“Elderly Dependable” Smart Cane
Captain: Li Hang
Team Members: Ying Chengxu, Jin Pei, Huang Yanyi
Due to the aging population, the quality of life for the elderly has become a growing concern. The social issue of “not daring to help the elderly when they fall” has emerged. With the development of the economy and the popularity of smart products, we have designed the “Elderly Dependable” Smart Cane, which is affordable for the working class. The target audience for the product includes the elderly, the visually impaired, the disabled, and those with intellectual disabilities.
The product features fall alerts (sending SMS to the caregiver’s phone when a fall occurs and issuing a vocal distress call), emergency calls (one-click dialing when the elderly feel unwell), real-time GPS positioning, and environmental awareness. It also serves as a support aid with a non-slip base. The height of the cane can be adjusted to meet different height requirements, fulfilling users’ needs for exercise, safety, and entertainment. Compared to domestic products, we achieve self-generating power, converting mechanical energy into electrical energy, which is energy-efficient and environmentally friendly, reducing the burden of charging for the elderly. Additionally, caregivers can bind the smart cane to an app on their phone, allowing for information exchange over the internet to monitor the elderly’s status, including real-time GPS positioning, checking environmental temperature, and setting medication reminders, further reflecting humanistic care.

Team Members: Li Qingjuan, Zhang Yiying, Cai Junxian
With the widespread adoption of smartphones, integrating various aspects of daily life with mobile phones has become a trend. However, in the innovative development of mobile phones, phone cases are often overlooked. This project provides a phone case design that can weigh items at any time and measure temperature and humidity, accurately obtaining data, and integrates with a counterfeit detection light, embedding the phone case’s application into daily life through Bluetooth modules to display relevant data in the phone software.
While achieving related functions, we also strive for lightweight and aesthetic design of the phone case. The main functions are realized through an improved soft, moderately thick phone case, embedding a Mega2560 microcontroller, temperature and humidity sensors, Bluetooth, electronic weighing products, and a counterfeit detection light, with a hidden weighing hook embedded within; utilizing Bluetooth modules to obtain relevant data, processing the obtained data through software coding for user convenience.
This project primarily tests the weighing effect and precision of temperature and humidity, electronic weighing products, and the display of codes, reflecting the concept of the Internet of Things. By combining the functions of the phone and the phone case, we provide an idea for expanding the functionality of phone cases. Furthermore, the design of the phone case focuses on the embedded core, making it convenient and versatile.

Smart Anti-Loss Tracker
Captain: Li Niwei
Team Members: Chang Yue, Dou Ruqiang, Peng Qingsong
In campus life, there is a common phenomenon where people often post on social media looking for their meal cards; the more anxious one is, the harder it is to find their wallet. When going out to play, one might unknowingly lose their wallet.
Our team started from small issues in daily life and observed that people almost never part with their phones. If we could link the phone to small items like meal cards and wallets, then when a meal card or wallet is lost, an alert could be sent through the phone, allowing people to receive timely information and avoid losses. Therefore, our team integrated the sensitivity of Bluetooth sensors, developed a mobile app through self-programming, and aimed to achieve timely alerts for lost items.
The design flowchart is as follows:
The market application of this product is also very broad. Almost all office workers are our potential customers. Additionally, the product can be further promoted to governments, enterprises, and residential properties to activate timely anti-theft systems for fixed assets. If fixed assets are moved beyond the set range, an all-range alarm will automatically trigger, promptly notifying security and the police to avoid significant property losses. Technically, this product has considerable room for improvement, such as further accurately measuring signal strength to enhance positioning accuracy and potentially integrating artificial intelligence systems to make the software more user-friendly. There is also vast technical improvement space for home anti-theft applications. In summary, this is just the starting point for this product, with very promising prospects.
Smart Travel Case
Captain: Ma Ruixiong
Team Members: Lin Zhenye, Wan Qingwen, Tong Lei
We designed a smart travel case that automatically follows the user as they walk. Three Bluetooth 4.0 modules are installed on the case as beacon nodes, connecting with a central microcontroller system, while the user’s phone Bluetooth signal acts as an unknown node. The app installed on the user’s phone contains a dynamic Bluetooth triangulation algorithm, which continuously detects the RSSI feedback values from the three Bluetooth modules and performs dynamic differential processing to derive the most accurate movement direction of the unknown node at the next moment, feeding this back to the microcontroller system to control the travel case’s movement.
Additionally, utilizing the chip’s serial communication function, we connect it with the GSM module SIM900 to establish data connection. By programming the chip to send AT commands to the GSM module, it can send alarm SMS or make calls to achieve the goal of alerting.

Team Members: Fu Mingxuan, Fan Zexin
Our team designed a self-service vision testing device that allows a single person to complete the entire vision testing process.
The method is based on the programmable logic device basys3, simulating manual random instructions through verilog HDL programming. It randomly displays the direction of the letter E on the monitor, and the test subject operates the four-direction keyboard to input the direction of the E they see. The program system compares the actual direction with the input direction, and based on the accuracy, proceeds to the next test, ultimately calculating the visual acuity value and displaying the result numerically. We will also include a voice peripheral module for basic operation prompts and assist in hearing tests. This product is a fully automatic vision and hearing monitoring device based on Basys3, where FPGA (Field-Programmable Gate Array) is a type of semi-custom circuit that emerged in the field of Application-Specific Integrated Circuits (ASIC), solving the shortcomings of custom circuits and overcoming the limitations of the number of gate circuits in original programmable devices. It utilizes the basys3 main control chip and rich peripheral modules to achieve vision measurement functionality.
