ABSTRACT:
A biological oscillating device comprises a lipid-impregnated membrane which is disposed in an electrolyte solution and in which is buried an ion channel having a selectivity opposite to that of the lipid-impregnated membrane, and an electrode provided for transmitting a membrane potential of the lipid-impregnated membrane in the form of an electrical signal. When a membrane potential is caused across the lipid-impregnated membrane by the application of an electric current via an eletrode, or by the activation of the ion pump, an ion pump, an ion channel opens once the magnitude of the membrane potential reaches the active potential of the ion channel, whereby the membrane potential is accordingly eliminated. Upon the elimination of the membrane potential, the ion channel is closed to allow the membrane potential to be again raised. Then, once reaching the active potential of the ion channel, the ion channel reopens so that the membrane potential is correspondingly eliminated. Through the repetition of such procedures, an oscillating electrical signal can be generated.
