Summary Reader Response (Draft #2)

In the article ”Where’s My Supersuit?” Zelik (2019), highlights the attributes and benefits of a spring-powered exosuit, which aims to prevent low back pain in the majority of adults. He also mentions that most adults have or will deal with lower back pain someday, and the suit will help to lessen stress on those muscles. The exosuit consists of common clothing material with an “assistive fabric elastic band”, coupled with an on-off switch that is activated when needed. He indicates that the absence of batteries and motors allows users to have the ability to move normally when the suit is turned off, while other exoskeletons are bulky, uncomfortable and interfere with movement. Zelik also mentions that the sleek design of the suit would hardly be noticeable when worn under everyday clothes. As I see it, an effective exosuit should help to ease tension on the lower back muscles, be comfortable and have the ability to be switched off.

First of all, one essential aspect of any exoskeleton is its ability to reduce fatigue on the muscles. The laboratory tests revealed that the exosuit is capable of "reducing erector spinae muscle activity by an average of 23-43% during leaning tasks, and 14-16% during lifting tasks" (Lamers et al., 2018, p. 1674). Although the suit does not completely remove the load on the lower back muscles, it still takes a considerable amount of stress off them. Therefore, the exosuit helps to lessen fatigue on the lower back muscles and prevents injury too.

Another important aspect of the exosuit is its modernized design. Exoskeletons are usually bulky and uncomfortable, which means that users are unable to wear them for long durations. Thanks to the absence of batteries and motors, the improved exosuit is lightweight and does not have any prominent parts. This means that the suit will be adequately low-profile and comfortable to wear under everyday clothing. Hence, with discomfort and bulkiness out of the picture, users will be able to equip the suit comfortably for longer periods.

Furthermore, the exosuit by Zelik incorporates a switch that allows users to turn the suit on or off with a 'double tap' gesture on the straps. When turned off, the suit disengages its support and the user will be able to move freely and as per normal. This aspect of the suit is particularly useful when users are switching between tasks or taking breaks. Thus, the ability for the suit to be turned on and off allow users to adapt to different circumstances.

In my opinion, one setback the exosuit possesses is that users need to have proper form when using it, as not everyone is informed on the importance of good posture when lifting and leaning. If users do not practice good form when carrying out strenuous tasks, then they are putting themselves at higher risk for injuries. Employing efficient body mechanics is crucial to prevent injuries in the long run. In my view, this problem can be solved by providing users with training that teaches them proper form when carrying out various tasks.

To conclude, these aspects of the exosuit will help to reduce stress on the lower back and prevent injuries, while being comfortable at the same time. However, users will need to be instructed on proper form before utilizing the suit for better effectiveness and efficiency.

Formal Letter

Dear Professor Brad and classmates, I am Zheng Xinyi and am writing this letter to introduce myself to you. I graduated from  Nanyang Polytechnic in the  aerospace systems and management course . My past internship in a research and development department contributed mostly to my decision to pursue mechanical engineering. I remember how fascinating it was to see my colleague working on a robot arm, which moved so rigidly yet so elegantly. This definitely sparked my interest and curiosity in the mechatronics field. Besides,  mechanical engineering is a course that is versatile and also offers mechatronics as a  specialization in the second year of our studies . In terms of communication, one of my strengths is being a good listener. I prefer to listen first before giving my replies, at the same time offering others the opportunity to voice their opinions. While listening, I will also have sufficient time to understand and process the other person's words, tone, and emotions before g

Critical Reflection

Looking back on  the objectives I have set for myself three months ago, I definitely feel more confident and comfortable during  presentations. However, there is still room for improvement such as projecting my voice and using the space around me more effectively. The greatest contribution to my improvement was of course lots of practice and research in the topic that I am presenting. Instead of memorizing a script, I came up with key points for each section and linked them together without relying on the slides. In this way, I will not stress on delivering a perfect speech, but a smooth one instead. In terms of my critical thinking skills, this was an area that required more discipline and effort to improve on. One of the things I found particularly useful is 'The Thinking Process' in instructional unit 3. "A great deal of your time at university will be spent thinking; thinking about what people have said, what you have read, what you yourself are thinking and how your t
