A highly versatile, low-cost, and robust tactile sensor capable of acquiring load measurements under static and dynamic modes employing a poly(vinylidene fluoride-co-trifluoroethylene) [P(VDF-TrFE)] micronanofiber element is presented. The sensor is comprised of three essential layers, a fibrous core P(VDF-TrFE) layer and two Ni/Cu conductive fabric electrode layers, with a total thickness of less than 300 μm. Using an in situ electrospinning process, the core fibers are deposited directly to a soft poly(dimethylsiloxane) (PDMS) fingertip. The core layer conforms to the surface and requires no additional processing, exhibiting the capability of the in situ electrospinning fabrication method to alleviate poor surface contacts and resolve issues associated with adhesion. The fabricated tactile sensor displayed a reliable and consistent measurement performance of static and instantaneous dynamic loads over a total of 30 000 test cycles. The capabilities and implications of the presented tactile sensor design for multimodal sensing in robot tactile sensing applications is further discussed and elucidated.

“…In addition, the development of physical sensors for respiration and skin gas measurement has also received much attention in the era of real‐time and portable healthcare systems. Stretchable sensors and wearable technologies for breathing and gas‐fluid monitoring are also becoming more important [87,88]. Combining wearable sensors with biosensors for detecting signals such as temperature, humidity, airflow, stress, and strain will enable more advanced human monitoring.…”

Biosensors and chemical sensors for healthcare applications are garnering interest due to their potential to provide continuous and real-time physiological information, chemical information, and noninvasive measurements of biochemical markers in human biofluids, such as tears, saliva, sweat, interstitial fluid, and human volatiles. Recent developments have focused on electrochemical biosensors and monitoring of metabolites, proteins, chemicals, and bacteria. The measurement of biophysical quantities of the human body has been studied in healthcare and medicine. Many flexible, wearable, and detachable sensors have been developed and commercialized to monitor relevant parameters in sports, healthcare, and medicine. Here, we introduce many challenges regarding the integration of sensors and biosensors into the monitoring of biological and chemical information for the internet of things (IoT) in healthcare. IoT sensors are set to improve quality of life (QoL) and living standards.

“…We demonstrated the potential use of our system in biomedical applications such as cell treatment by simultaneously generate and deliver biocompatible PVDF particles onto collector for analysis. The same polymeric solution is used across experiments to preserve the consistency between results and comparability with our previous work [16]. Polyvinylidene fluoride (PVDF) powder (Mw~ 534,000, Sigma-Aldrich) is dissolved in a 4:1 ratio mixture of N,N-Dimethyleformamide > 99a% (DMF, Sigma-Aldrich) and Acetone ≥ 99.5% (ACE, Sigma-Aldrich).…”

This work presents a new approach to simultaneously generate and deliver polymeric aerosol for inhalational therapeutics. We developed an electrohydrodynamic nebulizer (eNeb) based on the principle of the balance of charge. Our nebulizer contains two electrodes, each serves as the emitter and also the reference electrode of each other. This allows the device to generate clouds of oppositely charged particles and ion wind from corona discharge. The two clouds impinge, neutralize each other, and the generated particles are pushed forward by the momentum accumulated from the corona discharge. This approach allows our eNeb to transforms a liquid solution into polymeric particles with the size within 1 -5 µm range and directly deliver them toward a target. Herein, we investigated our eNeb via simulation, experiments, and analysis of final products. This single-step nebulizer enables drug delivery via inhalational approach using nanomedicine.
