Abstract
A dosing device of the present disclosure is a dosing device that emits information by vibration of the device itself, the device including an ultrasonic oscillator inside, in which a curvature of an outer surface located on a vibration direction of the ultrasonic oscillator is 0.18 or more and 0.50 or less.
Claims20
A dosing device that emits information when the dosing device itself vibrates, the dosing device comprising:
- an ultrasonic oscillator located within the dosing device,
- wherein a curvature of an outer surface located on a vibration direction of the ultrasonic oscillator is 0.18 or more and 0.50 or less.
An information acquisition system for a dosing device, comprising:
- the dosing device that emits information when the dosing device itself vibrates, the dosing device comprising:
- an ultrasonic oscillator that is provided inside,
- wherein a curvature of an outer surface located on a vibration direction of the ultrasonic oscillator is 0.18 or more and 0.50 or less;
- and
- the information acquisition system for the dosing device further comprises a processing device;
- and
- a receiver that acquires the information from the dosing device by receiving an oscillating ultrasonic signal from the ultrasonic oscillator and transmits the acquired information to the processing device.
4 more elements
A wearable device configured to transmit information, comprising:
- a rectangular prism-shaped piezoelectric element including opposing first and second main surfaces, opposing first and second side surfaces, and opposing third and fourth side surfaces,
- a housing comprising the prism-shaped piezoelectric element,
- wherein the first main surface of the prism-shaped piezoelectric element is fixed to an inner wall surface of the housing.
