A Method for Measuring the Height of Hand Movements Based on a Planar Array of Electrostatic Induction Electrodes

Abstract

This paper proposes a method based on a planar array of electrostatic induction electrodes, which uses human body electrostatics to measure the height of hand movements. The human body is electrostatically charged for a variety of reasons. In the process of a hand movement, the change of a human body’s electric field is captured through the electrostatic sensors connected to the electrode array. A measurement algorithm for the height of hand movements is used to measure the height of hand movements after the direction of it has been obtained. Compared with the tridimensional array, the planar array has the advantages of less space and easy deployment; therefore, it is more widely used. In this paper, a human hand movement sensing system based on human body electrostatics was established to perform verification experiments. The results show that this method can measure the height of hand movements with good accuracy to meet the requirements of non-contact human-computer interactions.

Vertical Farming: Revolutionizing Sustainable Agriculture in the 21st Century

“…Sensors and monitoring systems are used to track key parameters such as temperature, humidity, light intensity, nutrient levels, pH, and water quality in real-time [31]. This data is used to make adjustments to the growing environment and optimize plant growth, as well as to detect and prevent problems such as nutrient deficiencies or disease outbreaks [32].…”

Remote monitoring method for human body electrostatic potential based on symbolic regression machine learning

“…The [11,12] described a non-contact and real-time measurement technique of human body potential using ultra-sensitive electrostatic induction. The [13,14] used spherical electrode arrays to locate the hand's real-time position using the human body electrostatic potential. In [15,16], Prance invented an electrostatic potential sensor (EPS) with high sensitivity, high accuracy, better stability, and low noise.…”

Indoor Localization Method of Personnel Movement Based on Non-Contact Electrostatic Potential Measurements

“…References [25,26] proposed a high-sensitivity electrostatic induction sensor that enables the recognition of human movements and individual characteristics. References [27,28] used spherical electrode arrays to measure the induced signal from the electrostatic potential of the hand and realized real-time gesture recognition. Prance invented an electrostatic potential sensor (EPS) with high input resistance (~1018 Ω), low input capacitance (~10-17 F), and low noise characteristics in the bandwidth [29].…”
