Description

Amphibious intelligent data glove and preparation method thereof

Technical Field

The invention belongs to the field of intelligent equipment, and particularly relates to amphibious intelligent data gloves and a preparation method thereof.

Background

Under the influence of new crown epidemics, direct physical interaction between people is limited to prevent the spread of viruses, creating the need for non-contact control and mutual explosiveness. Thanks to artificial intelligence AI and 5G technologies, artificial intelligence oriented human machine interfaces (hmi) provide a human with the ability to remotely data with a machine or other people. Generally speaking, the hmi is a multifunctional electromechanical system that collects and transmits human motion information to a central processing unit, and the machine will then perform the appropriate function corresponding to the instruction.

The machine vision-based method is an important approach for acquiring human physiological information, but the key point is a proper optical environment. On one hand, the real-time recognition of the fine movements of the fingers is difficult to realize due to the shielding and shadowing effects of light, and on the other hand, the realization and operation of the system is costly and consumes much power. More importantly, in a water environment, machine vision based hand decoding does not perform well due to poor system water resistance and poor water transparency.

The wearable electronic device can directly acquire in situ characterization somatosensory signals which are insensitive to environmental conditions, wherein the sensor-based data glove is a perfect carrier for realizing hmi. At present, many strain sensors based on liquid metals, conductive polymers and triboelectric materials have been reported, but some problems are faced with devices that are incorporated into textile and hybrid power systems: 1) for liquid metal based strain sensors, low initial resistance (a few ohms) and relatively low specification current usually require large supply current, resulting in large working power and even system working failure; the problem of connecting liquid metal to metal electrodes is challenging due to the phenomenon of alloying liquid metal with most metals. 2) Liquid metal-based or triboelectric strain sensors have low sensitivity and often require a back-end amplifier to amplify the electrical signal corresponding to the strain change, increasing the complexity of the system. 3) The compatibility of the polymer strain sensor and the textile is poor, the processing difficulty of the sensing module part is large, and the air permeability of the textile is seriously influenced.

Meanwhile, considering that the environment in daily activities is complex and unstable, such as raining, sweating, accidental falling into rivers and the like, the wearable fiber is difficult to avoid contacting with moisture, such as water, sweat and the like, and suffers unpredictable mechanical deformation and even damage. Therefore, not only high sensitivity but also water resistance and mechanical robustness are required for smart fibers. Encapsulation is a simple but effective way to increase mechanical robustness and water resistance compared to chemical modification, providing additional protection of the internal functional material from external physical or chemical damage.
