Abstract
A light transmission system is provided for operating an optically responsive circuit. The system includes a light guide film (LGF) to transmit light emitted from its edge, and a scattering node for directing the light to the circuit. The circuit is disposed on a proximate face of the LGF. The scattering node is disposed on a distal face of the LGF opposite the circuit. The circuit can be an integrated circuit, a light detection sensor or a photovoltaic cell.
Claims7
A wearable sensor device for optically responding to electromagnetic emission, said device being disposable on a body surface and comprising:
- a flexible light guide film (LGF) substrate having proximate and distal faces joined along an edge for receiving the emission to pass between said proximate and distal faces;
- an optically responsive switch disposed on said proximate face of said LGF substrate, said switch toggling upon receipt of the emission;
- and
- a scattering node disposed on said distal face of said LGF substrate opposite said switch for redirecting the emission to said switch.
