Integrating Hard Silicon for High-Performance Soft Electronics via Geometry Engineering

• Geometry engineering transforms brittle crystalline silicon into flexible forms—from 3D bulk to 2D nanomembranes and 1D nanowires—enabling high-performance soft electronics. • Silicon nanowires, grown via VLS or IPSLS techniques, offer exceptional mechanical flexibility and electrical performance, making them ideal for wearable and implantable devices. • Si-based soft electronics show promise in sensors, nanoprobes, robotics, and brain-machine interfaces, bridging the gap between rigid semiconductors and flexible substrates. • Challenges remain in scalable fabrication, long-term stability, and integration, but future directions point toward fully flexible silicon-based systems for widespread adoption.
