Gastric electrical stimulation has shown positive effects on weight reduction and on various gastric motility disorders. This stimulation leads to earlier satiety thus decreasing food consumption significantly. For long term effective function some control of implant activity is necessary, for which gastric volume and movements have to be sensed. For this purpose we have chosen mutual induction principle between small implantable coils. Sensors have to fulfill many requirements including biocompatibility, mechanical and chemical durability; and minimum power consumption. First successful in-vivo experiments were held with simple configuration of two implantable coils and an external electronics box.
