1. A generator comprising:
respective contact members comprising a first contact member and a second contact member, the respective contact members being movable with respect to each other such that in a first configuration the respective contact members separate from each other and in a second configuration the respective contact members contact each other;
the first contact member comprising:
a first conductive layer; and
a contact layer adjacent to the first conductive layer, the contact layer comprising an adhesive contact layer;
the second contact member spaced apart from the first contact member in the first configuration, the second contact member comprising:
an insulating contact layer; and
a second conductive layer adjacent to the insulating contact layer;
wherein the insulating contact layer is configured to come into contact with the contact layer of the first contact member in the second configuration; and
wherein transition of the respective contact members from the first configuration to the second configuration creates triboelectric charges.
