Driven by rapid advances in the thermoelectric (TE) performance of organic materials, conjugated polymer thermoelectric (PTE) materials are considered ideal candidates for flexible self-powered devices because of their intrinsic flexibility, tailored molecular structure, large-area solution processability, and low thermal conductivity. One promising application is the flexible and wearable TE devices used on the human body to convert human energy (human motion or body heat) into electricity. The self-powered character with extended functions allows PTE devices to monitor human activity or health status. In this review, we first introduce existing high-performance PTE materials and the architectures of PTE devices. Then, we focus on the progress of research on flexible self-powered devices based on PTE materials, including TE generators, TE sensors, and Peltier coolers. Finally, possible challenges in the development of PTE devices are discussed.

The development tendency of “More than Display” is proposed for the display and semiconductor technologies, and the new-brand architecture of heterogeneous integration system in display (HiSID) is established in accordance with the demands of third generation Micro/Mini-LED devices. Many functional units (e.g., display units, storage units, sensing units, communication units and computing units) are integrated into one display main-board based on the semiconductor technology and electronic packaging. The advantages and details of miniaturization, intelligent, advanced integration, signal integrity with low latency performance, process compatibility and reliability are introduced. The interconnection requirements and design of the HiSID model with artificial intelligence are also summarized in this paper. It will provide technical guidance and references for the commercial application, core technology, and breakthrough direction of the HiSID module in display technology.

Expanding the metal-semiconductor-metal (MSM) structure to encompass a broader range of passive networks is crucial for enhancing the understanding of carrier transport theory and broadening its application scope. Here, a mechanism to modulate the Schottky barrier using mechanical friction is proposed to generate electricity. The findings reveal that contact electrification occurs between the MSM structure and the friction medium, leading to charge redistribution within the system and the application of a bias voltage across the Schottky barrier via a conductive bridge. The conductive friction medium, whether liquid or solid, functions analogously to a conventional physical bias in a Schottky barrier diode, enabling the efficient regulation of the carriers. Aligning the electronegativity of the friction medium with that of the MSM structure, in accordance with the triboelectric sequence, enables the Schottky MSM structure to switch between AC and DC outputs, further validating the proposed carrier transport mechanism. Additionally, we showcase a constant generator composed of a parallel diode array to harvest energy from droplets excitation and the generation of a control signal through solid friction. This work advances the theoretical understanding of the Schottky MSM structure driven by mechanical friction and highlights its potential applications in passive networks.
