This article presents a method for detecting rotational speed by LC (inductor-capacitor) wireless sensors. The sensing system consists of two identical LC resonant tanks. One is mounted on the rotating part and the other, as a readout circuit, is placed right above the rotating part. When the inductor on the rotating part is coaxially aligned with the readout inductor during rotation, the mutual coupling between them reaches the maximum, resulting in a peak amplitude induced at the readout LC tank. The period of the readout signal corresponds to the rotation speed. ADS (Advanced Design System) software was used to simulate and optimize the sensing system. A synchronous detection circuit was designed. The rotational speed of an electric was measured to validate this method experimentally, and the results indicated that the maximum error of the rotation speed from 16 rps to 41 rps was 0.279 rps.

As the need for assistive robots increases in aging societies, various assistive robot systems including humanoid robots have been developed. Humanoid robotic hands are one of the most useful parts to assist humans efficiently. While sensing pressure or temperature from the robotic hands is extensively studied, sensing chemicals is less widely studied despite the significant importance. Here, a unique platform of smartly moving humanoid fingers actuated by chemical sensing is reported. The sensor is printed with disposable and biocompatible cellulose conductive ink materials. Rf intensity change of the sensor with NH4+ membrane depends on NH4+ ion concentration where R² is 0.9576. The smart bending motion of a finger is accomplished by logically programed actuation through detecting the change of interested ion concentration from 0.01 to 1 m at the ion‐selective membrane electrode (ISME) sensor with resulted bending angles from 10° to 67° accordingly. The overall signal‐to‐noise ratio is over 10. This sensing robot concept may be expanded to applications of microrobots which receive external stimulus, judge, and execute the actuation to carry out programed tasks.

A pressure monitoring structure is a very useful element for a wearable device for health monitoring and sports biomechanics. While pressure sensors have been studied extensively, battery-free functions working in wireless detection have not been studied much. Here, we report a 3D-structured origami-based architecture sensor for wireless pressure monitoring. We developed an architectured platform for wireless pressure sensing through inductor-capacitor (LC) sensors and a monopole antenna. A personalized smart insole with Miura-ori origami designs has been 3D printed together with conductive 3D printed sensors seamlessly. Wireless monitoring of resonant frequency and intensity changes of LC sensors have been demonstrated to monitor foot pressure for different postures. The sensitivity of the wireless pressure sensor is tunable from 15.7 to 2.1 MHz/kPa in the pressure ranges from 0 to 9 kPa and from 10 to 40 kPa, respectively. The proposed wireless pressure-sensing platform can be utilized for various applications such as orthotics, prosthetics, and sports gear.
