Fabric-substrated capacitive biopotential sensors enhanced by dielectric nanoparticles

Wearable biopotential sensing devices are essential to long-term and real-time monitoring of human health. Non-contact, capacitive electrodes prevent potential skin irritations, thus beneficial for monitoring. Existing either connected a separate control circuit via external wires or have limited capacitances, which leads low signal qualities. This study demonstrates stretchable device with integrated electronics, enhanced The the electronics fabricated on common fabric substrate breathability strain-limiting protection. based an island-bridge design stretchability as high ? 100%, area ratio 80%. By using dielectric calcium copper titanate (CCTO) composite adhesive layer, electrode capacitance can be increased, yielding signal-to-noise (SNR) in acquired biopotentials. offers convenient comfortable approach non-contact signals.
