Abstract

A device according to an embodiment includes: a simulated skin portion being located near a photoelectric pulse wave sensor to simulate a blood flow of the skin; a reflectance changing unit located on an opposite side of the simulated skin portion to the photoelectric pulse wave sensor, the reflectance changing unit changing, in time series, reflectance of light emitted from the light-emitting unit of the photoelectric pulse wave sensor and passing through the simulated skin portion; a reflectance change control unit that transmits a reflectance control signal to the reflectance changing unit to control changes in reflectance of the reflectance changing unit; and a synchronization signal output unit that outputs a signal in sync with the reflectance control signal to an external device.
