Abstract
An information processing system includes first and second electrodes for measuring cardiac potential, a pulse wave sensor that is disposed closer to the first electrode than to the second electrode and that measures a pulse wave, a buffer that amplifies a signal acquired by the first electrode, an interconnect wire that electrically connects the first electrode to a terminal of the buffer, a shield that shields the first electrode and the interconnect wire, and a shield potential generator that includes a first buffer circuit and a second buffer circuit having a larger drive current than the first buffer circuit and that starts applying, to the shield, a first generation signal generated by the first buffer circuit based on the acquired signal before a predetermined time point when the pulse wave is measured and starts applying a second generation signal generated by the second buffer circuit at the predetermined time point.
