1. A biomedical sensor device, comprising:
- a light source, configured for emitting infrared radiation;
a probe array, for contacting to a user'"'"'s skin and for detecting an electric wave signal from the skin, and comprising a substrate and a plurality of probes mounted on the substrate, wherein the substrate and the probes are non-opaque whereby the infrared radiation transmits through the probe array into the skin, wherein each of the probes comprises;
a tip portion;
a first stalk portion, comprising a top thereof connected to the tip portion, wherein a cross-sectional area of the top is larger than that of a bottom of the first stalk portion; and
a second stalk portion comprising a bottom thereof connected to the substrate, and wherein the cross-sectional area of a top of the second stalk portion is smaller than that of the bottom of the second stalk portion; and
a photo detector, configured for detecting an infrared signal by measuring the infrared radiation absorption by the skin.

Abstract
A biomedical sensor device includes a light source, a probe array, and a photo detector. The light source is configured for emitting infrared radiation. The probe array is contacted to a user'"'"'s skin to detect an electric wave signal transmitted through the probe array from the skin. The probe array includes a substrate and a plurality of probes mounted on the substrate, wherein the substrate and the probes are non-opaque so that the infrared radiation may be transmitted through the probe array into the skin. The photo detector is configured to detect an infrared signal by measuring the infrared radiation absorption by the skin.
