The Purdue Research Foundation Office of Technology Commercialization updates the innovations on its Available Technologies page on a regular basis. Over the course of a month, the hundreds of innovations already on the page are joined by dozens of others; all are available for licensing and other commercialization activities.
Here are five of the newest technologies listed on the OTC website. To learn more, contact otcip@prf.org and include the tracking code in the subject line:
AppStreamer: Reducing Mobile Device Storage Requirements through Predictive Streaming. 2020-BAGC-69127
Researchers at Purdue University have developed a technology for reducing the amount of storage space required to run mobile applications via streaming data from cloud or nearby servers. It also improves the speed of starting an app, as the data is cached on the device or streamed from a nearby edge rather than being downloaded from the remote central server.
Dual Rotor Homopolar AC Machine for Hybrid and Electric Vehicles. 2021-SUDH-69245
Researchers at Purdue University have developed dual rotor homopolar alternating current machines (DHAMs) that can operate either as a motor or a generator. The Purdue researchers’ DHAMs can be constructed without rare-earth materials while meeting the torque requirements of the vehicular market. They also have a wide constant power speed range, making them ideal for applications such as motors for flywheel energy storage systems or electric vehicles.
Residential DC Nanogrid System. 2021-ORE-69439
Researchers at Purdue University have developed a centralized DC power distribution system capable of regulating DC power generation, distribution and storage while also integrating with existing AC infrastructure. This technology is intended for use in residential nanogrid systems to minimize losses associated with AC/DC and DC/AC conversions.
Method for Increasing Short Circuit Robustness. 2018-MORI-68146
Researchers at Purdue University have developed a new method to improve the robustness of silicon carbide metal oxide semiconductor field effect transistors, or MOSFETs. By increasing the gate oxide capacitance and decreasing the thickness of the gate insulator, researchers have improved the MOSFETs’ short circuit withstand time. This makes MOSFETs more cost effective, more reliable and less susceptible to failure.
Watermarking with Inkjet Edible Bioprinting. 2022-KIM-69723
Researchers at Purdue University have created a method to print edible watermark taggants onto pharmaceuticals. Such taggants place the security of the drug in the dosage form itself instead of the secondary packaging, allowing traceability in case the drug and packaging are separated. The printed watermark also protects against counterfeiting of drugs, with other properties that prevent duplication of the watermark.
