Abstract
A biological feature-sensing device for acquiring biological feature information by sensing a biological feature is provided. The biological feature-sensing device includes a capacitive touch panel and a control circuit. The capacitive touch panel includes signal transmitting lines and signal receiving lines. A first pitch of the signal transmitting lines or a second pitch of the signal receiving lines is greater than or equal to a minimum on-center spacing of the biological feature. The control circuit receives first and second voltage signals through two sets of signal receiving lines in response to first and second charge/discharge signals transmitted through two sets of signal transmitting lines, and generates a characteristic value according to the first and second voltage signals. Many characteristic values corresponding to different combinations of the signal transmitting lines and signal receiving lines are generated accordingly to form a characteristic value matrix representing the biological feature information.
