reduced graphene oxide tattoo as wearable Proximity Sensor
arXiv: Human-Computer Interaction, 2020Co-Authors: Vaishakh Kedambaimoole, Neelotpala Kumar, Vijay Shirhatti, Suresh Nuthalapati, Saurabh Kumar, M M Nayak, Prosenjit Sen, Deji Akinwande, K RajannaAbstract:The human body is punctuated with wide array of Sensory systems that provide a high evolutionary advantage by facilitating formation of a detailed picture of the immediate surroundings. The Sensors range across a wide spectrum, acquiring input from non-contact audio-visual means to contact based input via pressure and temperature. The ambit of sensing can be extended further by imparting the body with increased non-contact sensing capability through the phenomenon of electrostatics. Here we present graphene-based tattoo Sensor for Proximity sensing, employing the principle of electrostatic gating. The Sensor shows a remarkable change in resistance upon exposure to objects surrounded with static charge on them. Compared to prior work in this field, the Sensor has demonstrated the highest recorded Proximity detection range of 20 cm. It is ultra-thin, highly skin conformal and comes with a facile transfer process such that it can be tattooed on highly curvilinear rough substrates like the human skin, unlike other graphene-based Proximity Sensors reported before. Present work details the operation of wearable Proximity Sensor while exploring the effect of mounting body on the working mechanism. A possible role of the Sensor as an alerting system against unwarranted contact with objects in public places especially during the current SARS-CoV-2 pandemic has also been explored in the form of an LED bracelet whose color is controlled by the Proximity Sensor attached to it.

net structure Proximity Sensor high speed and free form Sensor with analog computing circuit
IEEE-ASME Transactions on Mechatronics, 2015Co-Authors: Hiroaki Hasegawa, Yosuke Suzuki, Aiguo Ming, Keisuke Koyama, Masatoshi Ishikawa, Makoto ShimojoAbstract:This paper proposes a Proximity sensing system, which has advantages of wide sensing area and rapid response. For the rapid and safe behavior of robots, high-speed detection of nearby and noncontact objects is important because of shorter time-to-contact. Here, we propose net-structure Proximity Sensor (NSPS), which covers large sensing area and fulfills 1-ms response time. NSPS is an array of infrared reflective Proximity Sensor elements integrated by a resistor network circuitry. Executing analog computation on the electrical circuitry, the sensing system outputs a few of meaningful signals, from the reaction distribution of all the elements. The signals mean the center position and approximate distance to the object. This Sensor requires only six external wires regardless of the number of detecting elements. In this paper, we first show that various sizes of NSPS are easily configured by only using standard electronic parts. Next, we prototype NSPS with 25 elements in $5 \times 5$ matrix, and verify the output characteristics by experiments. At last, we discuss the availability of NSPS for robot hand systems and human–machine interface systems.

robust robotic grasping using ir net structure Proximity Sensor to handle objects with unknown position and attitude
International Conference on Robotics and Automation, 2013Co-Authors: Kenji Suzuki, Yosuke Suzuki, Masatoshi Ishikawa, Makoto ShimojoAbstract:In this paper, we focus on unknown parameters such as the position and attitude of the object, and describe a short-range, high-speed and noncontact sensing method for obtaining the position and attitude of the object using IR Net-Structure Proximity Sensor (“IR-NSPS”) which complements the dead region of Sensory information between visual and tactile sensing. To be more precise, we propose two effective control methods which are pre-shaping and object positioning using IR-NSPS for robust grasping by adjusting the gripper configuration in response to attitude error of up to ±45 deg and the position error of up to ±80 mm of the unknown object. The methods therefore can significantly increase the speed and effectiveness of grasping objects without requiring a specific approach that depends on a vision Sensor. Furthermore, to demonstrate the advantages of pre-shaping and object positioning, object grasping experiments were performed using these two operations to grasp objects placed randomly on a tabletop.
