with other compact potentiostats. The programmable EPS is an original approach which hugely reduces the hardware complexity and leads the way to create new applications for Point-of-Care or industrial developments with a reusable full electronics module.
