In previous years, we have worked with polymer polyvinyl fluoride (PVDF) nanostructures to improve their piezoelectric capacity and add other properties such as ferroelectricity and ferromagnetism by incorporating Iron Oxide (Fe3O4) and Zinc Oxide (ZnO) nanoparticles into the solutions. To summarize, there have been numerous configurations of assembled and tested experiments. Our next thought was to build an automated controlled electrospinning system, with a plan to carry out the experiments with precision, automation, and remote control. This article shows the technical details and images of the design, including the sketches, electronics of the system and how remote access was achieved, using sensors and printed circuit boards. Finally, we show the results of the tests along with images of the nanofibers taken with a Scanning Electron Microscope (SEM) and how it has assisted us in improving the quality of our experiments.

Analyzing the acceleration signals of buildings during a seismic event helps us to identify the vibrational intensity of the structure. This research proposes a methodology to recognize the level of the vibrational intensity of a building during an earthquake with a few seconds before its maximum vibration using the P wave response. The proposed methodology is based on the Discrete Fourier Transform (DFT) and Support Vector Machine (SVM). This methodology results in an alert level that is classified according to its vibrational intensity (low, moderate and high). Each building could have different alerts in the event of an earthquake since may have different natural frequencies. A prototype implemented with a Raspberry Pi V4 B embedded system, two acceleration sensors called MPU6050 based on MEMS and a Wi-Fi antenna, mainly, is used. Also, filters were used to attenuate noise. The STA/LTA algorithm is used to compare the detection time. The results show that it is convenient to use the methodology for two main reasons. Firstly, this uses one tenth of the samples needed in the STA/LTA algorithm for detection and with the same efficiency. Secondly, the classification of the alert level in the building has a correlation greater than 0.8 with the PGA of the seismic signal that occurred in its structure.

The use of hexagonal grids of pixels to represent digital images is a topic that has been studied for decades; however, despite its advantages there is relatively little work done on the subject. On the other hand, for the compression of images with rectangular grids, where there is far more research, the use of the wavelet transform is a strategy that allows high levels of performance to be achieved; two examples of image compression systems based on wavelets are the JPEG2000 standard and the IW44 algorithm used by DjVu, both currently still in use. In this work we are interested in evaluating the feasibility of a hexagonal grid image compression system using wavelets for implementation on a configurable sensor made of pixels on a hexagonal grid previously developed by our group. In order to do this, theoretical and implementation aspects of image compression with wavelets on hexagonal grids of pixels are studied first. A complete hexagonal image compression system is then implemented using Haar like wavelets and an adaptation of the coding algorithm for rectangular images SPIHT. To evaluate the performance of the proposed system, a comparison is made with its rectangular analogous version by testing with multiple images. Finally, a simple test is carried out on the configurable sensor that shows the it is possible to directly read the decomposition coefficients instead of reading pixel by pixel.

This paper aims to provide an automation system for remote monitoring and control of strategically located actuators in a prototype hydroponic greenhouse using voice command recognition. The concept combines the use of the Rosenberg Model and the Fourier Transform for linear signal processing in discrete time with applied mathematical methods for voice signal filtering. The mathematical model required for the analysis and capture of the speech spectrum was developed in MATLAB. In addition, a system with temperature, humidity, heat index, illumination and level sensors is incorporated to send information to the user through an Arduino Mega with a Bluetooth HC-06 module as a communication protocol for the control and monitoring of the environmental parameters that indicate in the greenhouse. The article concludes by proposing a development of a mobile application for communication between the user and the prototype with the possibility of generating records for the evolution of environmental parameters over time.

The LabOSat collaboration aims to increase the Technology Readiness Level of electronic devices and components for space-borne applications in Low Earth Orbits. Since 2014, the collaboration has tested different electronic components in space environments using different versions of its flagship testing platform: LabOSat-01. Some of the electronic components tested in the past include resistive switching memories and dosimeters based on field-effect transistors. A daughter board was developed for LabOSat-01, which was used to characterize four ONSEMI MicroFC-60035-SMT Silicon Photomultipliers in DC mode. Each Silicon Photomultiplier was enclosed in a light-tight aluminum housing along with an LED to test it under controlled illumination.In this Proceeding, we report the results obtained after 2 and a half years (958 days) of measurements of Silicon Photomultiplier performance in Low Earth Orbit. The temperature range of the electronics and sensors was −7 °C to 4 °C. The DC-DC boost converters used to bias the Silicon Photomultipliers remained operational at the set bias voltage of 29.1 V. An increase of expected Silicon Photomultiplier current under various LED illuminations was observed and these values increased with mission time. Several hypotheses are under evaluation, like gradual damage to the electronics, to the light-tight housings, or both.

Microwave kinetic inductance detectors (MKID) are a growing technology of cryogenic detectors and have a great potential in radio-astronomy and cosmic microwave background (CMB) characterization. A review of the general readout performance requirements for experiments requiring the multiplexing of large arrays (~10.000 pixels) of such cryogenic detectors is presented. The focus is on the crest factor optimization process for proper excitation and readout of these large arrays of detectors. It is shown an algorithm to optimize the phase generation of the carriers to obtain a low crest factor, favoring the dynamic range usage of the electronic chain.

A microwave kinetic inductance detector (MKID) is a superconducting pair-breaking detector used for astronomical observations in the sub-millimeter through visible range. Radiation is detected as a phase and amplitude signal proportional to the frequency shift of the device. In the case of arrays of MKIDs, the read-out is performed using the frequency division multiplexing technique. However, there is currently no commercial system or low-cost standard electronics available for this task. In this work, we take the first steps towards developing a low-cost readout system for MKIDs based on the Red Pitaya board. We have developed a firmware for the efficient generation of probe tones, and show figures of merit characterizing the performance of the readout in a hardware prototype. The design is flexible, letting us to adapt it to new frequencies and amplitudes requirements of the MKID arrays.

In this work, a hardware implementation of a distributed Battery Management System was carried out. This hardware is formed by a current and voltage monitor, a SD card, and a microcontroller, in which a remaining discharge time prediction algorithm based on an extended Kalman filter was programmed. The Kalman filter estimates the state of charge and another dynamic variable that allow to use the Lambert function to find the remaining discharge time from the end-of-discharge voltage value. By using a commercial battery, the performance of the algorithm was evaluated at different discharge rates. The experimental results show that the proposal is suitable to be implemented on a embedded system or integrated into an application specific integrated circuit to be coupled in a battery pack.

In recent years, it is possible to observe a quickly adoption and daily use of wearable electronic devices such as smart watches and bracelets. Such devices have dedicated systems for monitoring biological signals, such as heartbeat and blood oxidation, and some of these devices already have the ability to provide measurements of electrocardiogram (ECG) and blood pressure signals. Additionally, these devices also feature wireless connection via Bluetooth orWi-Fi communication protocols. Both modern instrumentation and communication systems require the digitization of analog signals by means of analog-to-digital convertes (ADCs) for further digital signal processing. This work presents the design of a Successive Approximation Register (SAR) ADC for low voltage applications with 10 bits and 5 kSPS in asynchronous operating mode. The ADC is designed in 180-nm CMOS technology and operates at a nominal supply voltage of 0.5 V. Schematic-level simulations indicate that the ADC reaches a signal-to-noise-to-distortion (SNDR) ratio of 61.36 dB, leading to an effective number of bits (ENOB) of 9.90 bits. The spurious-free dynamic range (SFDR) is 73.19 dB, and the total power consumption of the ADC is 1.43 μW.

This article explores for the first time the feasibility of an open source high performance amplifier for IEEE 802.3an 10Gbase-T transceivers. The design is based on the 130nm Skywater PDK and was developed using only free open source tools. Post-layout simulations show that the amplifier is compatible with the 10Gbase-T specification, reaching a total harmonic distortion (THD) of −51.9dB and a signal to noise ratio (SNR) of 60dB in typical corner. Finally, the open source design aim used here makes the HPA reproducible, modifiable and be directly usable as a sub-circuit in integrated circuit design projects.
