“…The predefined locomotion modes were identified as follows: (1) level walking (LW), (2) ramp ascent (RA), (3) ramp descent (RD), (4) stairs ascent (SA), (5) stairs descent (SD). The above locomotion modes are consistent with those in other relevant works [16][17][18][19]. Ten healthy subjects (6 male and 4 female) were asked to walk using the five locomotion modes and ultimately produced 3,573,241 observations, with 2707 strides in total.…”

“…Ten healthy subjects (6 male and 4 female) were asked to walk using the five locomotion modes and ultimately produced 3,573,241 observations, with 2707 strides in total. The ramp was angled at 10 degrees, and the stair height was 10 cm [17].…”

“…A locomotion mode recognition system generally consists of two parts: a data acquisition front-end and a recognition algorithm back-end. For the former, wearable sensors, including kinematic sensors (IMUs) [14][15][16], kinetic sensors (interaction force or ground reaction force sensors) [17], and electromyography (EMG) sensors [16][17][18][19] are widely used. For the latter, machine learning is frequently used for analysis of the physical information received from the front-end.…”

“…In [16], seven EMG and two accelerometer sensors were used, and five locomotion modes were classified by SVM and LDA, with an accuracy of 95.2%. In [17], EMG, GRF, interaction force and position sensors were integrated to classify five locomotion modes with Bayesian LDA and reached an accuracy of 96.1%.…”

“…To address this, in this article, we present a smart locomotion mode recognition system with a high experimentally demonstrated classification accuracy of 96.38% by utilizing only two EMG and two GRF flexible sensors and a machine learning algorithm. Compared to the previous studies [14][15][16][17][18][19], the developed technique benefits from simplicity by smartly designing measurement locations and selecting highly correlated features for the machine learning algorithm while maintaining a high detection accuracy.…”

In order to quantify the manipulation process of acupuncture, in this article, a piezoelectric glove based wearable stress sensing system is presented. Served as the sensitive element with small volume and high tensile resistance, PVDF greatly meet the need of quantitative analysis. Through piezoelectric force sensing glove, the system is capable of detecting both perpendicular stress as well as shear stress. Besides, key parameters including peak stress at needle are detected and extracted, potentially allowing for a higher learning efficiency hence advancing the development of acupuncture.

Applying sensors in biomedical institutions and home‐based stroke rehabilitation is now a global research focus. In this review paper, the relationship between stroke diseases’ physiology mechanism and diverse sensors’ functionalities is detailed explained. The review starts by interpreting how stroke influences motion abilities and then introduces broadly adopted physical training methods. After, the working principles of sensors and their use to objectively provide patients’ body information for stroke rehabilitation status are discussed. The content of the paper aims to not only review the state‐of‐the‐art works of developing sensors for assisting in evaluating stroke patients’ status but also bridging the gap between medical staff and engineers.

Accurately identifying user needs in terms of assist timing and magnitude presents challenges for wearable power‐assist limb devices. Traditional approaches to gait perception—such as estimating joint angles and walking conditions—often rely on electronic sensors and neural networks, which can compromise wearability and impose high computational demands. Physical reservoir computing (PRC), which utilizes the inherent nonlinearity of physical systems for data processing, offers a promising alternative. This study proposes a novel self‐estimated physical reservoir computing (SEPRC) model that improves traditional PRC models for gait perception using a wearable pneumatic physical reservoir. A core feature of the new model is the self‐estimation structure, wherein the outputs of the physical reservoir are mutually estimated. Experimental evaluations indicate that the SEPRC model outperforms traditional PRC in clustering time‐series reservoir output sequences with the same dimensionality. This enhanced clustering performance is subsequently leveraged in gait perception by incorporating Takagi–Sugeno fuzzy logic for joint angle estimation and a softmax activation function for walking condition recognition. The newly proposed time‐sequence processing approach facilitates the traditional PRC model to achieve higher accuracy in gait perception and greater robustness against the user's walking pattern variations while preserving PRC's hardware simplicity.
