    Sammanfattning : Energy Harvesting, also known as power harvesting or ambient power, is the process of obtaining small amounts of power from secondary sources, such as vibrations, light, temperature variations and even radio-frequency emissions. These systems have been uncommon in personal and wearable electronics in the past, however they are slowly gaining traction. LÄS MER

  7. 5. A General Purpose Analog Circuit to Accumulate Data From Resistive Sensors

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Karl Höjlund; Alan Alhallak; [2022]
    Nyckelord :Data acquisition; Wheatstone bridge; Analog conditioning; Digital potentiometer;

    Sammanfattning : Minimizing the need to physically adjust hardware platforms used for sensor measurements during the construction phase of an electric vehicle can be beneficial. Since different sensors have different measuring ranges a hardware platform used for a specific sensor might not work for another one, without physically tampering with it. LÄS MER
