    摘要: The invention relates to an electronic pill (102) for delivery of a medication (104) inside a mammal. The electronic pill (102) comprises a reservoir (106) for releasing the medication (104) in response to a predefined level of pressure. Furthermore a primary elastic element (108) is comprised for applying said predefined level of pressure to the reservoir (106) via a piston (110) upon release from the piston (110) of its constrained position. The piston (110) in its turn, when in constrained position, induces a predefined level of stress in the primary elastic element (108) by accordingly deforming it. The electronic pill (102) comprises a mechanism (114) for changing, upon actuation, from a constraining configuration in which the piston (110) is maintained at its constrained position to a releasing configuration in which the piston (110) is released. The mechanism (112) limits the displacement of the piston (110) during changing between said configurations to a level which is substantially smaller than the deformation introduced in the primary elastic element (108).
