On September 17, 2020, the online seminar on “How wearable devices contribute to the development of health monitoring” held by Anfuli was successfully held. Experts from Osram and Ansemy Semiconductor attended the seminar, explained and discussed the development process and the latest technical solutions of wearable devices in the field of health monitoring, and shared cases.
Next, please review the highlights and dry goods brought by this seminar with OFweek.
OSRAM photoelectric sensor – wearable life state monitoring eyes
Wang Yaqin, head of the Asia-Pacific market department of OSRAM infrared and sensor, took the lead in introducing OSRAM photoelectric sensor and wearable device solutions. Wang Yaqin believes that the photoelectric sensor can help the device collect the user’s physical information, so it can also be compared to the wearable eye for life state monitoring. The concept of “wearable” is very broad. At present, the wearable devices that people talk about most are mainly smart bracelets, smart watches, smart earphones, VR/AR devices, in addition to skin patches, electronic fabrics, etc., with a variety of application fields. Due to the diversity of its functional requirements, the types of sensors used on wearable devices are also different. In addition to photoelectric sensors, there are GPS, temperature sensors, gyroscopes, accelerometers, chemical and gas composition sensors, etc.

Wang Yaqin said that from the birth of the first generation of wearable products in 2012 to the present, the market development has entered a recovery period of steady climb, especially in the medical and health market. Technology giants have invested in wearable devices, and smart bracelets and smart watches have started to be equipped with health monitoring function as standard. The “new” wear mentioned today not only has the functions of the original traditional wear products, but also can realize the test of medical level and more indicators detection, with sufficient accuracy, which can be used for medical guidance. In addition, wearable life state monitoring can track users’ data indicators for a long time, which is more meaningful for judging and predicting physical health, compared with the data under the single time cross section of traditional physical examination indicators. Combined with big data and artificial intelligence technology, wearable devices have higher ability of cross-comparison and data interpretation of different life indicators, which has helped people to complete health level assessment, stress level assessment, sleep quality assessment, emotional analysis and other aspects.
Wang Yaqin also introduced Osram’s life state monitoring product series in detail, including CT DBLP31.12 developed for wearable heart rate testing, SFH 7016 developed for life state monitoring, SFH 7015 for blood oxygen testing, and signal receiving PD, blue-green enhanced PD SFH2201, infrared filter PD SFH 2240, rectangular PD SFH 2703, small package PD SFH 2704, and semi-integrated module SFH 7072. After the speech, Wang Yaqin also answered questions about sensor packaging technology, monitoring accuracy and technical difficulties in product development.
Ansemy Semiconductor Yang Xuefang: Introduction to wearable medical product hardware solutions
Next, Yang Xuefang, senior application engineer of Ansemy Semiconductor, introduced the hardware solution of Ansemy Semiconductor wearable medical products. It is reported that Ansemy Semiconductor focuses on providing innovative medical solutions in implant, hearing health, clinical and consumer, and medical imaging. Yang Xuefang also brought successful cases of portable ECG, continuous blood glucose monitoring (CGM), heart rate monitoring (HRM) and implantable medical treatment. According to Yang Xuefang, Ansemy Semiconductor can provide a variety of wearable medical product solutions, and has many years of experience and rich IP in wearable medical solutions. In addition, Ansemy Semiconductor is in the world’s leading position in the research and development of hearing aid chips, Highly integrated chip solutions can accelerate customer design.

In the current application of wearable medical products, it is not only necessary to meet the requirements of consumer and medical applications, but also has high requirements for space. It also has strict requirements for hardware design, antenna, power management, filtering, passive devices and certification standards. The RSL 10 product series launched by Ansemy Semiconductor has ultra-low power consumption Bluetooth features to help design and import more easily. According to the introduction, RSL 10 adopts the ultra-small complete scheme, including the antenna, all discrete components and crystal oscillator, and uses the compact (6mm x 8mm) BLE hardware scheme, which is suitable for all applications. At present, it has become the lowest power consumption in the industry. Without RF design expertise, it can complete the integrated design import by putting in PCB. More importantly, it has passed the regional standard certification in advance, saving time and money. It is reported that RSL 10 is widely used in energy acquisition switch, temperature sensing BLE node, Bluetooth 5 Internet of Things development kit and other solutions. In addition, the Ezairo pre-suit series of hearing aid chips suitable for wireless and non-wireless audio processors of hearing aids and related introductions are also introduced.
Wearable devices help the development of health monitoring
Nowadays, people’s health is always in the process of dynamic change, which will change with our daily diet, exercise and even sleep and other factors, which makes it difficult for people to grasp their health status in time. Therefore, a wide variety of wearable devices appear on the market, which can monitor almost all human activities, such as walking, sleeping, and even monitoring blood sugar in the body, etc., which make up for the real-time health detection and report that traditional health examination can not complete, and are welcomed by more and more people as an emerging medical field. Of course, the development of wearable equipment industry can not be achieved overnight. It also needs the joint efforts of the upstream, middle and downstream industries to promote the healthy and healthy development of the industry.
