An article comprising a heater that comprises a high-resistance magnification (HRM) PTC ink deposited on a flexible substrate to form one or more resistors. The HRM PTC ink has a resistance magnification of at least 20 in a temperature range of at least 20 degrees Celsius above a switching temperature of the ink, the resistance magnification being defined as a ratio between a resistance of the double-resin ink at a temperature ‘T’ and a resistance of the double-resin ink at 25 degrees Celsius.

This document describes techniques and apparatuses for connecting an electronic component to an interactive textile. Loose conductive threads of the interactive textile are collected and organized into a ribbon with a pitch that matches a corresponding pitch of connection points of the electronic component. Next, non-conductive material of the conductive threads of the ribbon are stripped to expose the conductive wires of the conductive threads. After stripping the non-conductive material from the conductive threads of the ribbon, the connection points of the electronic component are bonded to the conductive wires of the ribbon. The conductive threads proximate the ribbon are then sealed using a UV-curable or heat-curable epoxy, and the electronic component and the ribbon are encapsulated to the interactive textile with a water-resistant material, such as plastic or polymer.

A wiring board is provided with: an insulating layer; a base electrode layer layered on one primary surface of the insulating layer in predetermined regions; an insulating covering layer layered on one primary surface of the insulating layer in a state covering parts of edges of the base electrode layer; and a surface electrode layer plated on exposed portions of the base electrode layer not covered by the insulating covering layer, the thickness of covered portions of the base electrode layer covered by the insulating covering layer being less than the thickness of the exposed portions. The surface electrode layer is formed only on the exposed portions of the base electrode layer.

Embodiments disclosed herein provide approaches for attaching scan control and other electronic chips to textiles, e.g., on a loom as part of a real-time manufacturing process.

Described herein are triboelectric energy generators that generally include a first flexible layer having a first electron donating material coated on at least a first surface and an electron accepting material coated over the first electron donating material, and a second flexible layer having a second electron donating material coated on at least a first surface. The first and second layers are positioned adjacent each other with their first surfaces facing inward toward each other and separated by a gap distance. An electric potential is generated upon movement between the first and second flexible layers, such as at least alternating contact and no-contact between the first and second flexible layers. The electron donating material may be provided by a particle-free conductive ink.

A flexible and/or stretchable structural system for transmitting electrical signal between first and second rigid portions comprises a body structure and said first and second portions arranged to said body structure. The modulus of elasticity of said first portion is lower than the corresponding modulus of elasticity of said second portion. In addition the modulus of elasticity of said body structure is lower than the corresponding modulus of elasticity of said second portion. The system comprises also an interface portion, such as e.g. an electrically conducting fabric, textile or knit, which is arranged to said body structure and between said first and second portions. The interface portion electrically connects said first and second portions. The modulus of elasticity of said interface portion is lower than the corresponding modulus of elasticity of said second portion.

The core-shell structured fiber-type strain sensor of the present disclosure, which includes a fibrous support forming a core and a multilayered shell layer formed on the fibrous support, exhibits improved strength and stiffness due to the core fiber, exhibits improved noise level due to an elastomer layer and allows manufacturing of a fiber-type sensor with improved linearity of measurement signals due to a sandwich-structured conductive layer, is advantageous in that stable strain measurement is possible without acting as a defect in a composite structure.
