SENSOR, DETECTION DEVICE, AND METHOD FOR MANUFACTURING SENSOR

The embodiment of the invention provides a sensor, a detection device and a method for manufacturing the sensor, and the sensor comprises the components of a substrate which comprises two parts, at least one part of the first part extends along a first direction, and the second part is arranged at one end of the first part in the first direction; the electrode substrate is arranged on the first main plane of the substrate and is arranged at the other end of the first part in the first direction; the first electrode is arranged on the electrode substrate, the size of the first electrode is smaller than that of the electrode substrate, the first electrode comprises a first working electrode and a first counter electrode, the surface of the first working electrode comprises a biological coating, and the biological coating is used for reacting with a target substrate; and the first electrode interface is arranged on the first main plane and arranged on the second part, and the first electrode interface is connected with the electrode substrate through a first lead. The sensor provided by the invention can reduce the foreign matter reaction of the human body after the sensor is implanted into the human body.
