Multiple physiological signals sensing chip and the multiple physiological signals sensing method thereof

A multiple physiological signals sensing chip, comprising:

• a substrate, comprising a contact surface touched by a finger of a user;
• at least one first light-emitting diode, used to emit red light to the finger;
• at least one second light-emitting diode, used to emit infrared light to the finger;
• a sensing array, sensing the red light or the infrared light reflected or refracted from the finger to obtain a plurality of first physiological sensing signals according to a first sensing period or sensing the red light and the infrared light reflected or refracted from the finger to obtain a plurality of second physiological sensing signals according to a second sensing period, wherein the first sensing period is shorter than the second sensing period;
• and
• a processing unit, connected to the at least one first light-emitting diode, the at least one second light-emitting diode and the sensing array, wherein the processing unit operates the at least one first light-emitting diode, the at least one second light-emitting diode and the sensing array according to the first sensing period and the second sensing period;
• and
• wherein the processing unit processes the first physiological sensing signals to obtain spatial information corresponding to the finger and processes the second physiological sensing signals to obtain energy information corresponding to the finger.
