Muscle function loss can result from multiple nervous system diseases including spinal cord injury (SCI), stroke, and sclerosis (MS). Electrical muscle stimulation is clinically employed for rehabilitative therapeutic purpose typically requires mA-level current. Here, we report electrical stimulation, which directly powered by a stacked-layer triboelectric nanogenerator (TENG) through flexible multiple-channel intramuscular electrode. This electrode allows mapping of motoneurons that sparsely distributed in the tissue thus enables high efficiency TENG although short-circuit current only 35 μA. With matrix, find affected two factors, namely, electrode-motoneuron position, waveform polarity. To test whether it universal phenomenon then further investigate with conventional square wave confirm also these factors. Thus, develop self-powered direct as power source generator, to allow motoneuron optimization. We believe such could be potentially used treat loss.

With the rapid advances in wearable electronics and photonics, self-sustainable systems are desired to increase service life reduce maintenance frequency. Triboelectric technology stands out as a promising versatile due its flexibility, self-sustainability, broad material availability, low cost, good scalability. Various triboelectric–human–machine interfaces (THMIs) have been developed including interactive gloves, eye blinking/body motion-triggered interfaces, voice/breath monitors, self-induced wireless interfaces. Nonetheless, THMIs conventionally use electrical readout produce pulse-like signals transient charge flows, leading unstable lossy transfer of interaction information. To address this issue, we propose strategy by equipping with robust nanophotonic aluminum nitride (AlN) modulators for readout. The electrically capacitive nature AlN enables work open-circuit condition negligible flows. Meanwhile, information is transduced from THMIs' voltage modulators' optical output via electro-optic Pockels effect. Thanks flow high-speed carrier, stable, information-lossless, real-time achieved. Leveraging design flexibility circuits, various linear sensitivities independent force speeds achieved different ranges. Toward practical applications, develop smart glove realize continuous robotics control virtual/augmented reality interaction. Our demonstrates generic approach developing HMIs features systems.
