Inhalt:

• Electronics Design for Energy Harvesting System Syllabus: This lecture will focus on the circuit topologies used with energy harvesters and pay special attention to power and energy budgets. It will consist of several parts: 1) Imperfections of passive and active components used with harvester circuits, component modelling including parasitics 2) Simple rectifier/harvester circuits, loss mechanisms present in these circuits, realistic views on achievable power and efficiency figures 3) Advanced rectifier/harvester circuits, differences between harvesting schemes for stationary processes (e.g. vibration) versus instationary processes (e.g. stepping, shock actuation) optimization of circuitry and minimization of losses, Advanced harvester topologies making use of resonant phenomena, discussion on timings and I/U transient behavior 4) System architectures including battery management and voltage conversion, State of Charge SoC derivation, power and energy budget calculations 5) Application examples of power needs by circuitry in wearables and medical electronics with wireless interfaces, schemes for energy management, benefits from duty cycles in wireless communication.
• Body Area Communications Syllabus: This lecture will introduce basic knowledge and application examples using body area communication. It mainly consists of five parts. (1) On-body transmission mechanism and characteristic, (2) In-body transmission mechanism and characteristics, (3) Transceiver design example, (4) Application to wireless robot control, and (5) Related electromagnetic compatibility (EMC) issues.
• Multiphysical Simulation Technique and Bio-safety Assessment Syllabus: This lecture explaines computational tehcniques for human exposure to electromagnetic field, icnluding resultant temperature rise. The relationship between exposure and product safety standards is discussed including the rationale from engineering viewpoint from extremely low frequencies to millimeter waves. Recent standardization related to emerging wireless communications system is also summarized.
