Latest Patents

Among his latest innovations, Fu-Hua Chu has developed two notable over-current protection devices. The first device comprises first and second electrode layers with a PTC material layer laminated in between. This PTC material layer includes a polymer matrix, a conductive filler, and a titanium-containing inner filler. The polymer matrix is based on a fluorine-free polyolefin polymer, while the titanium-containing inner filler is represented by a compound with the general formula MTiO, where M signifies a transition metal or alkaline earth metal. The titanium-containing inner filler constitutes 1-9% by volume of the PTC material layer.

The second device also features a first metal layer, a second metal layer, and a heat-sensitive layer laminated between them. This heat-sensitive layer exhibits a positive temperature coefficient (PTC) characteristic and consists of a first polymer and a conductive filler. The first polymer is polyvinylidene difluoride (PVDF), which exists in various phases, including α-PVDF, β-PVDF, and γ-PVDF. The total amount of these phases is calculated as 100%, with α-PVDF accounting for 48% to 55%. The conductive filler used in this device is a metal-ceramic compound.
