Abstract: A wearable device includes a plurality of power generation devices; at least one of an electrical storage device, a computation device, a storage device, or a communication device; a plurality of modularized unit blocks, wherein a first modularized unit block of the plurality of modularized unit blocks comprises a first power generation device of the plurality of power generation devices, and wherein a second modularized unit block of the plurality of modularized unit blocks comprises at least one of the electrical storage device, the computation device, the storage device, or the communication device; and a plurality of holding members, wherein each of the plurality of holding members is configured to accommodate a corresponding modularized unit block of the plurality of modularized unit blocks.

Abstract: To detect at least either of the states of an attachment target and a surrounding environment without any time restriction. Provided is an information processing device including: a power generation signal acquisition unit configured to acquire a power generation signal based on power generation by at least one power generation device; and a determination unit configured to determine at least either of states of an environment surrounding the power generation device and an attachment target to which the power generation device is attached, on the basis of the power generation signal.

Abstract: [Object] To provide a wearable device capable of being configured by selecting a desired power generation device. [Solution] A wearable device includes: at least one power generation device; or a power generation device and at least one of an electrical storage device, a computation device, a storage device, and a communication device. Any one of or a combination of those devices is configured of a unit block that is modularized.
