ABSTRACT
We present a low-cost Remote Laboratory platform developed to support the practices of the Vehicle Electronics course during the COVID-19 pandemic. The platform, which emerged as an emergency solution, has become a significant teaching resource. Although the platform was designed primarily for microcontroller (or FPGA) based practices, it could be extended to Analogue Electronics practices. From a hardware perspective, low-cost devices such as a Raspberry Pi, a camera or a old PC box have been used, while the software interface has been developed using Node-RED. © 2022 IEEE.
ABSTRACT
As the COVID-19 pandemic continues, there remains a need for fast, accurate and low-cost diagnostic tests to prevent outbreaks. We have developed an electrochemical capillary-flow driven immunoassay (eCaDI) capable of detecting SARS-CoV-2 nucleocapsid (N) protein in self-administered nasal samples at the point of care (POC). The low-cost device is made of polyester and adhesive films and provides sequential delivery of sample and reagents to a detection zone integrating a screen-printed carbon electrode (SPCE) modified with anti-N protein antibodies from a single addition of sample, automating the steps of an ELISA. The modified electrodes are highly sensitive and selective for COVID-19 N protein and were successfully applied to test clinical samples. The novelty of this work resides in the integration of sensitive electrochemical detection with pump-free capillary-flow assay, providing accuracy at the POC. Previously reported systems are slow and/or require multiple user steps reducing the utility for POC applications relative to the system reported here. © 2021 MicroTAS 2021 - 25th International Conference on Miniaturized Systems for Chemistry and Life Sciences.

ABSTRACT
Τhe rehabilitation process of sports injuries, movement and balance of the elderly with mobility problems as well people with injuries, is of key importance for the best possible recovery of proper functioning and mobility of the limbs of these individuals. In most cases, rehabilitation is provided in specialized rehabilitation centers, through services and recovery programs that are carried out for a specific period of time. During the patient's stay in the rehabilitation center, professional gait and balance analysis systems are used to assess his condition. These systems are usually too expensive, difficult to use, and can not be easily replaced by lower cost devices that provide the same quality and reliability. Furthermore, due to COVID-19 pandemic, the physical presence of a person during the execution of rehabilitation program has become prohibitive in many cases. Our solution offers an at-home rehabilitation exercises system using Virtual Reality with a human-alike Virtual Coach. The exercises for each patient are defined by doctors providing a personalized record tracking the rehabilitation progress. © 2021 IEEE
