Alopecia is considered an aesthetic, psychological, and social issue among modern people. Although laser-induced skin stimulation is utilized for depilation treatment, such treatment has significant drawbacks of high energy consumption, huge equipment size, and limited usage in daily life. Here, we present a wearable photostimulator for hair-growth applications using high-performance flexible red vertical light-emitting diodes (f-VLEDs). Flexible microscale LEDs were effectively fabricated by a simple monolithic fabrication process, resulting in high light output (∼30 mW mm^–2), low forward voltage (∼2.8 V), and excellent flexibility for wearable biostimulation. Finally, trichogenic stimulation of a hairless mouse was achieved using high-performance red f-VLEDs with high thermal stability, device uniformity, and mechanical durability.

使用单片柔性垂直AlGaInP发光二极管的致发光刺激

脱发症被认为是现代人的审美，心理和社会问题。尽管将激光诱导的皮肤刺激用于脱毛治疗，但是这种治疗具有明显的缺点，即高能耗，巨大的设备尺寸以及日常生活中的使用受限。在这里，我们介绍了一种使用高性能柔性红色垂直发光二极管（f-VLED）的用于头发生长应用的可穿戴光刺激器。柔性微型LED通过简单的整体制造工艺进行了有效制造，从而产生了高光输出（〜30 mW mm ^–2），低正向电压（〜2.8 V）以及可穿戴生物刺激的出色柔韧性。最终，使用具有高热稳定性，设备均匀性和机械耐久性的高性能红色f-VLED实现了无毛小鼠的毛发刺激。
