“…These sensors require expensive hardware and strict positional requirements and it is very difficult to fulfil all these requirements. In this regard, efficient and low cost flexible resistive sensors have been implemented to monitor respiration but bending strain will induce errors in the measurement of resistive sensors.…”

This paper describes a fully‐drawn pencil‐on‐paper based low‐cost capacitive sensor for non‐invasive respiration monitoring. The sensor utilizes the hygroscopic character of the paper to measure the breathing rate and pattern. The adsorption and desorption of water molecules on paper during inhalation and exhalation results in variation in its dielectric constant. This change in dielectric constant during respiration reflects the change in capacitance of the sensor. By interfacing the sensor with the microcontroller, the capacitance data was acquired and transferred to a smartphone through Bluetooth communication. Being a low cost, wearable, non‐invasive and disposable sensor, it holds tremendous potential in healthcare technology and can be commercialized into a viable product for easy‐to‐use diagnostic purpose.

“…In the last decade, engineering the dielectric layer with microstructures has shown great promises in elevating the sensitivity. As has been demonstrated in the burgeoning studies, the microstructured surface includes a broad range of surface morphologies such as pyramids, [ 38,75,216,217 ] pillars, [ 218–220 ] wrinkles, [ 213,221–223 ] and domes. [ 224 ] A representative pyramid microstructure is depicted in Figure a to elucidate how the air gap boosts the sensitivity.…”

Over the past decade, a brand‐new pressure‐ and tactile‐sensing modality, known as iontronic sensing has emerged, utilizing the supercapacitive nature of the electrical double layer (EDL) that occurs at the electrolytic–electronic interface, leading to ultrahigh device sensitivity, high noise immunity, high resolution, high spatial definition, optical transparency, and responses to both static and dynamic stimuli, in addition to thin and flexible device architectures. Together, it offers unique combination of enabling features to tackle the grand challenges in pressure‐ and tactile‐sensing applications, in particular, with recent interest and rapid progress in the development of robotic intelligence, electronic skin, wearable health as well as the internet‐of‐things, from both academic and industrial communities. A historical perspective of the iontronic sensing discovery, an overview of the fundamental working mechanism along with its device architectures, a survey of the unique material aspects and structural designs dedicated, and finally, a discussion of the newly enabled applications, technical challenges, and future outlooks are provided for this promising sensing modality with implementations. The state‐of‐the‐art developments of the iontronic sensing technology in its first decade are summarized, potentially providing a technical roadmap for the next wave of innovations and breakthroughs in this field.

“…[ 3–5 ] Assessment of the diaphragmatic movement during breathing (dash line, Figure ) can provide the early recognition of human diseases like abnormalities apnea, asthma, cardiac arrest, and lung cancer. [ 6,7 ] Furthermore, the obstructive sleep apnea syndrome (SAS), arising from the collapse of the soft tissues at upper respiratory tract, poses a huge hazard in human health and safety and the potential causes for various diseases, such as diabetes, hypertension, stroke and even nocturnal death. Monitoring the respiratory behaviors and status favors the immediate alarms for SAS occurrence and appropriate treatment in time, which is of great significance to decrease the risk of respiratory diseases and possibility of sudden death.…”

In mammals, physiological respiration involves respiratory cycles of inhaled and exhaled breaths, which has traditionally been an underutilized resource potentially encompassing a wealth of physiologically relevant information as well as clues to potential diseases. Recently, triboelectric nanogenerators (TENGs) have been widely adopted for self‐powered respiration monitoring owing to their compelling features, such as decent biocompatibility, wearing comfort, low‐cost, and high sensitivity to respiration activities in the aspect of low frequency and slight amplitude body motions. Physiological respiration behaviors and exhaled chemical regents can be precisely and continuously monitored by TENG‐based respiration sensors for personalized health care. This article presents an overview of TENG enabled self‐powered respiration monitoring, with a focus on the working principle, sensing materials, functional structures, and related applications in both physical respiration motion detection and chemical breath analysis. Concepts and approaches for acquisition of physical information associated with respiratory rate and depth are covered in the first part. Then the sensing mechanism, theoretical modeling, and applications related to detection of chemicals released from breathing gases are systemically summarized. Finally, the opportunities and challenges of triboelectric effect enabled self‐powered respiration monitoring are comprehensively discussed and criticized.
