A smart clothing and backpack system enables a user to perform many actions. The smart clothing includes circuitry and/or is made of a conductive material enclosed in an insulation material. The smart clothing includes a set of sensors configured to detect body information. The smart clothing includes multiple electromagnets configured to adjust a size of the smart clothing. The electromagnets are configured to have an increased attraction to make the smart clothing tighter on the body of the user. The system includes a smart backpack to communicate with the smart clothing. The smart backpack includes a Radio Frequency IDentification (RFID) reader configured to detect RFID tags on or in items within the smart backpack. Many other features are able to be implemented with the smart clothing and backpack system. The smart clothing is able to include a wetsuit configured to communicate with a surfboard and/or a backpack.

A diving suit waterproof connector having a lighting device, includes: a fixing tube part watertightly connected to an end of each of sleeves of the diving suit; and a fastening tube part connected to a neck portion of an underwater work glove, wherein the fixing tube part includes fastening protrusions; a rubber ring press-fitted thereto; and a first contact terminal, and the fastening tube part includes coupling protrusions; a second contact terminal; and a lighting part electrically connected to the second contact terminal.

Provided is an electricity generating module. The electricity generating module comprises: a cylinder; a piston that reciprocates inside the cylinder; and a power generating fiber of which one end is fixed to the piston and the other end is fixed to the cylinder, and of which the length varies according to the reciprocating of the piston, wherein, as the length of the power generating fiber varies, a potential value of the power generating fiber varies, and electricity is generated by using the varied potential value of the power generating fiber.

A dynamically configurable wetsuit includes a torso part having a pair of partial arm sleeves and a pair of partial leg pants. A distal end of each of the pair of partial arm sleeves and the pair of partial leg pants has a first connector that includes a set of outward-facing ridges. The wetsuit further includes a pair of arm parts and a pair of leg parts. Each of the pair of arm parts and the pair of leg parts having a second connector at a proximal end for detachable connection with one of the first connectors of the torso part, each second connector including a set of inward-facing ridges. The wetsuit further includes a fastener system to maintain a connection between the first and second connectors.

A wetsuit for aquatic activities may include a wetsuit material having a first surface and an opposite second surface. The wetsuit has a portion comprising one or more paddling assist members that may be configured to lay flat while inserting the portion into water and extend outward from the surface of the wetsuit when the portion is drawn backward during a paddling stroke movement to provide greater resistance to the movement, increasing thrust provided by the movement.

To provide a body protection product such as a wetsuit that does not require a troublesome and time-consuming step such as machine sewing does not cause discomfort for the wearer, and does not result in a loss to the degree of freedom in terms of design. A wetsuit (10), in which a highly stretchable and elastic sheet-shaped fabric is draped to match the concave and convex features of the body shape off a wearer and a plurality of fabric pieces (11) are prepared, an adhesive (3) is applied to the draping surfaces of the fabric pieces (11), and the draping surfaces are then pressed against each other and joined without stitching, whereby a three-dimensional clothing base (1) is formed. Next, an adhesive (4) is applied to the surface of the clothing base and stretching is performed, whereby the surface of the clothing base is covered by a stretchable covering material (2) formed to match the shape of the clothing base (1). The clothing base (1) and the covering material (2) are compressed under heating and thereby made to adhere to each other.
