Abstract

Harvesting the low-grade heat energy from the environment and the human body remains an underutilized energy. Ionic thermoelectric (i-TE) gels have garnered significant attention in the fields of energy harvesting and sensing due to their exceptional stretchability, adaptability, ease of large-scale fabrication, and excellent thermoelectric performance. This review aims to provide a comprehensive overview of the recent progress of i-TE gels in application of temperature sensing and low-grade heat energy harvesting. The narration begins with the introduction of the synthetic and natural polymer for i-TE gels. Then, various methods are discussed to enhance the mechanical performance (stretchability, self-healing, and mechanical durability) to satisfy the flexible device based on i-TE gels. Noticeably, this work emphatically summarizes the improvement methods of thermopower for i-TE gels, including the preparation of n-type i-TE gels and the bidirectional modulation of their thermopower. Finally, this work explores the diverse applications of i-TE gels, including low-grade heat harvesting, sensing, human-machine interfaces, and biomedical applications.

用于低品位热能收集和热传感的离子凝胶。

从环境和人体中收集的低品位热能仍然是一种未被充分利用的能源。离子热电（i-TE）凝胶由于其优异的可拉伸性、适应性、易于大规模制造和优异的热电性能，在能量收集和传感领域受到了极大的关注。本文综述了i-TE凝胶在温度传感和低品位热能收集方面的最新进展。首先介绍了i-TE凝胶的合成和天然聚合物。然后，讨论了各种提高机械性能（拉伸性、自愈性和机械耐久性）的方法，以满足基于i-TE凝胶的柔性装置。值得注意的是，本文着重总结了i-TE凝胶热功率的改进方法，包括n型i-TE凝胶的制备和热功率的双向调制。最后，本研究探讨了i-TE凝胶的各种应用，包括低品位的热收集、传感、人机界面和生物医学应用。
