  • Publication number: 20240402006
    Abstract: A flexible ultraviolet sensor circuit is provided comprising a number of solar cells, a reflective display device electrically connected to the solar cells, and a floating gate transistor electrically connected to the solar cells and reflective display device. A floating gate in the floating gate transistor discharges in response to ultraviolet light such that the floating gate transistor turns on when a threshold voltage of the floating gate transistor drops below a combined open circuit voltage of the solar cells minus a switching threshold of the reflective display device, thereby causing electrical current flow through the ultraviolet sensor circuit. The reflective display device changes as the electrical current flow increases, indicating total ultraviolet light exposure.
