Research of Joining Brittle Nonmetallic Materials with an Active Solder
Advances in Materials Science and Engineering, 2014 This paper deals with soldering high-purity brittle, nonmetallic materials such as SiO2, Si, and C (graphite). However, these materials exert poor wettability when using tin solder. Therefore, to reduce the wetting angle, an Sn solder alloyed with active

Microscale 3D‐Printed Digital Strain Switches for Embedded Mechanical Computation
Advanced Materials Technologies, EarlyView.Microscale 3D‐printed strain switches on flexible films convert deformation into native digital signals at geometry defined thresholds. A closed form model predicts switching from 3000 to 15 000 microstrain and is validated across 110 devices. Reliable ohmic closure and strain activated AND, OR, and XOR logic point toward low‐power mechanical ...
