New spinning method embeds fibre circuits

SHANGHAI — Researchers at Donghua University have developed a spinning method that builds electronic circuits inside soft fibres, potentially overcoming fragile connections in wearable smart textiles.

The researchers say the fibres withstand repeated bending, stretching and standard machine washing, and can be woven or sewn into fabrics. The process combines fibre formation, component fabrication and electrical connections in one continuous step, rather than attaching separate electronic devices to a textile.
