This study, conducted in the north of Portugal, is the result of a group of nurses' intent to develop a closer and meaningful person-centered care for patients with diabetes, empowering them with skills to better manage their therapeutic regimen. Through a participatory action research process, the group of nurses involved in this study, reflected on the current healthcare enabling them an in-depth analysis of the best scientific evidence, aiming to design context tailored solutions, which would contribute to patients' empowerment. Through a longitudinal study developed over several stages, the nurses outlined the educational programme Living in harmony with diabetes, which was applied to 85 patients with diabetes mellitus type 2. The programme had a positive impact on the psychosocial variables, in self-care behaviour and in the metabolic control, helping patients to better cope with their disease and have greater control over their health condition. Throughout the process of participatory action research, the nurses were able to increase their self-efficacy and empowerment on person-centered care implementation.

This paper details a power solution for smart grid applications to replace batteries by harvesting the electromagnetic energy from a current-carrying wire. A MEMS piezoelectromagnetic energy harvester has been fabricated using PZT screen-printing technology with a centrally-supported meandering geometry. The energy harvesting device employs a symmetric geometry to increase its power output by reducing the effects of the torsional modes and the resultant overall strain nodes in the system subsequently reduce the complexities for the electrode fabrication. The unit is modelled using COMSOL to determine mode shapes and frequency response functions. A 12.7 mm by 14.7 mm unit is fabricated by screen-printing 75 μm-thick PZT on a stainless steel substrate and then experimentally tested to validate the FEA results. Experimentally, the harvester is shown to produce 9 μW from a wire carrying 7 A while operating at a distance of 6.5 mm from the wire. The design of the current work results in a greater normalized power density than other MEMS based piezoelectromagnetic devices and shows great potential relative to larger devices that use bulk or thin film piezoelectrics.

Growing interest in improving the energy consumption efficiency in residential and commercial buildings has led to the emergence of intelligent energy management systems. This growing technology allows the transformation of the outdated electric distribution network within buildings to a smart and intelligent system. A major challenge in the development of such infrastructure is the need for low cost, integrated, self-contained, and non-invasive wireless sensor nodes. While an electric meter provides the utility company with information regarding the total energy consumption, no information is provided to the consumers regarding the energy consumed by individual appliances. Such visibility can provide consumers with the ability to better control and manage their energy usage leading to a reduced overall energy consumption.This work explores the design and development of a self-contained and non-invasive integrated system intended for real-time electricity monitoring within residential and commercial buildings. The proposed system includes an Energy Harvester, an electric current sensor, a Micro-controller Unit, and a wireless communication device. The proposed system is self-powered and non-invasive, which offers a promising solution in providing real time information regarding the energy distribution within buildings.The design featured in this work provides an innovative approach in the development of a customized interface circuitry that is designed to collect and regulate the energy from the Energy Harvester.The entire sensor node will operate under a power budget in the range of microwatts collected by the Energy
