Patent ID: 8722228

Claim:
An apparatus comprising: a food product; a first battery attached to the food product in an inactive state, the first battery comprising: a first food-grade anode; a first food-grade cathode; and a first food-grade dry electrolyte configured to be activated by saliva to electrically connect the first food-grade anode and the first food-grade cathode to generate an electrical current, wherein a topology of the first food-grade anode is selected based on a dissolution rate of the first food-grade anode, wherein a topology of the first food-grade cathode is selected based on a dissolution rate of the first food-grade cathode, wherein a surface area of the topology of the first food-grade anode on the food product and a surface area of the topology of the first food-grade cathode on the food product are different, and wherein the rate of activation of the first battery is based on the topology of the first food-grade anode and on the topology of the first food-grade cathode; and a second battery attached to the food product in an inactive state, the second battery comprising: a second food-grade anode; a second food-grade cathode; and a second food-grade dry electrolyte configured to be activated by saliva to electrically connect the second food-grade anode and the second food-grade cathode to generate an additional electrical current, wherein the first battery is active for a first length of time and the second battery is active for a second length of time, and wherein the first length of time is different than the second length of time.
