One of the very effective and creative methods for Photo-bio-modulation use has been discovered by Advanced Materials Technologies. This method includes a wearable patch directly applied in-vitro, on the skin. Clickhere to read more…
Wearable Photo-Bio-Modulation Device
With the precedent of a flexible infrared‐wavelength organic light‐emitting diode (OLED), a now wearable photo-bio-modulation patch for wound healing is shown by Kyoung‐Chan Park, Kyung Cheol Choi, and their co‐workers in the above link. This wearable, material device promotes in vitrowound and joint healing. Some of it’s important characteristics is that it is reliable during operation, flexible, and operates at a low‐temperature, so that it can be used in any location and time, attached to the human body. It has an operational time of more than 300hours!
Specifications of the device
‘Photo-bio-modulation (PBM) is a safe and noninvasive method that can provide various clinical effects. However, conventional PBM devices using point light sources, such as light‐emitting diodes and lasers have various disadvantages. These, such as low flexibility, relatively heavy weight, and nonuniform effects. We are now able to present a novel wearable PBM patch using a flexible red‐wavelength organic light‐emitting diode (OLED) surface light source, which can be attached to the human body as a personalised PBM platform. The palm‐sized wearable PBM patch can be very light (0.82 g) and thin (676 µm). It also has a reasonable operation life (>300 h), flexibility (20 mm bending radius), and low‐temperature operation (<40 °C), and it can provide wide and safe application irrespective of location and time. Fibroblasts, a major type of dermal cells, play a key role in the wound healing process. The results show that OLEDs may have excellent in vitro wound healing effects because they effectively stimulate fibroblast proliferation (over 58% of control) and enhance fibroblast migration (over 46% of control) under various conditions. For maximum effect, peak wavelength control is necessary to optimise cell proliferation and enhance in vitro wound healing effects.’
