Electromagnetic fields :

• MEMS:
  actuators, Piezo, microfluidics, sensor
  
  
• Induction heating:
  transmitted power, circulation of induced currents

Electricity:

• Electrical insulator: minimization of risk of electrical breakdown risk with high-voltage cables
  
  
• Fuel cell: optimisation of gas channels and materials
  
  
• High-tension cable:
  -) mutual impedance between cables,
  -) thermal heating by Joule effect, optimisation of the fabrication processes
