A rhythmic, sustained, stable potential oscillation was reproducibly observed for a lipid membrane supported by a micropore of a thin membrane tip micropipette. Amplitude and period of the oscillation voltage was controlled by changing the pore diameter. The relationship between oscillation period and pore diameter when the pore diameter was below 8 µm was different from that when the diameter was larger than 8 gm.
