Embodiment Construction

[0024] The invention improves and solves the problem that the disabled cannot obtain the sense of touch when using artificial limbs. At present, most of the smart skins used in the world are surgically implanted with subcutaneous chips, which convert the changes of pressure, temperature or humidity on the surface of the attached smart skin into electrical signals and transmit them to the nerves, thereby generating sensation. However, these technologies are still very immature. Most of the skin can only transmit a certain kind of sensory changes, and the current subcutaneous implantation operation is extremely risky and expensive. At the same time, it is extremely difficult to replace the chip if it is damaged or falls off. The problem. Therefore, it is particularly necessary to design an external sensory skin to help users produce sensations before the implantable chip is mature. upgrade.

Abstract

The invention discloses a wearable device for transferring sensations. Multiple thin-film pressure sensors and semiconductor temperature sensors are mainly used to sense changes of an external environment and convert the changes into pressure control signals and temperature control signals, a master controller controls stepping motors to drive sliders to slide up and down to produce a pressure sense, meanwhile, a PTC heating module is arranged at the ends, making contact with limbs, of the sliders to produce corresponding temperatures. In order to prevent the condition that the heating temperature is too high or circuit failures lead to heating all the time, the PTC heating modules have an automatic power off function and can automatically power off to guarantee safety once the power-on time exceeds a given value.

Description

technical field [0001] The invention belongs to the technical field of sensory feedback and relates to a wearable device for transmitting sensory feedback. Background technique [0002] At present, smart skin is used to solve the problem that the disabled cannot obtain the sense of touch when using artificial limbs. However, all existing smart skins use sensors to sense changes in external conditions and then generate corresponding stimuli that directly act on the user's nerves to generate sensation. The prerequisites It is necessary to implant sensory chips on the nerves, but this process is very dangerous, the success rate is extremely low, and the price is expensive. At the same time, it faces the problem that it is extremely difficult to replace the chip if it is damaged or falls off. At this stage, no skin has been put into the market, and the feasibility is only verified under laboratory conditions. There is still a long time before its real commercialization, and how ...
