From: A wireless battery-free eye modulation patch for high myopia therapy
a Designs, operational features and use cases for wireless eye modulation patch. b Wireless charging based on ultrasound, adjustable micro-actuator for shortening the axial length (AXL) of the eye and improving vision to normal levels. c Under blue μ-LEDs irradiation, riboflavin promotes collagen cross-linking (SCXL) in scleral tissue, enhancing scleral strength. d Exploded view of the flexible eye modulation patch. Microneedle array (MN array). Piezoelectric transducer: lead zirconate titanate (PZT). e Integration of the corresponding subcomponents and optical image of the patch. Scale bar, 5 mm. a-anterior, p-posterior, n-nasal, t-temporal, s-superior, i-inferior.
