Design considerations to move towards autonomously powered sensor systems

Content of the lecture:

The lecture will discuss the design issues, challenges and considerations for an autonomously powered wireless sensor node using energy harvesting. An example use case will be presented that takes the student through the process of designing a power system for a Wireless Sensor, from identification and framing of the technical challenge from the user requirements through to system design, component selection and power conversation strategies.

The lecture will be broken down into the following sections.

  • How the power challenge is one of the barriers to wide spread adoption of Sensor Networks
  • A systems approach to powering wireless Sensors
    • Framing the Challenge, developing a requirements specification
    • System Modelling,
    • Trade-Offs
    • Example Design Use Case
  • System Component Selection
    • Power Management the heart of the system
    • Energy Generation
    • Energy Storage
    • Power Consumption (Wireless Sensor)
  • System Power conservation Strategies
  • Some practical design considerations
  • Future Technologies and Direction
