Taopatch

Coin-sized adhesive disc its maker says turns body heat into light signals

Made by the Italian firm Tao Technologies, the patch is a small disc taped to the skin. The company says nanocrystals inside convert body heat into weak light aimed at the nervous system, and markets it for pain, posture and balance. Doctors who have looked at that explanation call it unsupported, and the studies behind it are small, financed by the firm and published in minor journals.

    Photographed in 2023 with a small metal disc taped to his chest, he said it was a Taopatch from Tao Technologies, and Tennis365 reports his claim that the patch is the biggest secret of his career. The same piece quotes a pseudoscience debunker calling the mechanism unbelievable and a neurologist calling the device unproven, and says the supporting studies are small and paid for by the firm.
