Scan for outdated or missing drivers - takes under a minuteDriver Scan →Clear out junk files and repair common Windows errorsFree Scan →It was a research concept, not a retail security system: damage to layered polymer foils was designed to bring separated reactants together and trigger foaming. The idea, reported in 2014, was inspired by a beetle and proposed as a possible way to protect cash machines without electrical components.
How does the foaming security concept work?
The concept relies on mechanically triggered mixing. Reactants are kept apart in polymer foils; when the material is damaged, the foils rupture and the contents mix, producing foam. The trigger is physical damage to the surface rather than an electrical sensor or powered mechanism.

The 2014 account described the approach as inspired by a beetle. That description explains the design inspiration; it does not mean the material reproduces a beetle’s biology in every detail. Chemistry World reported the concept on 20 March 2014.

The cash-machine use was presented as a potential application, not as a deployed product. The available accounts describe a developing research concept and do not document installation in commercial ATMs or measurable performance in real-world theft attempts.
#1 Best Overall
- 1080P HD USB Camera with CMOS IMX323 Sensor: This USB industrial camera features a 1920×1080 resolution CMOS IMX323 sensor, delivering sharp images and accurate color reproduction for industrial inspection and PCB repair. With 30fps high frame rate, it supports MJPEG/YUY2/H.264 compression formats. The H.264 compression of this USB camera reduces bandwidth usage by 50% for smooth live streaming (Windows software for H.264 capture is provided).
- Manual Zoom Lenses for USB Industrial Camera: Equipped with a 2.8-12mm CS mount varifocal lens, this industrial USB camera offers flexible manual zoom control—easily adjust focal length to switch between wide-angle views (for large-area inspections) and close-up precision (for tiny PCB components).
- 0.01Lux Low Light USB Camera Performance: As a professional industrial inspection camera, it adopts a 2MP 1/2.9 IMX323 Color CMOS sensor, enabling it to capture clear images even in 0.01Lux low light conditions. This low light USB camera is ideal for various dim environments in industrial applications.
- Plug-and-Play USB Camera with Wide Compatibility: This mini USB camera is plug-and-play, requiring no driver installation. With a 4pin to USB connector, it easily connects to PCs and is compatible with Linux, Windows, Android, and Mac OS. Suitable for various devices like kiosks, vending machines, and computers for video conference.
- Versatile Applications of 1080P USB Camera: The 1080P USB camera is widely used in industrial settings such as video surveillance system, industrial inspection, PCB repair, ATM monitoring, and robotic vision. It also works well for live streaming, video conference, dashcam, and applications needing gesture tracking, iris recognition, depth and motion detection, thanks to its 0.01Lux low-light sensitivity and low distortion lens.
ETH Zurich later identified the work as Jonas Halter’s self-defending-surface research and noted media coverage, including a July 2014 television broadcast. Media coverage establishes that the research attracted attention; it is not evidence of commercial adoption. ETH Zurich’s Functional Materials Laboratory posted that coverage on 14 July 2014.
What was actually published?
The research paper is “Self-defending anti-vandalism surfaces based on mechanically triggered mixing of reactants in polymer foils,” by Jonas G. Halter, Nicholas H. Cohrs, Nora Hild, Daniela Paunescu, Robert N. Grass and Wendelin J. Stark. The Royal Society of Chemistry lists it as a 2014 accepted manuscript, DOI 10.1039/C3TA15326F. The Royal Society of Chemistry record identifies the paper and its authors.

The cited coverage does not provide a quantitative performance result suitable for judging how much foam the material produced, how quickly it reacted, or how effectively it would deter or impede an attacker. It also does not establish head-to-head testing against existing ATM security measures. The concept should therefore be understood as a proposed material response to damage, not a proven security guarantee.

Is it something consumers or ATM owners can buy?
The sources identify no named commercial system, retail product, compatible accessory or replacement part based on this research. The work is a materials-research concept; the available evidence does not establish an off-the-shelf security product.
