Extended Data Fig. 2: Basic properties of the optoelectronic capsule used in this study.

(a) The composition and the whole size of optoelectronic capsule. (b) The user interface of the APP on smartphone for recording photocurrent signal. (c) The irradiating characterization of LED loaded in the optoelectronic capsule during 36 h. (d) The processing of raw photocurrent data through a sliding average filtering algorithm for smooth output when the optoelectronic capsule was placed under different conditions of luminescence Source data.
