Abstract

A sensor device includes: a first portion that is formed of an inorganic semiconductor material, includes a control module, and is reusable; a second portion that is formed of an organic material and separably coupled to the first portion; and a sensor that is disposed in at least one of the first and second portions.

Claims

1. A sensor device comprising:

a first portion that is formed of an inorganic semiconductor material, includes a control module, and is reusable;

a second portion that is formed of an organic material and separably coupled to the first portion; and

a sensor that is disposed in at least one of the first and second portions.

2. The sensor device according to claim 1, wherein the second portion includes an operation start trigger circuit that generates a trigger signal for operating the first portion, and the first portion starts an operation by the trigger signal input from the second portion.

3. The sensor device according to claim 2, wherein the senor is disposed in the first portion and starts sensing by the input of the trigger signal from the second portion.

4. The sensor device according to claim 2, wherein the operation start trigger circuit generates the trigger signal when a radio signal is received by a first communication method from outside.

5. The sensor device according to claim 2, wherein the sensor is disposed in the second portion, and the operation start trigger circuit generates the trigger signal when a value detected by the sensor exceeds a level, and supplies the trigger signal and sensor information detected by the sensor to the first portion.

6. The sensor device according to claim 5, wherein the first portion includes a second sensor, and the second sensor starts an operation when the trigger signal is received from the second portion.

7. The sensor device according to claim 1, wherein the first portion and the second portion are coupled to be separable from each other by a connection portion through a physical contact.

8. The sensor device according to claim 1, wherein the first portion and the second portion are coupled to be separable from each other by a non-contact connection portion.

9. The sensor device according to claim 4, wherein when a radio signal is received from outside by the first communication method, the operation start trigger circuit compares identification information included in the radio signal and stored identification information with each other, and when the identification information of the radio signal and the stored identification information are consistent with each other, the operation start trigger circuit generates the trigger signal.

10. The sensor device according to claim 1, wherein the second portion includes a coil type antenna, and when a radio signal is received from outside by the first communication method, the second portion is operated by using a power generated from the radio signal.

11. The sensor device according to claim 1, wherein the first portion includes a power supply, and the second portion is operated by using a power from the power supply.

12. The sensor device according to claim 1, wherein the second portion includes an energy harvester and is operated by using energy generated in the energy harvester.

13. The sensor device according to claim 8, wherein the second portion includes a coil type antenna, and when a radio signal is received by the first communication method from outside, the second portion supplies at least a part of the radio signal to the first portion by the non-contact connection portion, and the first portion generates a power from the radio signal and uses the power for an operation of the control module.

14. The sensor device according to claim 1, wherein the first portion includes a communication module that conducts a short distance wireless communication by a second communication method, and the communication module transmits sensor information acquired by the sensor to outside.

15. The sensor device according to claim 1, wherein the first portion includes a power supply, and a supply of a power from the power supply to the control module is not performed while no trigger signal is input.
