A generator includes a first cylindrical member and a second cylindrical member. The first cylindrical member includes a first dielectric layer including a first material that has a first rating on a triboelectric series; and a first conductive strip disposed around an exterior surfaces of the first cylindrical member. The first conductive strip includes a second material that has a second rating on the triboelectric series that is different from the first rating. The second cylindrical member is disposed about the first cylindrical member and includes a second dielectric layer that includes the first material. The second cylindrical member also includes the second material and at least one second conductive strip disposed around an interior surface of the second cylindrical member. A sliding mechanism causes lateral relative motion between the first cylindrical member against the second cylindrical member, generating an electric potential imbalance between the first and second conductive strip.
