The rapid development of mobile applications has greatly improved the efficiency of human access to information and knowledge. To improve the user experience of our hardware, we hope to develop an App. We have built an APP demonstration here. Firstly, the App can wirelessly connect and control the camera, receive the data sent back by the camera, process the received data, and feed it back to the user. So, the patient can know the stage of the wound recovery. Secondly, the App can record the patient's medical records, which is convenient for patients and doctors to check online, and provide individualized scientific tweets related to burn recovery. Finally, patients can communicate with doctors and other patients on this App. In the future, we will develop more functions to make our hardware devices more intelligent and convenient.

The user can adjust the working state of the camera by operating the App. The App can connect to the hardware. Patients and doctors can observe the state of engineered cells and wound healing through viewing the image data transmitted by the camera on the App.

When the wound recovers, the blue and red light control systems can be activated by turning on the blue and red LED lights, so as to degrade the Bacterial Cellulose(BC) membrane and then promote the apoptosis of the engineered fibroblast ATCC CRL-2522(BJ).

Patients need to fully understand their own diseases to avoid unnecessary panic. Based on this idea, we try to provide personalized knowledge push content with patients through App. According to the burn type and treatment progress of the patient, the knowledge and medical technology related to skin treatment and regeneration are regularly pushed to the patient. Through our App, patients can fully understand their own diseases and master more medical knowledge and information. The patient's medical record can be recorded in the App to check at any time.

Every patient needs meticulous care. In the App, we provide users with contact interfaces with doctors, pharmaceutical companies, product developers, and other authoritative figures. Users can have real-time conversations with authoritative figures, consult questions, and obtain reference opinions and help on the App.

Every patient will not become an isolated island after using our App, because we have designed a channel for patients to communicate with each other. It enables patients everywhere to communicate with through the Internet, share their experiences in treatment, and encourage each other to overcome the disease together.
