Compact wireless light sources are a fundamental building block for applications ranging from wireless displays to optical implants. However, their realization remains challenging due to constraints in miniaturization and the integration of power harvesting and light-emission technologies. Here, we introduce a new strategy for a compact wirelessly powered light-source that consists of a magnetoelectric (ME) transducer serving as power source and substrate and an anti-parallel pair of custom-designed organic light-emitting diodes (OLEDs). The devices operate at low frequency AC magnetic fields (~100 kHz), which has the added benefit of allowing operation multiple centimeters deep inside watery environments. By tuning the device resonance frequency, it is possible to separately address multiple devices, e.g., to produce light of distinct colors, address individual display pixels, or for clustered operation. By simultaneously offering small size, individual addressing and compatibility with challenging environments, our devices pave the way for a multitude of applications in wireless displays, deep tissue treatment, sensing, and imaging.
