Abstract

The present technology relates to a wearable device and an electricity supply system that make it possible to reduce the stress on a user in relation to electricity supply. A power generating unit is provided on the external world-side surface or the eyeball-side surface of a contact lens-type wearable device. The power generating unit generates electric power by chemical reaction with a substance contained in a secretion or a body fluid of a user wearing the wearable device, and a power managing unit supplies the electric power obtained in the power generating unit to each part of the wearable device. Thus, the power generating unit performs electricity generation using the secretion or the body fluid of the user as fuel; thereby, electric power can be stably supplied, and the stress on the user in relation to electricity supply can be reduced. The present technology can be applied to a contact lens-type wearable device.

Claims

1. A wearable device, comprising:

a main body, wherein

the main body comprises an exterior side and an interior side, and

the wearable device is mountable on an eyeball of a user from the interior side of the main body;

a film that is one of attachable to the exterior side of the main body or detachable from the exterior side of the main body;

an enzyme on the film; and

first circuitry on the film, wherein the first circuitry is configured to;

receive one of a sugar or a sugar component associated with the user;

generate electric power based on a chemical reaction of the enzyme with one of the received sugar or the received sugar component; and

supply the generated electric power to the main body.

2. The wearable device according to claim 1, wherein one of the received sugar or the received sugar component is contained in one of a secretion fluid of the user or a body fluid of the user.

3. The wearable device according to claim 2, wherein the first circuitry is further configured to store the generated electric power.

4. The wearable device according to claim 2, wherein the secretion fluid is a tear of the user.

5. The wearable device according to claim 2, wherein the body fluid is at least one of blood or aqueous humor.

6. The wearable device according to claim 2, wherein the first circuitry covers an outer periphery of the film.

7. The wearable device according to claim 2, wherein the main body further comprises second circuitry configured to:

determine a concentration value of one of the received sugar or the received sugar component; and

store the determined concentration value.

8. The wearable device according to claim 2, wherein the main body further comprises second circuitry configured to monitor a change in a concentration of one of the sugar or the sugar component.
