Interconnect–chip and substrate–component junctions. Classification centers on connecting and assembling functional components.

Device integration and packaging

Connecting different materials and components involves more than electrical contact. A junction may also need to tolerate deformation, provide insulation and protect the device. This theme covers chip-to-soft-circuit connections, sensor-system assembly and encapsulation, alongside related materials and device-physics research.

d-HAPT: hydrogel-based joining of different materials uses a dried PVA/tannic acid adhesive layer to join metals, polymers and hydrogels. Its evidence concerns material adhesion and the stability of assembled devices under deformation; fine-pitch IC interconnection requires a separate evaluation.

The review on packaging rigid IC chips into deformable circuits compares prior work through adhesion, electrical junction stability and deformation tolerance. Read maximum strain separately from cyclic loading, alongside short circuits, open circuits and junction fatigue at closely spaced contacts.

MOLE: insulating encapsulation and an antifouling outer interface combines bonded silicone/Parylene C layers for mechanical integrity and moisture protection with a lubricant-infused surface. Accelerated tests at 85 °C and seven-day mouse subcutaneous implantation address different questions; they do not establish long-term implant lifetime or clinical benefit.

Hydrogel-based anisotropic conductive film (H-ACF)

H-ACF is documented in a public presentation at the 2023 MRS Spring Meeting. It is identified here as conference material. Until a corresponding peer-reviewed journal DOI is verified, it is kept separate from the publication list below and is not treated as established IC-junction reliability evidence.

Mechanically Robust and Anti‐Biofouling Hybrid Encapsulation via Layered Organic–Liquid Interfaces for Implantable Devices

Small, 22(17), e10949 (2026)

Device integration and packagingJoining and protective packaging

MOLE combines bonded silicone–Parylene C layers with a lubricated surface. Insulation was tested by accelerated aging at 85 °C, and device degradation and tissue responses by 7-day subcutaneous implantation in mice; these results do not establish a long-term human implant lifetime.

Device integration and packagingComponent assembly and fabrication

d-HAPT joins dissimilar electronic materials through moisture-induced chain entanglement in dried PVA–tannic acid layers. Dry–dry bonding uses interfacial water and heat; wet–dry bonding uses hydrogel moisture. Wet–wet and dry-material–tissue adhesion remain limited.
