Biological Information Sensing Device

A biological information sensing device comprising:

• an encapsulation layer including a sensing section configured to surround a to-be-tested object;
• a detection element disposed in the sensing section of the encapsulation layer, wherein the detection element includes a plurality of electrodes parallel to and spaced from each other and forming a left group of comb-shaped electrodes and a right group of comb-shaped electrodes alternatingly disposed with respect to the left group of comb-shaped electrodes, such that two adjacent electrodes are offset to left or offset to right, and projections of portions of the two adjacent electrodes overlap, and wherein two signal lines are respectively located on a left side and a right side of the plurality of electrodes, such that one of the two signal lines on the left side is electrically connected to electrodes offset to the left, and the other of the two signal lines on the right side is electrically connected to the electrodes offset to the right;
• and
• a signal transmission element disposed on a side of the encapsulation layer opposite to the sensing section, wherein the signal transmission element includes at least one coil and two transmission lines electrically connected to the at least one coil, and wherein the two transmission lines are electrically connected to the two signal lines.
