01 / Multi-target radiant heat sensing system

Project summary:

The Electronics and Communications Research Institute (ETRI), headquartered in Daedeok Science Park, Daejeon, South Korea, is a non-profit government-funded research institution. Founded in 1976, ETRI has successfully developed high-end information technologies such as high-density semiconductor chips, micro supercomputer (TiCOM), digital mobile communication system (CDMA), and wireless broadband technology (WiBro), and is a leader in the field of telecommunications research in Korea.

Based on a deep learning object recognition model, the technology can accurately identify the inner canthus measurement targets recommended by the international standard (IEC 80601-2-59) and monitor the heating status of multiple objects in an enclosed space. In addition, it provides more accurate measurements of bolometric heat by using LiDAR modules and blackbody correction for object distance and ambient errors. The technology measures more accurate multi-object biometrics for early detection of unusual objects, diseases, abnormal signs and risk levels.

The project has achieved small-scale production, and the foreign side hopes to cooperate through technology transfer and other means.

02 / Broad spectrum antibacterial and antiviral membrane

Project summary:

The Cornell University Technology Licensing Center (CTL) is the technology transfer office of Cornell University. CTL's mission is to bring Cornell University's scientific discoveries, technological innovations, and medical advances to market for the benefit of society and to foster the creation and growth of new businesses to support economic development in the United States and around the world. The office manages technology across Cornell's campuses, including the Ithaca campus, Weill Cornell Medical College (WCM), Cornell Tech (in New York) and Cornell Agricultural Tech (in Geneva).

The technology is a safe, inexpensive and scalable membrane with rapid and long-lasting efficacy against a wide range of bacteria and viruses. After chlorination, the membrane achieved a reduction of more than 6 logarithms in a matter of minutes against all tested bacterial strains, including gram-positive, Gram-negative, drug-resistant, and clinical bacterial mixtures. After just 10 minutes of exposure, the membrane inactivates SARS-CoV-2, reducing its activity by more than 5 logarithms.

In terms of market prospects, such antiviral membranes can be attached to surfaces that are in frequent contact with the virus or used in air filters and personal protective equipment (PPE) to provide continuous protection and minimize the risk of transmission. The project is in the laboratory results stage, and the foreign party hopes to develop and cooperate with each other after authorization.

03 / New soft, stretchable sensing materials that can be used as sensors or high-speed actuators

Project summary:

The Harvard Office of Technology Development (OTD) promotes the public good, improves lives, transforms industries, and creates significant social and economic value by advancing science, fostering innovation, and transforming Harvard's new inventions into usable and socially beneficial products.

Harvard University researchers have developed a new soft, stretchable material that could be used as a sensor or high-speed actuator. The invention adopts a simple and low-cost design and can be made into a completely transparent, highly stretchable, biocompatible and biodegradable sensing material. As such, it is ideal for a range of applications such as robotics, adaptive optics, energy harvesting, or touch screens for mobile electronic devices. The device consists of a dielectric elastomer with a layered electrolyte and a dielectric (LEAD) that deforms rapidly under voltage. For sensor applications, the design can operate at very low voltages (well below 1V if necessary), thus broadening possible applications such as wearable electronics, soft robotics, or biomedical applications. Due to the use of ionic materials, they are biocompatible and therefore implantable in the body. Using this elastomer as an actuator on a smartphone display can turn the entire glass surface into a hi-fi speaker or haptically sensitive keyboard. In addition, the technology can also be used in the field of adaptive optics.

The project is in the laboratory results stage, and the foreign party hopes to develop and cooperate with each other after authorization.

04 / Highly reversible battery anodes chemically bonded at the interface

Project summary:

The Cornell University Technology Licensing Center (CTL) is the technology transfer office of Cornell University. CTL's mission is to bring Cornell University's scientific discoveries, technological innovations, and medical advances to market for the benefit of society and to foster the creation and growth of new businesses to support economic development in the United States and around the world. The office manages technology across Cornell's campuses, including Ithaca, Weill Cornell Medical College (WCM), Cornell Tech, and others.

This technology enables electrodes with strong chemical bonds between metal deposits and electrically conductive substrates to precisely control the electrodeposition of aluminum and provide excellent reversibility (99.6% to 99.8%). For aluminum anodes, reversibility can be maintained over a considerable cycle time (> 3600 hours), and the actual capacity is two orders of magnitude higher than previously estimated. Studies have shown that these properties arise due to the elimination of weak electron (e-) transport paths, as well as the aggressive non-planar deposition of aluminum through specific metal-substrate chemical bonding. The technology has the advantages of safe and sustainable, higher energy and lower cost of electrical energy storage, and can be widely used in fuel cells, semiconductor manufacturing, energy storage and other fields.

The project is in the laboratory results stage, and the foreign party hopes to cooperate after authorization.
