GOLD - Speak for dysarthria (National Yang-Ming University, Department of Biomedical Engineering)
This study proposed a dysarthria voice conversion (DVC 3.1) system to help dysarthric patients have the ability to talk clearly and freely with people, which the voice conversion (VC) technology was used in this study. More specifically, we used a gated convolutional neural network (Gated CNN) with the phonetic posteriorgrams (PPGs) features to covert the features of dysarthric speech to target speaker speech features, firstly. Following, the WaveGlow vocoder technology was used to synthesize converted speech from this converted speech features. The results of speech intelligibility in the listening test and speech naturalness in MOS score show that our proposed system provided higher intelligibility and naturalness scores. These results suggested that the DVC 3.1 undoubtedly can be used as a communication assistive system for dysarthria patients to take advantage of in their daily live.

Near-infrared Spectroscopy in Sarcopenia during rehabilitation
The WTO predicts that by 2050, the global population of people aged 60 and over will increase from 900 million in 2015 to 2 billion. Several studies have shown that skeletal muscle produces and secretes molecules called myokines, which regulate brain function, including mood, learning, motor activity and neuronal injury protection. Furthermore, it may also lead to other brain-related diseases. Therefore, the purpose of this project is to develop a sarcopenia monitoring system that simultaneously evaluates muscle hemoglobin changes and brain oxygenated and deoxygenated hemodynamic changes using near-infrared spectroscopy to evaluate the effects of exercise programs. Sarcopenia is well documented to increase the risk of cognitive decline. Suppose we can quickly intervene and monitor brain changes in the early stage of sarcopenia, the therapist can change the exercise program in a rolling wave planning to increase the treatment effect and prevent brain lesions. For the device, we greatly reduce the size of the device, increase the signal quality, and achieve module expansion through circuit design. Finally, as a home rehabilitation device for patients with sarcopenia, this device can effectively rehabilitate and prevent brain lesions, so that the lives of the elderly and patients with sarcopenia can be more effectively improved.

Using deep learning-based pose estimation technology to develop a novel rehabilitation evaluation system
Target group: 1) Individuals with stroke experiencing arm and hand impairments. 2) Rehabilitation therapists.
Development Objective: To develop a reliable and objective AI and computer vision-based automated arm and hand rehabilitation assessment system for people with stroke.
Needs analysis: Currently, individuals with stroke are required to be evaluated by rehabilitation therapists during in-person sessions in the hospital. It is less accessible during the pandemic when person-to-person contacts are limited and for people living in remote areas. An accurate rehabilitation assessment system that can be done remotely is needed to address the above issues.
Prototype design and application: We developed an automated version of the ArmCAM test, an arm and hand assessment tool based on the AI skeleton posture detection and object detection technologies. We designed a toolbox that includes all the required assessment tools along with the instructions. To obtain the assessment results, patients only need to record their movements with any camera on their phone or computer following the instructions provided in the toolbox. By utilizing the system, users (e.g., therapists, people with stroke) can easily track changes after rehabilitation interventions without visiting the hospital.
Safety precautions: No safety precautions are required as the assessment system is non-invasive.

< FootHow >for diabetes foot care
The global diabetes population is increasing at a rate of 10 million per year. About 25% of diabetic patients will have diabetic foot, while 60% of the diabetic foot may have foot ulcers due to poor foot care or wound, and nearly 20% may lead to amputation. The most important thing to prevent diabetic foot is frequent screening and regular monitoring. At present, clinicians use manual methods to perform clinical examinations, including foot appearance, temperature, and sensory nerve neuropathy. The entire process takes about an hour and is quite time-consuming and labor-intensive, which leads to the current average diabetic patient being checked about every six months to a year. FootHow aims to solve the pain points of clinical diabetic foot ulcer and foot amputation, applying three core technologies (1) AI appearance inspection (2) infrared thermometer, and (3) intelligent sensory neuropathy assessment, which is original and novel and the leading technology in preventing diabetic foot ulcers in the world. The core value of FootHow is "Prevention, Precision, and Personalization" and the ultimate goal is to keep diabetic patients away from lower limb amputation.

Wearable Exoskeleton for Knuckle Muscle Rehabilitation
Stroke cases with hand spasm usually incapable of doing hand flexion and extension. In other words, stroke have an effect on hand function, which will fail to participate in activities of daily living. The research has shown that consecutive long-lasting and stretch-shortening cycle brings many benefit to stroke patients to rehabilitate their hand function, especially reducing stretch reflex sensitivity and muscle stiffness. In addition, repetitive movement can reduce muscle tension and stimulate the brain to learn the specific action.
We designed an exoskeleton to control hand movement. Patients can control the exoskeleton by themselves through the remote control which makes the device easier to use. The study and development stage have also shown that the three-finger function is the most important movement. Thus, we designed three-finger shape to train clients hand function.
Low cost and safety switch are two extraordinary advantages. The price between the existing electronic hand and our device produced by 3D printing technology vary greatly. Besides, the device equipped with a safety switch can reduce the usage of electricity.This exoskeleton device could use as a home-based rehabilitation way for stroke cases to train their hand function and thus achieve their independent living lifestyles.

Customized Hand Exoskeleton Rehabilitation Device Many stroke patients suffer from upper extremity hemiplegia, and patients who have been injured for a long time after sports injuries can also cause muscle degeneration or atrophy and cannot coordinate movements. They need to go to the hospital for long-term physical therapy and rehabilitation by manpower or expensive but standardized machines. There are some problem that rehabilitation machines are expensive and cannot be applied to all rehabilitation patients on the market today. Therefore, this project designs a low-cost and customizable 3D printed hand exoskeleton. During rehabilitation, added the concept of "Mirror Therapy" that stimulates the brain with vision. In this research, a bending sensor is used to measure the bending angle of a normal finger, which is transmitted to the Arduino Nano microprocessor to convert into pulse width modulation (PWM), and then output to a motor to pull the 3D printed exoskeleton with nylon thread to drive the hand in need of rehabilitation.

Peripheral - The future of Walking Navigation and Tangible Interface
According to many papers and journals and the perspective of blind and low vision (BLV) community, assistive technologies should go beyond the being functionally equivalent to visual perception, they should also work in a way for the users to be able to integrate into society naturally without expressing implicit needs; furthermore, users want to be able to live autonomously without having to reveal one's blind identity, and avoid the existing stereotypes of society.
After the team members have been exposed to individuals with disabilities and grasped the idea of accessibility, they wish to employ UI/UX and other natural interaction modes to design. Therefore, PERIPHERAL was created, we employed the smart obstacle detector to connect with the GPS of the mobile phone, set up vibration feedback, tried to use the more sensitive nerve parts of the fingertips, and combined the wearable gloves with functions such as vibrators and bending sensors to make the operation and experience of the blind simple.
The design of the gloves is relatively light and secret, which can take into account the implicit demands of visually impaired people who don't want to intentionally divulge their disability. We have developed prototypes with the goal of creating a barrier-free interface, and we hope to become a humanized wearable instrument in the future.

Smart Posture Corrector
In a technology-advancing era, there are more populations that rely on smartphones from day to day. It is becoming a necessity for humans, which is access to the internet and available for communication. As smartphones dominated our daily life, people started to feel sour and tight on their necks. People have continued poor posture for an amount of time that is enough to cause muscle tensions, numbness, shoulder, or even neck pain in their upper extremities. Therefore, our team developed a device to assess the posture that eases the patient’s neck pains. Our invention includes 4 parts: a sensor, a control panel, a speaker, and an oscillator. The sensor is designed to be placed at the top and the back of the head. It is used to measure the general angle of our neck, which is practical and crucial for this design. Even if patients wear hats or hair accessories, the sensors will not be blocked, it is still detectable. Thus, correcting neck posture devices can decrease the incidence of muscle spasms, and neck pain, and demonstrate a concise posture when using smartphones.

Tissue Repairing Mouse Pad
Long-term use of peripheral computer equipment in an improper posture can quickly result in nerve compression and wrist tissue inflammation, which can cause symptoms like carpal tunnel syndrome. By incorporating the electrical stimulation and heat-generating function into the mouse pad and giving the impression of an ergonomic design, this gadget attempts to decrease the likelihood of inflammation of the user's wrist tissue. The wrist rest on this device has several purposes. A heated wire is located inside to raise the wrist rest's warmth and transfer it to the wrist. A region printed with electrically conductive printing ink on the wrist rest's surface allows the system to determine if the wrist is in the rest position by observing how the resistance changes when the wrist makes contact. When applying microcurrent electrical stimulation, this region also acts as the contact surface where the current is sent to the wrist. The ergonomically designed portion of the mouse's operating surface is an inclined surface with a 3.43 degree inclination angle. When using a mouse, it may provide a more comfortable wrist angle for the user.

The idea of a mask printer comes from the serious impact of the epidemic on living habits. In recent years, wearing masks has become a part of daily life. But younger children or autistic children resist and pull off masks because they don't understand the use of wearing masks and are not used to wearing masks for a long time. The mask printer can print the patterns you like on the mask, freely draw your favorite cartoon characters on the interface, select your favorite colors, and print them on the mask, so as to increase children's identity and sense of belonging and improve their willingness to wear the mask. Environmental friendly pigments are used in the dye. Special pigments are added into the pigments, which can remind children to replace their masks according to the dilution of the patterns.
