Several studies have shown that mouthguards can reduce orofacial injuries among athletes. Comfort and wearability factors were compared among 40 high-school athletes for custom-made and self-adapted mouthguards. Both offered adequate protection, but overall the participants preferred the custom-made mouthguard.

Wearable pressure sensors capable of adhering comfortably to the skin hold great promise in sound detection. However, current intelligent speech assistants based on pressure sensors can only recognize standard languages, which hampers effective communication for non-standard language people. Here, we prepare an ultralight TiCT MXene/chitosan/polyvinylidene difluoride composite aerogel with a detection range of 6.

Wearable robots are often powered by elastic actuators, which can mimic the intrinsic compliance observed in human joints, contributing to safe and seamless interaction. However, due to their increased complexity, when compared to direct drives, elastic actuators are susceptible to faults, which pose significant challenges, potentially compromising user experience and safety during interaction. In this article, we developed a fault-tolerant control strategy for torque assistance in a knee exoskeleton and investigated user experience during a walking task while emulating faults.

Microfluidic chips play a crucial role in wearable sensors for sweat collection. However, previously reported wearable microfluidic chips, such as those based on poly(dimethylsiloxane) (PDMS) and paper, encounter sweat accumulation at the skin-sensor interface in practical applications, which consequently affects both sensing stability and wearing comfort. Herein, we propose a composite nanofiber membrane (CNMF)-based microfluidic chip for in situ sweat collection.

Conventional wearable flexible sensing systems typically comprise three components: a flexible substrate that contacts the skin, a signal processing module, and a signal output module. These components function relatively independently, resulting in a complex system that lacks sufficient integration. Therefore, developing an integrated wearable flexible sensing system by combining the flexible substrate, the signal processing module, and the signal output module not only enhances performance and comfort, but also reduces manufacturing costs and the risk of failure.

Parkinson's disease (PD) prevalence is projected to reach 12 million by 2040. Wearable sensors offer a promising approach for comfortable, continuous tremor monitoring to optimize treatment strategies. Here, we present a wristwatch-like triboelectric sensor (WW-TES) inspired by automatic watches for unobtrusive PD tremor assessment.
