Multifunctional probe and detection method thereof

A multifunctional probe, comprising:

• a hand-held housing;
• a signal detector, flexibly disposed on the hand-held housing;
• an array probe, disposed at one end of the hand-held housing and electrically coupled to the signal detector, wherein a first contact time of the signal detector in contact with a target at least partially overlaps with a second contact time of the array probe in contact with the target, and the signal detector and the array probe are configured to generate a first electronic signal;
• a multiplexer, electrically coupled to the array probe and the signal detector, wherein the multiplexer is configured to at least receive and transmit the first electronic signal;
• a switching circuit, electrically coupled to the multiplexer, wherein the switching circuit is configured to switch the multifunctional probe to a transmitting mode or a receiving mode and at least transmit and receive a second electronic signal;
• and
• a transmitting circuit, electrically coupled to the switching circuit, wherein the switching circuit receives a transmitting signal generated by the transmitting circuit when the switching circuit is in the transmitting mode, so that the signal detector and the array probe generate an ultrasonic signal;
• wherein the signal detector is configured to transmit a signal to the target and the array probe is configured to receive a signal from the target at the same time by partially overlapping the first contact time with the second contact time.
