Project Name:
Research on wearable biosensors based on perovskite solar cells.


Brief introduction of the project:
With the development of science and technology, wearable devices are becoming more and more popular. As a new type of health monitoring equipment, wearable biosensors have the advantages of lightweight, easy to carry, real-time monitoring and so on. Wearable biosensors can detect vital sign parameters of the human body, such as heart rate, blood pressure, blood oxygen content, etc., and transmit the data to doctors or health care experts in real time to achieve continuous monitoring of personal health status.
However, as a wearable device, the large-scale application of wearable biosensors also faces the limitation of battery capacity and battery life. The use of solar cells to power it can overcome this difficulty and extend its use time. Perovskite solar cells have the advantages of high conversion efficiency, flexible deformation, etc., which is very suitable for wearable device applications.
This topic intends to use perovskite solar cells to power wearable biosensors and explore the practicability of the wearable biosensors by learning the working principle of perovskite solar cells, the design and production of sensors, and the test of power supply performance. The content of this project conforms to the scientific research ability of the undergraduate stage, which is not only innovative, but also easy to complete. It can foster students' interest in scientific research and gain a deeper understanding of wearable technology and renewable energy technologies.


Project content:
1. Study on the working principle of perovskite solar cells
2. Structural design of wearable biosensors
3. Sensor signal acquisition and processing

Topic innovation:
1. Perovskite solar cells are used as power supply system
Compared with ordinary silicon-based solar cells, perovskite solar cells have higher conversion efficiency and can be made into flexible structures, which are more suitable for wearable device applications. The use of this new solar cell to power wearable biosensors can overcome the limitations of its battery capacity and battery life, and achieve all-weather continuous monitoring, which is an innovation point of the subject.
2. Integrated design of wearable biosensors
According to the ergonomic requirements, a new wearable biosensor is designed and manufactured, which can realize the continuous monitoring of health parameters. Compared to existing commercial wearable devices, the design is more suitable for use, which is another innovation point of the project.
Through the realization of these two innovative points, the application range of wearable biosensors can be further expanded, providing more timely and convenient health status monitoring for individuals, and promoting the development of wearable technology. The subject is full of originality and application value.


Research objectives:
1. Master the working principle of perovskite solar cells
Perovskite solar cells are a new kind of thin film solar cells. Compared with traditional silicon-based solar cells, they have the advantages of high conversion efficiency and flexible deformation. Through the study of this topic, students can master the structure and working principle of perovskite solar cells andls, and lay the foundation for the subsequent design of sensor power supply system.
2. Learn the design method of sensor
The design of wearable biosensors needs to consider factors such as wearable comfort, real-time monitoring and information transmission. Through the design and production of this subject, students can be trained to comprehensively apply the knowledge, learn and master the design method of sensors.
3. Verify the practicality of the wearable biosensor
After the design is completed, it is necessary to test and verify the sensor's induction performance and the working effect of the power supply system to explore the feasibility and practicability of the design scheme. This can cultivate students' spirit of scientific inquiry and consciousness of innovation.
By clarifying the purpose of research, students can pay more attention to the learning of basic knowledge, the cultivation of design and training ability, and the verification of research results in the process of carrying out the project, which is very helpful to improve students' scientific research and innovation ability.
