Thermal management is one of the key factors to keep lithium-ion cells in optimum electrical performance, under safe working conditions and into a reasonably low ageing process. This issue is becoming particularly relevant due to the heterogeneous heat generation along the cell.Cell working temperature is determined by ambient temperature, heat generation and evacuation capacity. Therefore, thermal...
Real time state of charge (SoC) and state of health (SoH) monitoring plays an essential role in electric vehicles, hybrid electric vehicles and generally in battery powered applications. Between these two state estimations, only the SoC has been studied rigorously until the current dates, while SoH or capacity estimation are much less referenced on the literature. Additionally, the SoC and the SoH...
Tactile sensors are applied to different areas like robotics, medicine or virtual reality. Many of these sensors are based on piezoresistive films that cover an array of electrodes. This approach is simple and cheap and seems to be able to fit the requirements of applications like manipulation with robotic hands or grippers. Local preprocessing is a must in these systems to reduce errors and interferences...
Magnetic resonance imaging (MRI) systems are widely used to gather noninvasively images of the interior of the human body. This paper suggests that an MRI system can be seen beyond being just a tool for imaging purpose but one that can propel and guide special microdevices in the human body to perform specific medical tasks. More specifically, an MRI system can potentially be used to image the region...
