    Abstract: A cooling fan with high heat-dissipating performance includes a plurality of blades; and a frame for receiving the blades therein, wherein the frame has a reduced height for exposing the blades to outside of the frame so as to allow air to enter into the frame via a top portion and a peripheral portion of the blades to improve air introduction and heat dissipating efficiency of the cooling fan. A cover may be mounted to a top surface of the frame, and formed with a plurality of openings for allowing air to enter into the frame through the openings; such an arrangement cam effectively enhance air intake and working efficiency of the cooling fan.

    Abstract: A centrifugal fan, comprising a frame and a first guide portion. The frame comprises a bottom portion and a curved wall connected thereto. The curved wall comprises an airflow inlet. The first guide portion disposed along the curved wall at the bottom portion comprises a beginning area, a middle area, and an ending area. The middle area connects the beginning and the ending areas, and the beginning area extends from the airflow inlet. The beginning area has a width less than that of the ending area, and the beginning area has a height greater than that of the ending area.

    Abstract: A triboelectric generator can include respective contact members including a first contact member and second contact member. The respective contact members can be movable with respect to each other such that the respective contact members separate from each other in a first configuration and contact each other in a second configuration. The first contact member can include a first conductive layer and a contact layer. The second contact member can be spaced apart from the first contact member in the first configuration and can include an insulating contact layer and a second conductive layer. The insulating contact layer can be configured to come into contact with the contact layer of the first contact member and the transition of the respective contact members from the first configuration to the second configuration can create triboelectric charges. In some examples, the first contact member can include a non-contact insulating layer.
