The paper "A Highly Sensitive Force Sensor with Fast Response Based on Interlocked Arrays of Indium Tin Oxide Nanosprings toward Human Tactile Perception" is an excellent example of an article on physics. The research on the sensor capable of recognizing the tactile feeling will find useful applications in artificial systems. The sensor will find essential uses in artificial systems that need the implemented human functions for various applications like prosthetics, robotics, human-machine interfaces, wearable electronics, and healthcare monitoring. There has been much effort in the development of tactile sensing devices which uses piezoelectric, triboelectric and ferroelectric characteristics to detect sensitive dynamic and static pressures.

However, there are limitations in the extension of such approaches to tactic sensor since pressure recognition requires operating mechanism of detection of force. Notably, the majority of the previous force sensors depend on polymeric materials for functionality. Such materials have slow responses to deformation and recovery thus cannot adequately measure high-frequency vibrations. The Indium Tin Oxide Nanosprings (ITONS) force sensor has an ultrafast response and high sensitivities with excellent cycling stability and reproducibility to both dynamic and static pressures over an extensive range of frequency and pressure.

The work is innovative because of the functionality is based on the change of resistance in the interconnecting array of ITO NS with the application of vertical pressure. The fabrication method of the force sensor involves sandwiching the vertically aligned ITO NS structure between two independently prepared polyethene naphthalate substrate. The development of the force sensor requires indium tin oxide nanosprings and a polyethene naphthalate substrate. The species being sensed here is tactile perception. Characterization method involves the measurement of changes in resistance after external pressure application because of changes in the interlocking displacement.

Also, there is a measurement of deformation time and recovery time. Therefore the detection method is the change in resistance of the interlocking arrangement of ITO NS structures. Transduction method requires the measurement of sensitivity (S). The sensor is classified as a tactile perception sensor. The research concluded that the ITO NS force sensor has a higher sensitivity than the force sensors that uses polymeric materials. The researchers properly arranged various aspects of the article. The English used is appropriate thus making it possible for the readers to understand the concepts explained.

The researchers were successful in developing of force sensor that uses the Indium Tin Oxide Nanosprings which is more sensitive than previously used force sensors whose operation depend on polymeric materials. This work is a significant improvement of the force sensors used before since the force sensor developed is efficient in detecting high-frequency vibration. The ITO NS force sensor will find useful applications in artificial systems such as robotics. The researcher clearly labelled parts of the article including headings, references, conclusion, experimental section, and figures.

However, the authors did not include the tables in the article and instead request the readers to visit the Wiley Online Library find the supporting information or find out directly from them. It is important to note that omitting the tables on the article may be a disadvantage to some readers who cannot access them the Wiley Online Library. The authors clearly explain the concepts of the article and the readers can effectively understand them. The researchers did their work as per the ethical requirements.

I enjoyed the article since it explains the new force sensor which much sensitive than the force sensors based on the polymeric material. The ITO NS force sensor can detect high-frequency vibrations. Finally, I like how the authors used figures to illustrate the various concepts in the article.
