Application and development of medical devices based on the principle of optoelectronics

Sep. 19, 2023

In an era of sophisticated medical technology and treatment, compared to decades of reliance on chemical means, people are now more inclined to physical, including the use of photonics to inhibit and treat some lesions. In recent years, due to the popularity and trust of the people, a large number of physical therapy means are not only used in general clinical medicine, but also widely used in the field of medical aesthetics.

Emerging Developments in the Optoelectronics Industry

The optoelectronics industry does not exist in an independent form, it is a combination of related infrastructure and a variety of related technologies combined with the diversification of the industry, in the optoelectronics industry supported by a number of industries, medical equipment, especially the development of the medical aesthetic industry, as well as is rapidly changing. Wearable medical devices utilize the experimental principle of optoelectronics, and are becoming more and more popular.

photoelectronic technology

Photoelectron is in the photoelectric effect due to radiation excitation and thus produce electrons, but it is still the essence of the metal plate of electrons, just when it corresponds to the concept of photons also formed the name of photoelectron. Photonics technology is a combination of photon technology and electronics technology into a new technology, involving optical display, optical storage, laser and other fields, is the core technology of the future information industry. It not only marks the modernization and maturation of the information industry, but also the application of optoelectronics in biomedical science is very important.

Definition of Spectrum

Usually we see the light is actually complex color light, when the complex color light according to dispersion spectroscopy, was scattered by different lengths or frequency size of multiple monochromatic light according to the size of the wavelength or frequency and once the arrangement of the pattern, that is, our common spectrum. Many experiments we can see the dispersed light, such as optical prisms, gratings and sunlight bubbles these can see the complex color light dispersion. The light seen by humans in this wavelength range of electromagnetic radiation spectrum is called visible light, in this region of the light wave wavelength is about 400 ~ 760nm.

Biophotonics in Modern Healthcare

In modern medicine, medical imaging technology accounts for a very large proportion also predicts that this fluorescence imaging technology plays an obvious role and makes a very big contribution to medicine. Precision optical instruments also play a great role in ophthalmology and dentistry. These instruments are mainly cameras, visual field instrument, optometry, intraocular pressure meter, corneal curvature meter, slit lamp microscope and so on.

X-ray applications

X-rays themselves are very penetrating, they are not visible to the naked eye but they can pass through a wide variety of solid materials. For example, intact bones appear milky white on photopolymer paper, while gaps between bones appear less milky or black. X-rays can also be used to detect other lesions, such as cavities in the lungs, destruction of bones, decayed bone in cavities, and narrowing of the trachea.
Fluorescence refers to a cold luminescent phenomenon of photoluminescence. Fluorescence, which is commonly used by dentists to detect dental caries, is the production of fluorescence by shining a light source on tissues such as the teeth or dental beds. When the light source irradiates the teeth of a caries patient and the teeth of a normal person, the fluorescence of different intensities will be obtained, and after software imaging, the degree of damage to the patient's teeth can be easily determined, as well as to determine the location of the disease, which greatly improves the efficiency of the medical staff and helps the patient to confirm the diagnosis in a timely manner. Fluorescence diagnosis is a non-damaging, non-contact and highly sensitive and diagnostic diagnostic method.

Thermal Imaging and Spectroscopy

Apart from visible light, infrared light is almost the most utilized category by mankind. This includes thermal imaging technology. A non-contact detector or camera detects infrared energy and heat through a temperature sensor and converts it into an electrical signal, which generates a thermal image and a temperature value on a display. Different colors indicate a range of temperature values, and this technology is used not only in some measurements, but also in the field of biology. We often see in the animal world that many zoologists want to carry out their research but are unable to observe the animal's habits at close range or at night, and this is where thermal imaging cameras are used to observe and record the temperature changes in various parts of the animal's body. Thermal imaging is mainly used for the detection and prevention of early onset tumors and cancerous lesions, as well as the detection of inflammation.

Medical treatment is now constantly working towards preventing diseases in this area. Scientists have implanted temperature sensors with great sensitivity into intimate apparel, and if the body has a tumor or cancerous lesion, the temperature sensors will convert the temperature into an electrical signal, which will be reflected by thermal imaging.

Spectroscopy is also applied to the detection of another pathology, arthritis. The project utilizes a halogen bulb with a spectral length of 1000nm or more, which is capable of achieving the required spectral length for the experiment, and concentrates the light through an integrating sphere to help penetrate human joints. Spectral analysis software was also utilized, which has powerful data processing capabilities and a clear graphical user interface for use with the micro-spectrometer. By placing the patient's diseased joint in the light exit of the integrating sphere and placing the spectrometer on the other side we can observe clear spectral fluctuations through the software, which also has powerful data processing capabilities and a clear graphical user interface as one of its advantages. When enough samples have been collected and analyzed by the algorithm, it is possible to detect arthritic lesions in human beings.

Laser Spot Removal

The human body suffers from sunburn, unbalanced secretion of substances in the body and other chemical reasons in the face will have spots appear, which is difficult for most women to accept, many people will choose medical cosmetic treatment to weaken these pigments such as laser removal of spots. The laser spot removal instrument can choose different types of lasers to act on different skin tissues according to the patient's skin type and skin tissues, and as long as a specific light source is used, the removal of pigmentation can be accomplished without causing damage to the surrounding skin and without affecting the normal skin tissues. The principle of laser spot removal is that high energy is absorbed by the pigment particles in the lesion in a very short period of time, generating extremely high temperature, and then the pigmented material expands rapidly and bursts, vaporizing and crushing into very small particles, and finally the macrophages in the immune system of the human body will devour and remove the smiled particles after bursting.

Cold Light Tooth Whitener

The cold light teeth whitening instrument is a high-intensity blue light (wavelength 480~520nm) through the multiple coating treatment on the optical lens, as a way to isolate all the harmful ultraviolet and infrared light. The whitening instrument will be worn on the teeth coated with a special whitening agent, through the irradiation of high-intensity blue light can help to remove tartar deposited over the years in a short period of time, but also deep cleaning oxidized substances to achieve the effect of removing the yellow and bright white.

High-intensity blue light produces a whitening effect that is not only used for teeth whitening, but is also commonly used for body whitening in many medical aesthetic treatments.

With our large population, the demand for optoelectronic products in healthcare and biotechnology will continue to grow steadily in the future. It is expected that optoelectronic products associated with this will also have strong development potential and space in the next 5 to 10 years.
