Air Plasma Somatic Sense Induction via Laser Radiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for inducing somatic senses, such as tactile or thermal sensations, without direct contact with an object or heat source pose risks of damage to biological tissues due to direct laser radiation, necessitating a solution that prevents harm while effectively generating these sensations.
Innovation Solution
A somatic sense induction system utilizing air plasma generated by radiating a laser in the air, which produces shock waves and electric fields that stimulate skin tissues without direct laser exposure, controlling parameters like energy intensity, pulse width, and beam diameter to induce state changes in the skin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a laser is directly radiated on the skin to induce somatic sense, then the somatic sense induction effect is enhanced, but the skin tissue may be damaged by burning
Solution Approach 1:
The patent introduces air plasma as an intermediary medium between the laser and the skin. The laser is radiated into the air to generate air plasma, which then emits light and energy that stimulates the skin to produce somatic sensations. This mediator approach allows the laser energy to be transmitted indirectly, avoiding direct laser-skin contact that causes burning while still achieving effective somatic sense induction through the plasma-generated energy.
2Reliability
If the laser energy intensity is increased to improve somatic sense induction, then the sensation effect is enhanced, but the risk of tissue damage increases
Solution Approach 1:
The patent utilizes parameter changes in the air plasma state to control the energy transmission. By adjusting laser parameters (wavelength, pulse duration, energy density) and controlling the plasma generation conditions, the system optimizes the energy intensity reaching the skin. The air plasma acts as a buffer that transforms the laser parameters into a safer energy form for skin stimulation, maintaining effectiveness while reducing damage risk.
