“…From the sensorial point of view, medical applications are also very similar to those in soft or flexible robotics. This type of approach to transducers has been described in [6], which presents a sensor for monitoring biomedical activities or one that can be used in robotic applications. The study presents the structure of the TIPS sensor with a sensitivity in the range of S min > 200 kPa −1 , S max > 45,000 kPa −1 , and a wide range of pressure change detection in the range of 20 Pa up to 1.4 MPa.…”

The article presents the negative aspects of the influence of static and dynamic acceleration on the accuracy of pressure measurement for a selected type of transmitter. The influence of static accelerations from catalog notes was shown and compared with the tests results for a few selected sensors. The results of research on the influence of dynamic acceleration for various types of its variability for selected converters are presented. Moreover, a method of measurement patented by the authors that uses a complex transducer is shown. The method allows for more accurate measurements on moving objects. The tests were performed based on the proposed method. The obtained results of the influence of acceleration on the classical sensor as well as the construction using the proposed method are shown. The paper presents approximate pressure measurement errors resulting from the influence of acceleration. For example, errors in measuring the speed of an airplane may occur without the proposed method. The last part of the article presents a unique design dedicated to a multi-point pressure measurement system, which uses the presented method of eliminating the influence of accelerations on the pressure measurement.

“…Flexible sensors, as a key element of wearable devices [4][5][6], have become one of the research hotspots due to their various promising applications [7,8], such as in human−machine interfaces, electronic skin, timely health monitoring, and soft robotics [9]. Based on the signal transition mechanisms, flexible sensors can be classified into capacitive [10,11], piezoelectric [12], resistive [13,14], and triboelectric types [15,16]. Among these, the capacitive sensors had been widely applied based on the advantages of outstanding temperature insensitivity, low power consumption, rapid dynamic response, and simple architecture design [17].…”

The flexible and wearable capacitive sensors have captured tremendous interest due to their enormous potential for healthcare monitoring, soft robotics, and human−computer interface. However, despite recent progress, there are still pressing challenges to develop a fully integrated textile sensor array with good comfort, high sensitivity, multisensing capabilities, and ultra-light detection. Here, we demonstrate a pressure and non-contact bimodal fabric-only capacitive sensor with highly sensitive and ultralight detection. The graphene nanoplatelets-decorated multidimensional honeycomb fabric and nickel-plated woven fabric serve as the dielectric layer and electrode, respectively. Our textile-only capacitive bimodal sensor exhibits an excellent pressure-sensing sensitivity of 0.38 kPa−1, an ultralow detection limit (1.23 Pa), and cycling stability. Moreover, the sensor exhibits superior non-contact detection performance with a detection distance of 15 cm and a maximum relative capacitance change of 10%. The sensor can successfully detect human motion, such as finger bending, saliva swallowing, etc. Furthermore, a 4 × 4 (16 units) textile-only capacitive bimodal sensor array was prepared and has excellent spatial resolution and response performance, showing great potential for the wearable applications.
