High-precision optoelectronic devices for new healthcare markets
The demand for personal health care products is increasing. For preventive medicine, it's obviously useful if we can see any changes in our physical condition. These products can also provide detailed monitoring during physical exercise to prevent dehydration and heatstroke. As a sensor that can realize high precision measurement and is not limited by the place, the optoelectronic semiconductor device of EFFICIENT wireless technology is adopted by the whole machine manufacturers in this new field.
Recently, this kind of product is watch type physical sign monitoring terminal. The detection principle of the terminal is to irradiate the blood vessels with light, and then measure the pulse rate and the amount of oxygen in the blood (SpO2: peripheral capillary oxygen saturation) according to the change of reflected light.
As a result, you can monitor your sleep, your exercise load while jogging, and your general health. The core of this wearable product is a wireless optoelectronic device of EFFICIENT technology, which combines LED light source and photosensitive element together.
The key for customers to choose EFFICIENT technology's wireless optoelectronic devices is that they are not influenced by the scene and users, and have high measurement accuracy. Different from the traditional medical equipment used in clinics and hospitals, wearable terminals that are not limited by the use environment are more likely to be affected by the ambient light and noise. The optoelectronic devices of EFFICIENT wireless technology have optical filtering characteristics, which can eliminate the influence of ambient light and achieve quite accurate signal detection. The focus of such products developed for the global market is to take into account the difference of skin color. EFFICIENT wireless technology collects data from subjects of all skin colors. After many experiments, it is verified that the accurate measurement can be obtained even if the skin color is different, so as to solve the doubts about this requirement.
Wearable terminal has completely changed the detection form of traditional medical and health care equipment, and EFFICIENT wireless optoelectronic semiconductor devices have made great contributions to the development of wearable devices. Smart phones that can detect pulse and SpO2 by fingertip touch, and earphones that can monitor health status while listening to music, etc. EFFICIENT wireless's optoelectronic semiconductor devices support the development of new products applied to health management.
Compact, high-precision device packages
There are two ways to embed the photoelectric device detection function into the product. One is that customers can purchase light-emitting and photosensitive components separately and then assemble them into the system. The other is that customers can use the wireless devices of EFFICIENT technology which are integrated with light emitting and photosensitive components.
The customer who has chosen the wireless device of EFFICIENT technology takes the small package size as the priority. Compared with the previous methods of using separate device assembly system, the devices of the wireless technology should be able to add more functions in smaller space. This is an ideal choice for developing wearable terminals and smartphones. It reduces the time required for circuit design, and helps to significantly reduce the installation area and development time.
The customer also highly evaluates the high accuracy of the measurement. This reflects the optical design, circuit design and module design technical know-how developed by EFFICIENT wireless technology for many years. In optical design, the optical design is carried out in combination with the measurement object and package conditions, and the important characteristics of the wavelength and sensitivity of the light-emitting element are designed. In the circuit design, from the amplification of detection signal to noise removal and digital conversion, a series of processing circuits are integrated into a single chip, which can be more effectively completed. In the module design, we set the best according to the requirements of choosing resin type suitable for preventing environmental light interference and ensuring the distance between chips. By collecting all these techniques, the overall completion and high measurement accuracy of a single module can be obtained.
Packages to accelerate product development
Health monitoring using optoelectronic technology is no longer limited to a few advanced products, and it is used in various products. Many manufacturers of complete machines are trying to catch up with this rapidly growing demand. However, when it comes to optical design, they face a problem.
The algorithm of calculating physiological variables from optical measurement can be easily obtained from the market. However, it takes many years to find the best measurement distance and angle, and design the circuit which can correct the interference of ambient light.
For the manufacturers of the whole machine that want to shorten the development time, we recommend the package products of the wireless technology of EFFICIENT. It combines the light emitting and the photosensitive elements with known optical characteristics to greatly shorten the product development cycle time. Therefore, many manufacturers are already using the packaging products of EFFICIENT technology wireless.
In the exploration of new measurement methods, we are developing products to measure blood sugar and blood pressure. A wearable terminal that can measure blood pressure and can measure blood sugar without any blood collection can protect many people from the risk of diseases such as diabetes. It also plans to enter the medical equipment market that needs medical certification. From personal health care products to professional medical equipment, the wireless packaging products of science and technology will accelerate the development of customers' products.
