Researchers have combined a longstanding printing method with materials science to produce a new way to develop wearable technology and other smart garments.
Researchers at Oregon State University have developed a printable ink based on binary metal iodide salts that can thermally transform into a perovskite, one of a broad class of crystalline materials that is better known for its use in photovoltaics. This transformation paves the way for electronic components, like circuits, to be directly woven onto textiles as a new way to fabricate wearable electronics, they said.
Thanks to the perovskite film, researchers in the team of Chih-Hung Chang, professor of chemical engineering at Oregon State, succeeded in printing negative-temperature-coefficient thermistors directly onto woven polyester at temperatures as low as 120 degrees Celsius which is just higher than the boiling point of water.

“Pellucere has exceeded our technical performance expectations and we are glad to have Fortistar’s strong operations-focused team recognize and join in the execution of the company’s growth plans,” said George Coyle, Managing Partner at EIC.
In 2021, Pellucere expects to complete installation of the MoreSun coating on more than 500 MW of retrofit solar projects in the U.S., Canada, Europe, and Africa.

More on MoreSun. Pellucere was spun out of Oregon State University to commercialize the nano-technology developed by Dr. Chih-hung Chang and Dr. Seung-Yeol Han. The company has also developed and manufactures a patented robotic applicator system for the MoreSun coatings to enable high-precision, high-efficiency field application of the product.

HOUSTON, Feb. 23, 2021 /PRNewswire/ Pellucere Technologies, Inc., a U.S.-based sustainable technology focused company that manufactures anti-reflective and anti-soiling coatings for solar, automotive, and consumer electronics, announced today that Fortistar, a privately-owned investment firm that provides capital to build, grow and manage companies that address complex sustainability challenges, is co-investing alongside existing investor Energy Innovation Capital ( EIC ) to fund the rapid growth of the company.
MoreSun s Anti-Soiling technology added up to 12% additional energy during a multi-year field test in the California Desert. The modules in the photo were not washed for a full year.
Oregon State’s Year in Science
December 26, 2020
Coming out of a year in which new technology was used to create a first-ever vaccine, it’s to be expected that scientific progress abounds. In the backyard of every Corvallisite sits a university where these breakthroughs can be developed and seen in use every day. Here is a list of the top discoveries to come out of Corvallis in 2020.
No. 1: Electronic Noses
Assistant professor of chemical engineering Cory Simon led research into the development of an electronic nose that allows for the monitoring of air quality. The goal is to detect safety threats and diagnose diseases which can be measured by the gases in a patient’s breath. Collaborating with engineering professor Chih-Hung Chang, the research focused on materials known as metal-organic frameworks, which have pores that can selectively absorb gases – much like a sponge.
