Claim:
1. An electronic pill for delivery of a medication inside a mammal, comprising: a reservoir configured for releasing the medication in response to application of a predefined level of pressure on the reservoir; a piston configured to act on the reservoir and movable between a constrained position and a release position spaced from the constrained position; a primary elastic element for applying said predefined level of pressure to the reservoir via the piston upon release of the piston from its constrained position, wherein the piston, in the constrained position, deforms the primary elastic element to induce a predefined level of stress in the primary elastic element; and a mechanism movable relative to the piston and the primary elastic element between a constraining configuration arranged to maintain the piston in its constrained position and a releasing configuration in which the piston is free to move to the release position; an actuator having a threaded shaft; and a threaded nut engaging the threaded shaft and acting on the mechanism, the threaded nut being movable, by the actuator, along a longitudinal axis of the pill between a first position and a second position, the second position being spaced from the first position, wherein, in the first position, the threaded nut retains the mechanism in the constraining configuration and, in the second position, the threaded nut causes the mechanism to move to the releasing configuration.
