A high‐output large‐area lead zirconate titanate (PZT)‐based nanocomposite generator (NCG) device is demonstrated using a simple, low‐cost, and scalable bar‐coating method. The generated output reaches up to ≈100 V and ≈10 μA and powers 12 commercial light‐emitting diodes (LEDs) without external energy‐storage systems. This demonstrates the feasibility of using NCG devices to power consumer electronics, self‐powered devices, and wireless sensor networks using irregular mechanical agitation.
