Abstract

A digital signage system includes a transducer configured to transform a pressure to an electrical signal; a control apparatus configured to change information in association with the intensity of the electrical signal; and an output apparatus configured to output the information to an output target based on a command of the control apparatus.

First claim

What is claimed is:

1. A digital signage system comprising:
a transducer configured to transform pressure into an electrical signal;
a control apparatus configured to change information in association with the intensity of the electrical signal; and
an output apparatus configured to output the information to an output target based on a command of the control apparatus, wherein
the transducer includes
a first electrode,
a second electrode, and
an intermediate layer provided between the first electrode and the second electrode, the intermediate layer
being made from silicone rubber,
having a front surface and a back surface that are each subjected to a surface modification process and an inactivation process, such that the amount of siloxane bonds at the front surface is different from the amount of siloxane bonds at the back surface, and

wherein a hardness of the intermediate layer at a time of pressurizing the intermediate layer on the side of the first electrode is different from a hardness of the intermediate layer at a time of pressurizing the intermediate layer on the side of the second electrode.

2. The digital signage system according to claim 1 ,
wherein the output target is the transducer.

3. The digital signage system according to claim 1 ,
wherein the transducer detects a motion of an object as the pressure and outputs the converted electrical signal to the control apparatus.

4. The digital signage system according to claim 1 ,
wherein the transducer detects a position of an object as the pressure and outputs the converted electrical signal to the control apparatus.

5. The digital signage system according to claim 1 ,
wherein the transducer includes a plurality of transducers, and
the plurality of transducers are arranged on a predetermined surface on which an object can apply the pressure.

6. The digital signage system according to claim 1 , wherein
a hardness ratio between a universal hardness of the front surface of the intermediate layer and a universal hardness the back surface of the intermediate layer is equal to or greater than 1.07.
