Introduction Thermal systems are difficult to model because of the complexity of the modes of heat transfer: conduction, convection, and radiation. Thermal conductivity can vary depending on the temperature and direction (such as with some crystals). Convection needs to consider fluid dynamics, which can be free or forced, laminar or turbulent. Thermal radiation is electromagnetic …

Introduction Properly optimizing energy consumption of battery powered microcontrollers (MCUs) is fundamental to extend their battery life. Questions like when it is better to keep the device idling and when to enter light- or deep-sleep cannot be answered without measuring the power consumption during those sleep modes and the time and energy overhead required to …
Introduction A Peltier device is a solid-state heat pump that transfers heat from one side to the other. This heat transfer simultaneously reduces the temperature of one side of the device and increases it on the other side, generating in this way a temperature gradient across the sides of the device. Peltier cooling is not …
Introduction DC-DC converters are devices that convert a source at one DC voltage into another. They can be classified in many ways, such as between linear and switching, between step-up and step-down, based on their topology, and so on. Depending on the application one may prioritize different figures of merit. For instance, for IoT applications …
