Abstract: Triboluminescent materials that produce light emission in response to mechanical action attract significant interest due to their wide range of potential utilization for mechanoresponsive sensors, light emitting devices and stimuli-induced glowing fibers, dyes, particles, paste, and films, etc. Here, we would like to disclose a general method of generating triboluminescent polymer materials blended with wide range of luminophores that emit light in response to mechanical action emitting light in a wide range of spectrum. The light generation is achieved via a non-destructive method even in the absence of direct contact with the polymer (e.g. through the layer of another polymer). Biocompatible luminophores can be easily utilized. Light emission is also observed under dry air.
