  • Publication number: 20250134468
    Abstract: A signal sensing device includes a signal amplifying structure to amplify the strength of the measured signal. The signal sensing device includes a body, a signal sensing element, and a signal amplifying portion. The signal sensing element is disposed in the body and includes a signal transmission section and a signal sensing section in electrical connection with the signal transmission section. The signal amplifying portion includes a plurality of protruding structures protruding outward from the body. Each of the plurality of protruding structures is cylindrical and has a diameter of 250-400 ?m and a height of 40-75 ?m. When a portion of the body forms a surrounding portion surrounding a to-be-sensed target, a portion or an entirety of the signal sensing section is located on the surrounding portion, and the signal amplifying portion is partially or entirely in contact with the to-be-sensed target.

  • Publication number: 20250141091
    Abstract: A signal sensing device includes a body and two signal sensing elements disposed in the body. An insulating layer is sandwiched between the two signal sensing elements. Each of the two signal sensing elements incudes a signal transmission section and a signal sensing section in electrical connection with the signal transmission section. The signal transmission sections are planar antennae parallel to each other and each having an antenna shape of meander-line type. The antenna shape of each transmission section has a vertical projection on a plane parallel to each signal transmission section. The vertical projections of the antenna shapes do not overlap completely. When a portion of the body forms a surrounding portion which surrounds a to-be-sensed target, a portion or an entirety of each signal sensing section is located on the surrounding portion.
