Latest Patents

Michael Purfield holds a patent for a temperature-actuated valve, fluidic device, and related methods of use. This patent describes temperature-actuated valves and devices that include these valves. In one embodiment, the temperature-actuated valve features a heat-shrink film with a perforation extending partially in a first direction. The valve is designed to open when a portion of the heat-shrink film, including the perforation, is heated above a threshold temperature. This heating causes the heat-shrink film to contract along a second direction, which is perpendicular to the first direction, thereby creating an aperture that allows fluid to pass through. Additionally, the valve includes a leakage-mitigation feature that limits fluid flow through the perforation when the valve is in a closed configuration.
