Abstract: A biometric apparatus includes a light source, an image sensor, a control circuit, and a signal processing circuit. The control circuit causes a light source to repeatedly emit a light pulse radiated onto a target part including a head of a target, causes an image sensor to receive a reflected light pulse which is caused as the light pulse is radiated onto the target part, causes the image sensor to output first image data indicating appearance of a face of the target, and causes the image sensor to output second image data according to distribution of an amount of light of at least one of components of the reflected light pulse. The signal processing circuit generates data indicating a state of the target based on a temporal change in the first image data and a temporal change in the second image data and outputs the data.

Abstract: A target substance detection method includes forming a complex by causing a target substance and a dielectric particle to bind to each other, the dielectric particle being modified with a substance (for example, an antibody) having a property of specifically binding to the target substance; subjecting a bound particle and an unbound particle to dielectrophoresis in a liquid, the bound particle being the dielectric particle constituting the complex, the unbound particle being a dielectric particle not constituting the complex; and detecting the target substance in the complex, based on a difference in motion between the bound particle and the unbound particle caused by the dielectrophoresis.
