Presentation Title: Analysis of Resistance Signals for Flexible Sensors and Wiring Terminals

Reflection

I am grateful to Professor Chuang Wan-Chun for allowing me to participate in the 7th Annual National Academic Conference of the International Society of Mechatronic Engineering (ISME). This is the third time I have participated in an oral presentation type seminar, and after the previous two experiences, I am less nervous when presenting. I am very happy to have received the Best Paper Award this time. Because my experiment is related to sensors, I listened to different scholars' reports on different types of sensors, which gave me a lot of ideas. Through this seminar, I learned about the deficiencies in my presentation slides and how to describe them so that everyone can understand. 

Listening Session 1

Real-time Measurement of High-pressure Proton Exchange Membrane Water Electrolyzer with High-voltage-tolerant 

Flexible Six-in-one Microsensor Embedded

This article mainly focuses on the development of a high-pressure, flexible six-in-one microsensor using microelectromechanical systems (MEMS) technology. The microsensor can detect pressure, temperature, humidity, flow rate, voltage, and current. It is embedded at different positions inside high-pressure proton exchange membrane water electrolyzers (PEMWE) to monitor local changes in real-time, with the aim of improving the performance and safety of high-pressure PEMWEs.

Listening Session 2

Flexible Capacitive Tactile Sensor Made on a Flexible Printed Circuit Board for Detecting Tomato Firmness

The presenter is a student from National Chung Hsing University. This study focuses on using flexible circuit boards as electrodes and 3D printing mold to develop a flexible capacitive tactile sensor with an Ecoflex dielectric layer. The sensor is capable of measuring the hardness of tomatoes without the need to control displacement.

Listening Session 3

Piezoelectric Transducer Plate Acoustic Wave Microfluidic Mixer

The presenter is a student from National Yunlin University of Science and Technology. The research focuses on utilizing a fork-shaped electrode in surface acoustic wave devices to excite plate waves at higher frequencies than surface waves. This approach can generate stronger acoustic streaming and mixing effects to enhance microfluidic mixing.

Reflection

I would like to thank Professor Chuang for allowing me to participate in the 7th Annual National Academic Conference of the International Society of Mechatronic Engineering (ISME). It was a great opportunity for me to practice presenting my research topic, and I am honored to have received the Best Paper Award. I appreciate the ISME for organizing the conference during these challenging times and providing a platform for me to participate, observe, and learn from other students' presentations.

Listening Session 1

Flexible Capacitive Tactile Sensor Made on a Flexible Printed Circuit Board for Detecting Tomato Firmness

This study investigates the use of flexible circuit boards as electrode layers and Ecoflex as dielectric layers in a flexible capacitive tactile sensor for measuring the hardness of tomatoes. The collected hardness data is used to determine the maturity of the tomatoes in the report. 

Listening Session 2

Measurement of Membrane Electrode Assemblies in Proton Exchange Membrane Water Electrolyzers

The presenter of this report is a fellow student from the same session as us at Yuan Ze University. This student has developed a sensor that can perform three types of sensing: voltage, current, and temperature. The substrate of this sensor is made of PI, which can be used in environments that require bending, and the sensor has a smaller size compared to other sensors on the market.

Listening Session 3

Research on Posture Recognition for Intuitive Gesture Control of Unmanned Aerial Vehicles

The presenter is a student from National Changhua University of Education. This study uses the hand tracking model in mediapipe to track the hand movements and establish a neural network architecture based on the X, Y, and Z coordinates of the hand joints. The trained hand gestures are used to control the movements of an unmanned aerial vehicle (UAV). Currently, we also use mediapipe for image recognition, but with the pose detection module to determine body postures. This research can be referenced for future development of angle detection in sports training using similar settings.

Presentation Title: Analysis of Warpage in Molded Compounds for Flip Chip Packaging Processes, Stress Analysis of Different Molded Compounds in the Potting Process of Flip Chip Packaging, Strain Analysis of Different Molded Compounds in the Overmolded Packaging Process

Reflection

Thank you, Professor Chuang, for giving me the opportunity to attend this academic seminar. This was my first time participating in a presentation-style conference, and although my report was not perfect, this experience allowed me to gain insights on the fluency of my presentation and the logic of my production. It also made me realize the importance of the title and the placement of the content, as the audience may not necessarily have knowledge in this area. Therefore, the presentation should be easy to understand, and the logic of the report should be smooth to follow.

Listening Session 1

Flexible Capacitive Tactile Sensor Made on a Flexible Printed Circuit Board for Detecting Tomato Firmness

The presenter proposed and developed a flexible capacitive tactile sensor based on a flexible printed circuit board. The sensor adopts a dual-capacitor design, which can detect the hardness of tomatoes without the need to control displacement and without causing damage to the tomatoes, and evaluate their ripeness.

Listening Session 2

Measurement of Membrane Electrode Assemblies in Proton Exchange Membrane Water Electrolyzers

This article mainly explores the development of a small-volume integrated and flexible microsensor using micro-electromechanical systems (MEMS) technology, embedded in a Proton Exchange Membrane Water Electrolyzer (PEMWE) to sense the voltage, current, and temperature changes in specific areas. The microsensor operates successfully without affecting the operation of PEMWE.

Listening Session 3

Comparison of Single and Double Layer Conductive Tapes for Application in Flexible Sensor Adhesion

The presenter mainly explored the impact of single-layer and double-layer conductive adhesive tapes on the resistance value of sensors. An artificial skin coated with a metal layer by sputtering was used as the sensor to measure the resistance changes. At the same time, different ways of fixing and bonding were analyzed for their impact on the resistance value.
