The antennae 20 have high sensitivity to odors and the like. For example, when an odor is generated around the antenna 20, the odor can be detected by measuring a weak voltage generated at both ends of the antenna 20. A diagram showing such a voltage is called an antennal electrogram.

The antennae 20 are biomaterials, such as the antennae of insects such as silk moths, American cockroaches, hawkmoths, or Saturniidae. Insects may or may not be genetically engineered. The first end 21a is any end of the antenna 20.

Here, the second portion 22b of the antennae 20 is located between the first portion 22a and the second end portion 21b on the opposite side of the first end portion 21a. The second end portion 21b of the antenna 20 is in contact with the conductive material 30 in the second internal space 140b and is electrically connected to the second electrode 160b via the conductive material 30 housed in at least the second internal space 140b. NS.

The method for holding the antennae 20 according to the present embodiment is realized by using the holder 10 as described above. This will be described in detail below.

First, the first base member 120a and the second base member 120b with the first electrode 160a and the second electrode 160b attached are prepared. Then, the conductive material 30 is introduced into the first recess 121a of the first base member 120a and the second recess 121b of the second base member 120b, respectively. For the introduction of the conductive material 30, for example, a syringe equipped with a needle can be used. Here, it is preferable that the first recess 121a and the second recess 121b are filled with the conductive material 30. However, the conductive material 30 is introduced from the recess 122a and the recess 122b to the extent that it does not flow.

Next, the antennae 20 are placed on the first base member 120a and the second base member 120b. Specifically, the antenna 20 is arranged so as to pass between the recess 122a and the recess 122b. By doing so, both ends of the antennae 20 are located in the vicinity of the first electrode 160a and the second electrode 160b, respectively. The antennae 20 may be placed on the first electrode 160a and the second electrode 160b.

Then, the conductive material 30 is further introduced on the antennae 20. Specifically, both ends of the antennae 20 are covered with the conductive material 30. When the conductive material 30 is a conductive gel, by doing so, the antennae 20 can be fixed to some extent by using the viscosity of the gel.

Next, the first inner lid member 130a and the second inner lid member 130b are superposed on the first base member 120a and the second base member 120b, respectively, so as to sandwich the first portion 22a and the second portion 22b of the antennae 20. By doing so, the antennae 20 are mechanically fixed.

Then, in this state, as shown in FIG. 8, the end of the antennae 20 is slightly cut by the cutting means 40 through the first through hole 131a of the first inner lid member 130a. Further, the end of the antennae 20 is slightly cut by the cutting means 40 through the second through hole 131b of the second inner lid member 130b. The cutting means 40 is, for example, scissors or a utility knife. The antennae 20 can be cut in the conductive material 30.

Further, the conductive material 30 is introduced into the first through hole 131a of the first inner lid member 130a and the second through hole 131b of the second inner lid member 130b. Here, it is more preferable that the entire first through hole 131a and the second through hole 131b are filled with the conductive material 30. Next, the first outer lid member 150a and the second outer lid member 150b are attached to the first inner lid member 130a and the second inner lid member 130b, respectively. By doing so, the first internal space 140a and the second internal space 140b are sealed. Here, in order to prevent the volatilization of moisture and the like from the conductive material 30, the first internal space 140a and the second are such that the conductive material 30 at least partially touches the first outer lid member 150a and the second outer lid member 150b. It is preferable that each of the internal spaces 140b is filled with the conductive material 30. The first internal space 140a and the second internal space 140b need only be a space substantially closed by the first outer lid member 150a and the second outer lid member 150b, and do not necessarily have to be tightly sealed. Therefore, a slight gap may be formed between the first inner lid member 130a and the first outer lid member 150a, and between the second inner lid member 130b and the second outer lid member 150b.

Next, the operation and effect of this embodiment will be described. According to the holder 10 and the holding method according to the present embodiment, the antenna 20 can be easily attached by cutting the end portion.

When an odor or the like acts on the exposed portion of the antennae 20 between the first holding portion 110a and the second holding portion 110b, a voltage change occurs between the first electrode 160a and the second electrode 160b. By detecting the voltage change, it is possible to detect the odor or the like in the space where the antenna 20 is exposed.

According to this embodiment, the antenna 10 can easily and stably hold the antennae 20 and detect odors and the like. In addition, volatilization of moisture and the like from the conductive material 30 and drying of the antennae 20 are suppressed, and long-term detection is possible. Further, since the holder 10 is excellent in portability, a portable detection device can be realized.

Next, the operation and effect of this embodiment will be described. In this embodiment, the same actions and effects as those in the first embodiment can be obtained. In addition, stable long-term detection can be achieved.

FIG. 10 is a tactile electrogram obtained by using a holder as shown in FIGS. 1 to 7. As the antennae 20, the antennae of the silk moth were used. Then, by operating the solenoid valve, the silk moth's sex pheromone, Bombicole, was supplied in a pulsed manner to the antennae. Here, the pulse width was set to 20 ms, and the pulse period was set to 500 ms. The voltage signal from the antenna was amplified about 70 times by the preamplifier.

As shown in FIG. 10, it was confirmed that the antennae electrogram can be normally obtained from the antennae held by the holder.
