Abstract: An integrated system for textile hybrid electronics via laser hybrid manufacturing includes surface mounted devices (SMDs), laser-induced flexible sensors, a textile substrate, conductive textile traces and physiological electrodes, and vertical interconnect accesses (VIAs). By leveraging a material modification capability of a laser, patterned sensors can be prepared directly on the textile substrate. A precision cutting capability of a laser is utilized to create patterned flexible electrodes and interconnect wires. Furthermore, highly stable VIAs are formed by infiltrating the fabric's intrinsic structure with conductive composites. By integrating the aforementioned preparation techniques, a double-layer fabric circuit board can be realized on various daily-use and specialized textiles. Subsequently, the SMDs are soldered onto the board to form an integrated system for textile hybrid electronics.

Abstract: A textile electronic system for integrating muscle fatigue detection and treatment includes following components that are integrated on a textile substrate: conductive textile wires, physiological electrodes, vertical interconnect accesses (VIAs) and a surface-mounted device (SMD). The conductive textile wires are arranged on two sides of the textile substrate and communicated with each other through the VIAs, and an integrally formed circuit includes an electrode array and a signal conditioning circuit. The electrode array is configured for detecting an electromyography (EMG) signal and for applying electrical muscle stimulation (EMS), and the signal conditioning circuit is configured for EMG signal amplification, EMS waveform conditioning and overall timing logic control, and has functions of safety isolation and EMS waveform detection. The present disclosure can highly integrate components and devices on a single piece of textile through process design, and realize EMG signal collection and applying EMS.
