The activation device is configured to emit a wireless signal to activate the stimuli responsive actuator of the consumable capsule, and the consumable capsule is configured to release the active ingredient into an external environment based on the activation of the stimuli responsive actuator. ## Claims ### Claim 1 A consumable capsule having an outer surrounding sidewall, comprising: a signal receiving section comprising at least one coil configured to receive a wireless signal; a control section configured to condition the wireless signal received by the at least one coil into a trigger signal for the consumable capsule; a compartment section comprising at least one capsule compartment movably sealed by a stimuli responsive actuator, the compartment section being configured to activate the stimuli responsive actuator in response to the trigger signal from the control section to allow for release of an active ingredient contained in the at least one capsule compartment into an external environment wherein the stimuli responsive actuator extends around the entire circumference of the outer surrounding sidewall and activation of the stimuli responsive actuator causes the stimuli responsive actuator to change shape in at least a radial direction and a longitudinal direction. ### Claim 2 (depends on 1) The consumable capsule of claim 1, wherein the at least one stimuli responsive actuator comprises azobenzene incorporated in a liquid-crystalline elastomer. ### Claim 3 (depends on 1) The consumable capsule of claim 1, wherein the compartment section further comprises a light source configured to emit light based at least in part on the trigger signal, and wherein the stimuli responsive actuator is activated based at least in part on the emitted light. ### Claim 4 (depends on 1) The consumable capsule of claim 1, wherein the compartment section comprises at least two capsule compartments, the compartment section configured to simultaneously open the at least two capsule compartments. ### Claim 5 (depends on 1) The consumable capsule of claim 1, wherein the compartment section comprises a plurality of capsule compartments, the compartment section being configured to sequentially open each capsule compartment of the plurality of capsule compartments. ### Claim 6 (depends on 1) The consumable capsule of claim 1, wherein the control section comprises: at least one rectifying circuit for rectifying the wireless signal, the rectifying circuit comprising at least one light emitting diode (LED), and wherein the at least one LED is configured to activate the stimuli responsive actuator. ### Claim 7 A consumable capsule having an outer surrounding sidewall, comprising: a signal receiving section comprising at least one coil configured to receive a wireless signal; a control section configured to condition the wireless signal received by the at least one coil into a trigger signal for the consumable capsule; a compartment section comprising at least one capsule compartment movably sealed by a stimuli responsive actuator, the compartment section being configured to activate the stimuli responsive actuator in response to the trigger signal from the control section to allow for release of an active ingredient contained in the at least one capsule compartment into an external environment wherein the stimuli responsive actuator extends around the entire circumference of the outer surrounding sidewall and activation of the stimuli responsive actuator causes the stimuli responsive actuator to separate along a seam extending in a direction generally parallel to a longitudinal axis of the capsule. ### Claim 8 (depends on 7) The consumable capsule of claim 7, wherein the at least one stimuli responsive actuator comprises azobenzene incorporated in a liquid-crystalline elastomer. ### Claim 9 (depends on 7) The consumable capsule of claim 7, wherein the compartment section further comprises a light source configured to emit light based at least in part on the trigger signal, and wherein the stimuli responsive actuator is activated based at least in part on the emitted light. ### Claim 10 (depends on 7) The consumable capsule of claim 7, wherein the compartment section comprises at least two capsule compartments, the compartment section configured to simultaneously open the at least two capsule compartments. ### Claim 11 (depends on 7) The consumable capsule of claim 7, wherein the compartment section comprises a plurality of capsule compartments, the compartment section being configured to sequentially open each capsule compartment of the plurality of capsule compartments. ### Claim 12 (depends on 7) The consumable capsule of claim 7, wherein the control section comprises: at least one rectifying circuit for rectifying the wireless signal, the rectifying circuit comprising at least one light emitting diode (LED), and wherein the at least one LED is configured to activate the stimuli responsive actuator.
