Flexible capacitive pressure sensors for wearable electronics

Abstract

Flexible pressure sensors have attracted more and more attention recently due to their broad applications, such as electronic skin and wearable electronics for health monitoring. Among them, capacitive flexible pressure...

System-wide analyses reveal essential roles of N-terminal protein modification in bacterial membrane integrity

“…Intriguingly, emerging data suggest that an intricate balance of formylation and deformylation is crucial for membrane-associated cellular functions. A previous study (Ranjan et al, 2017) and our recent work (Yang et al, 2022) demonstrated that a significant fraction of the membrane and secretory proteome is resistant to deformylation under physiological conditions, suggesting that fMet retention on some membrane and secretory proteins may be necessary. Our current work showed that the deformylation of a distinct set of the proteome is crucial for maintaining the proper structure and function of the bacterial membrane.…”

Recent Advances in Flexible Sensors and Their Applications

“…Generally, conventional biomedical equipment is rigid and cannot be fitted closely at the monitoring site, therefore resulting in inaccurate monitoring data and making the patient uncomfortable while wearing a device. Flexible sensors are easily fitted onto human skin due to their great flexibility and stretchability [2,[110][111][112][113]. These sensors possess…”

“…Generally, conventional biomedical equipment is rigid and cannot be fitted closely at the monitoring site, therefore resulting in inaccurate monitoring data and making the patient uncomfortable while wearing a device. Flexible sensors are easily fitted onto human skin due to their great flexibility and stretchability [2,[110][111][112][113]. These sensors possess high sensitivity, stretchability, and quick response time, due to which they would be a sustainable and ideal choice for future applications in the biomedical field such as pressure detection, sound variation, vital sign monitoring, and pulse monitoring (Figure 5).…”

Transparent stretchable hydrogel sensors: materials, design and applications

“…57 The pressure sensor rearranges the electrostatic potential of internal ions, causing changes in electrical resistance, which is based on the piezoresistive effect of the hydrogel. 58 The temperature sensor utilizes the monotonic increase of the electrical conductivity of the hydrogel with temperature to monitor the temperature change in real-time. 54 For the humidity hydrogel sensor, the hydrophilic groups on hydrogels/organohydrogels can absorb and desorb moisture from the surrounding environment upon relative humidity variations, which can change the electrical properties.…”
