Latest Patents

One of Cofer's latest patents is for tunable water-based microthruster devices and methods. This microthruster is designed for controlling small spacecraft and includes features such as nozzle throats with cross-sectional areas of at most 20 μm, with some as small as 6 μm. The device incorporates heaters that heat water in reservoirs to increase pressure, allowing for the ejection of water from the nozzle throats. Additionally, the microthruster can be manufactured by etching channels into layers of material or by bonding layers together after printing a heater onto one of them.

Another significant patent is for a microelectronic thermal valve, which is a microfabricated valve with no moving parts. This valve includes a reservoir of liquid in fluid communication with an outlet channel that has a throat less than 100 microns wide. The design utilizes surface tension to prevent flow until a heater increases the temperature of the fluid, resulting in the ejection of fluid that creates both thrust and cooling effects.
