Article Synopsis
- - Photobiomodulation therapy using micro light-emitting diodes (µLEDs) shows great promise for anti-aging treatments in the beauty industry, particularly through a specially designed face mask.
- - The innovative face-fit µLED mask features a 3D origami design that conforms closely to facial contours, allowing for effective deep tissue light treatment and precise µLED transfer at high speeds.
- - Clinical trials indicate that the µLED mask significantly improves skin issues like elasticity, sagging, and wrinkles, achieving up to a 340% increase in elasticity in the perioral area compared to conventional LED masks.
Transfer printing of inorganic thin-film semiconductors has attracted considerable attention to realize high-performance soft electronics on unusual substrates. However, conventional transfer technologies including elastomeric transfer printing, laser-assisted transfer, and electrostatic transfer still have challenging issues such as stamp reusability, additional adhesives, and device damage. Here, a micro-vacuum assisted selective transfer is reported to assemble micro-sized inorganic semiconductors onto unconventional substrates.
