“…To know the performance of the simply fabricated EM‐TENG, a brief comparison was made with TENGs from similar work by others ( Table 1 ). [ 52–55 ] Although the triboelectric layer materials in these two works were obtained in different ways, the TENGs have close electrical output performance. Figure S6, Supporting Information, shows the stability test of the sensor working continuously for 2800 s. The outputting voltage of EM‐TENG can be stabilized at 9.5 V during 2800 s operation, which can meet the daily training application.…”

“…[49] EM-TENG not only shows excellent electrical performance of an outputting voltage up to 330 V but can also be used as a smart sensor to monitor body movement. [50][51][52][53][54] In this study, the EM-TENG was attached to the elbow, wrist, and knee joints, which allowed to monitor the magnitude of change during different articular motions. Once the device senses that the neck posture is incorrect, the upper system will send an alarm signal to remind the user to correct their posture.…”

Chronic diseases have now become a societal issue globally; early detection and monitoring of these diseases are essential. Herein, a wireless intelligent health monitoring system has been developed, which includes a flexible, biodegradable eggshell membrane‐based triboelectric nanogenerator (EM‐TENG), a Bluetooth transmitting sensing terminal wirelessly, and an intelligent terminal processing digital signal reception from a host computer. This study uses natural fiber‐rich and biodegradable EMs to fabricate high‐performance friction nanogenerators. The EM‐TENG can be attachable to the neck, elbow, wrist, and waist, and convert mechanical contact into electrical output signals. By analyzing these signals, EM‐TENG can monitor and distinguish body postures, offer warnings about abnormal cervical flexion and extension, and assess the quality shot put throw motions accurately and continuously. These functions provide personal health monitoring and athletic program training monitoring for alerting and displaying through terminal devices. The devices are crucial for monitoring and rectifying motion patterns in younger individuals and certain patient groups. EM‐TENG is a wearable motion monitoring sensor, which provides a new strategy to human health, motion monitoring, and smart sports training.

“…[21,22] The flexible matrix and the conductive material are usually the most fundamental components of flexible piezoresistive pressure sensors, and the former performs a critical function in improving the sensitivity, ductility, and repeatability performance of the sensors. Researchers typically adopted polymeric materials such as polyimide (PI), [23] polydimethylsiloxane (PDMS), [24,25] and polyurethane (PU) [26] as flexible matrix for flexible pressure sensors, and the conductive materials combined with them to form the sensitive layer with force-sensitive functions are generally poly (3,4-ethylenedioxythiophene): poly(styrene sulfonate) (PEDOT: PSS), [27,22] carbon nanotubes (CNTs), [28] reduced graphene oxide (rGO), [29] and 2D transition metal-carbon nitride (MXene), [30,31] etc. When an external pressure is applied, the conductive materials in the sensitive layer are brought closer together and come into contact, leading to a drastic change in the resistivity of the sensitive layer.…”

In recent years, the prevalence of cervical spondylosis has been increasing, which is associated with unhealthy posture in daily life, flexible pressure sensors are beneficial in preventing cervical spine disorders. This work is dedicated to developing a flexible, high‐performance, and breathable device to monitor the health of the neck. Here, a flexible pressure sensor with a “sandwich” structure is presented, which incorporates patterned xylon fabric as the substrate and MXene as the sensitive layer. Furthermore, the application of silver nanowires (AgNWs) as the electrode material improves the piezoresistive performance. Combined with an internal elastic encapsulation method (IEEM), the sensor exhibits high sensitivity (1417.9 kPa−1 under pressure below 100 kPa) and a fast response time (30.77 ms). Compared with traditional flexible pressure sensors, the breathability of devices with an all‐fiber structure is nearly seven times higher, which better satisfies the monitoring requirements of long‐term wear. Finally, a wireless system is established by integrating a Bluetooth module and a terminal app. It enables monitoring and sensing of various physiological signals of the neck, as well as identification and alerting of long‐term poor posture such as prolonged neck flexion, showing a potential candidate for the applications of the next‐generation wearable device.
