Multifunctional Sensors and E-Skin based on Thermosensation

【Abstract】

Although wearable electronic technology has achieved significant progress, challenges still exist in multifunctional integration, simple fabrication, and low-cost applications. Human skin is a smart sensory system with multi-sensations via its thermoreceptors and mechanoreceptors. Unlike the public attentions on the mechanoreceptors, we focus on the thermoreceptor because of its unique multifunction. Thermosensation of human skin responds to not only temperature stimuli, but also thermal conductivity of touched material. In addition, the thermosensation also responds to wind flow because the flow takes away the heat from skin. These delicate sensations enrich human interactions with environment. Inspired by the thermoreceptor of human skin, we propose a new sensing principle based on thermosensation and utilize thin-film thermistors fabricated on flexible polyimide to implement multifunctional integration of pressure, proximity, matter, temperature, flow, slip, and texture sensing into flexible sensors and electronic skin (e-skin). These sensors and e-skin have the merits of high integration, simple structure, low cost, and good adjustability. We apply the flexible sensors and electronic skin to healthcare and intelligent robots, and combine artificial intelligence to realize human physiological monitoring, wearable limb motion capture, robotic garbage sorting, smart home services and other applications.

柔性电子技术已经取得了引人瞩目的发展，但在多功能集成、简单制造和低成本应用方面仍存在挑战。人体皮肤是由热感受器和机械感受器组成的具有多种感觉的智能感知系统。与机械感受器不同，热感受器具有独特的多功能性。人体皮肤利用热感应不仅对温度刺激有反应，而且对接触材料的导热性亦有感应，皮肤也会感觉到风，这是由于气流带走皮肤的热量，丰富的热感觉为人类与外界环境的交互提供了信息保障。受皮肤热感受器启发，我们提出了全新的热感应多模传感原理，利用柔性热敏薄膜与外界传导/对流换热对自身电阻的调控，实现了压力、接近、物质、温度、流量、滑动、纹理等多维信息感知的柔性传感器和多功能电子皮肤，具有高集成、简结构、低成本、易调控的特点。我们将柔性传感器和电子皮肤应用于医疗健康和智能机器人，结合人工智能技术，实现了脉搏/血压/呼吸等生理监测，可穿戴肢体运动捕捉，机器人垃圾分拣、智能家庭服务等应用。

Design and Fabrication of Flexible Sensors for Robotic Tactile Sensing

【ABSTRACT】

Haptic perception is the most challenging perception technology in robotic systems, which is of great significance for robots. In recent years, based on the coupling of triboelectricity and semiconductors, tribotronic electronics have established a direct interaction mechanism between the external environment and the electronics. Compared with traditional tactile sensing methods such as piezoresistive, capacitive, and piezoelectric, tribotronic devices have the advantages of active, low power consumption, wide choice of materials, proximity sensing, and weak triggering response, which brings new opportunities for the development of robotic tactile sensing technology. We are committed to the design and manufacture of flexible sensors for robot tactile sensing application research. In terms of sensing principle, we have verified that tribotronic devices can theoretically achieve a spatial resolution of up to 20 nm for tactile sensing by establishing a nano-scale tribotronic transistor model. In terms of structural design, high-performance proximity and contact sensing is realized through the design of floating gate structures. In terms of fabrication, the consistency and stability of device performance are improved by combining the traditional micro-nano-machining process and the new flexible electronic process. In terms of integration and application, a high-performance haptic sensing feedback closed-loop system has been constructed, and experimental verification of typical dexterous operations such as robotic grasping has been completed.

Material and Device Designs in Biomimetic Polymer Electronics

【ABSTRACT】

This talk will highlight the latest advancements in haptic intelligence. Tactile sensors, which transform mechanical stimuli from touch-based physical interactions into electrical signals, have become increasingly vital in the rapidly evolving field of robotics. The rocketing development of artificial intelligence necessitates more sophisticated capabilities for the acquisition of precise tactile information. Active sensing technology based on the principle of triboelectricity offers a new approach to achieving high-performance tactile sensors, demonstrating significant advantages in interface sensitivity and dynamic response. In this talk, we will primarily introduce triboelectric tactile sensors. A focus will be placed on well-engineered triboelectric tactile sensor in single-electrode and non-gap contact-separation structures, which has shown remarkable capabilities of surface material identification, ultra-fast response and Shore hardness measurement. We will also introduce developments in hybridized tactile sensors designed for multifunctional tactile sensing. The integration of triboelectrification-based active sensor with typical tactile sensor (such as piezoresistive, capacitive and inductive transducers) enables the simultaneous measurement of multiple information about the objects being held and facilitating object identification. Additionally, this integration aids in the precise acquiring of static and dynamic mechanical stimuli. Intelligent robotic tactile applications realized through multiparametric tactile sensors with the aid of machine learning will be discussed as well.
