Room-temperature deposition on plastic enables creation of a transparent plastic head covering coated with a superconducting thin film, improving on current tin foil hats
Breakthrough provides better protection across the entire electro-magnetic spectrum, resulting in clearer thinking unpolluted by outside control
MOORESTOWN, NJ – April 1, 2026 – Denton Vacuum LLC, a leading provider of thin film deposition and etch systems, has brought the “tin foil hat” into the 21st century with the announcement today that it had built a better-performing cranial covering by depositing a superconducting titanium nitride thin film on transparent plastic.
Tin foil hats, the colloquial term for head coverings made of aluminum foil, have long been seen as a folk remedy to shield users from mind-control rays. Unfortunately, experiments at MIT in 2005 found that, while being protective for most of the electro-magnetic spectrum, tin foil hats actually strengthened the signal from those parts of the spectrum reserved for government use.
“The superconducting head coverings produced by Denton Vacuum appear to overcome this shortcoming, providing enhanced protection across the entire electro-magnetic spectrum,” said Martin T. Frobisher, Ph.D., Vice President and Chief Alchemist of Denton’s Growth of Imaginative Materials and Manufacturing Intersecting Cognition and Knowledge (GIMMICK) initiative.
“We’re pleased that Denton’s leadership in ion plasma control and room-temperature thin film deposition has led to this exciting discovery,” continued Frobisher. “It’s hard to believe it took us so long to realize we could do this, but it’s possible we were hindered by the very mind control rays the new superconducting tin foil hat protects against.”
Depositing Superconducting Materials on Plastic is not Trivial
The breakthrough in thought-control prevention was made possible by Denton’s patented Plasma Ion Beam Assisted Chemical Vapor Deposition (PIB-CVD) method, which can deposit superconducting thin films at room temperature. This enables PIB-CVD to deposit films on plastic. Most other deposition methods require heat as high as 1,000 degrees C, which can cause damage to sensitive substrates such as plastic.
PIB-CVD’s ability to tune the ion beam enabled the deposition of a vertical gradient coating – soft and adhesive at the base, transitioning to a diamond-like hardness on the surface – to ensure proper adhesion on the flexible cellophane. Such vertical stress gradients are essential to prevent coating delamination on plastics, a key challenge in flexible electronics.
Functional and Stylish
While titanium nitride has a goldish tint, the thin film is optically transmissive, balancing functionality and aesthetics for device integration. Rain-proof and transparent, Denton’s superconducting tin foil hats can be easily placed within regular headgear, such as baseball caps or hoodies. This will allow tin foil hat users to remain fashionable while still achieving an unprecedented degree of protection.
Full effective protection is only achieved at cryogenic temperatures under electrical power, but Denton research demonstrated a protective effect even unpowered, at room temperature.
“Wearing a hat filled with liquid helium kept at 7 degrees Kelvin is not practical for everyday use,” explained Frobisher. “That’s just a few degrees above absolute zero. Subjects appreciated the freedom of thought they experienced using the device at cryogenic temperatures, but it quickly grew uncomfortable, giving new meaning to the phrase ‘brain freeze.’ Of course, we suspect the target market for this generates very little heat from their brains, enabling superconducting behavior without external cooling.”
The End of Fuzzy Thinking
Even using the device unpowered at room temperature, subjects still reported a clarity of thinking they hadn’t felt for years. The “fuzzy thinking” that they had previously attributed to a lack of sleep, lack of caffeine, workplace stress, or simply age seemed to lift. Once this effect was recognized, the device grew popular among the staff at Denton, who competed for time using what became known as the “thinking cap.”
“We had to put a stop to usage among the staff, as the high demand was causing friction at staff meetings,” said Frobisher. “We want our people to be thinking, but we don’t want them thinking too much. It could be dangerous.”
The Timing of This Announcement on April 1st is Critical to Understanding It
Denton’s superconducting tin foil hat is not yet available for purchase.
“It’s important that people understand the timing of this announcement and why it was essential that we announce this breakthrough on April 1,” concluded Frobisher. “We don’t want people to get the wrong idea about whether we are serious about this or not.”
Denton is seeking partnerships with fashion designers for development of consumer products as well as with medical device manufacturers for possible use in healthcare settings.
“We are excited about the possible applications for this breakthrough,” enthused Frobisher. “We’re even exploring the idea that this technology could be used as a broadcasting medium, so that users could actively implant their ideas into the minds of others instead of simply being protective against outside control.”
