Abstract: Abstract Thermoelectric (TE) ionogel have emerged as promising materials for harvesting low-grade heat owing to their flexibility and giant thermopower. However, current high-performance TE ionogel requires multi-component systems, resulting in trade-offs between TE performance, mechanics, and ion leakage risk. Moreover, the humidity-dependent thermopower and two-dimensional device architectures restrict their practical applications. Here, a thermally actuated TE ionogel fiber is designed by tailoring the interactions between liquid crystal elastomer (LCE) network and ionic liquid. Fine tuning the mesogen orientation of LCE network ensures ~3-fold thermopower boost (25.8 mV K−1) and ~30-fold electrical conductivity boom (21.5 mS m−1) at low humidity (
