Title: Sensor and sensing device
Inventor: SHINOBU WAKAKO
IPC: H03H9/17
Filed: 2019-11-29
Abstract: To provide a sensor for detecting a sensing object in a sample liquid utilizing a frequency change, with which the detection of the sensing object is carried out stably, irrespective of a particle size.SOLUTION: A sensor is provided with an adsorption layer formed to excitation electrodes 45, 46, 48 and 49 on the surface of a crystal vibrator 4, to which a sample liquid is supplied, in such a way that the index values of surface roughness are mutually different preset values. Therefore, it is possible to guarantee a function by which sensing objects P2, P3 which are large in diameter can be adsorbed and sensed. As compared with the case where all adsorption layers are composed of regions whose surface roughness is coarse, the ratio occupied by the area of adsorption regions whose surface roughness is coarse is low and the degree of contribution is small, so that statical values hardly vary. As a result of this, when the same sample liquid is supplied, random variation in statical values obtained between a plurality of sensors is small and the difference in sensing performance between the sensors is small.SELECTED DRAWING: Figure 3
