Optical Coherence Tomography (OCT) and the newer line-field confocal OCT (LC-OCT) offer dermatologists real-time, non-invasive imaging of tattoo pigment clusters in the dermis visualizing pigment […]
Epidermal electronic tattoos (ultra-thin, conformal circuits printed on temporary/transfer substrates) have matured into battery-free NFC/near-field devices that can store small data, run passive sensors, or […]
A string of analytical and epidemiological studies has shown that particles and chemical impurities from tattoo inks (notably carbon black and polycyclic aromatic hydrocarbons, PAHs) […]
Market surveillance rounds in several EU countries have found banned pigments and non-compliant inks still being sold after REACH restrictions — a supply-chain and enforcement […]
Researchers are pairing lasers with acoustic methods (photoacoustic monitoring and acoustic shock/ultrasound) to both improve tattoo-pigment fragmentation and provide real-time feedback on treatment efficacy. Photoacoustic […]
To create immutable records for pigment origin, lab analyses, and conformity certificates, some outfits are piloting supply-chain traceability using blockchain ledgers (analogy: food and luxury-goods […]
Japanese researchers unveiled a tattoo-like patch inked onto the skin that changes hue when cortisol levels rise, offering a visual stress indicator. This could benefit […]
NASA has begun early testing of inks that fluoresce in response to cosmic radiation, intended to give astronauts a visual warning of exposure during long […]
Scientists have created a bio-adaptive ink that expands with cell growth, maintaining shape and clarity as the skin stretches or regenerates. This breakthrough may prevent […]
Emergency medicine teams are increasingly recommending UV-reactive inks for medical alert tattoos (like allergies or chronic conditions). These tattoos remain invisible under normal light but […]
