Design and fabrication of densely packed, stretchable electronic systems based on SMNMs. (A) Disassembly diagram of the device system. The system contained 42 integrated circuits with lateral dimensions of ~11.2 mm × 10.1 mm and area coverage of ~110%. Sub-circuits were arranged and electrically connected through vertical vias, highlighted with dashed lines. (B) Process of integrating and encapsulating serpentine interconnects with bilayer network materials. (C) Photographs of the SMNM-based stretchable electronic system mounted on the index finger. (D) Deformation of the device system when pressed (~15%). (E) Demonstration of the functional characteristics of an SMNM-based electronic system, taking a proof-of-concept demonstration of a wireless mouse application as an example. Left: Raw signals of quaternions (q₀, q₁, q₂, and q₃) obtained from the device were processed to produce representative vital signs for gesture recognition. Right: Photo showing control of the Sokoban pushing box game through hand gesture recognition (i.e., moving up, down, left, and right) [134]. Copyright 2022, Science Advances.
