Tactile sensors are essential if robots are to safely interact with the external world and to dexterously manipulate objects. Current tactile sensors have limitations restricting their use, notably being too fragile or having limited performance. Magnetic field-based soft tactile sensors offer a potential improvement, being durable, low cost, accurate and high bandwidth, but they are relatively...

Grasping and manipulation of objects, as well as the capability interacting safely with the environment (possibly including also humans), is a fundamental task for a humanoid robot. In order to tackle these issues a great effort has been put for over two decades to develop robot hands or mechanisms emulating the grasping capabilities of a human hand (Salisbury & Mason 1985; Jacobsen et al. 1986...

The major requirement of implantable biomedical equipment like pacemaker, hearing aid device must have low power consumption and reliability. In order to provide a power to this biomedical equipment’s a new approach is presented in this paper, to extract electric power from heat of the subject or human body. Hereby the surgeries for battery implantation in the subject or human body can be avoid...

In this paper, we introduce a new touch sensor design, which we refer to as hybrid tactile sensor. It combines the simplicity of analog touch sensing, which is widely used in electronic touch screens and touchpads, with the ability of shape discrimination of the array touch senstactile sensors designed for robotics applidescribe the construction techniques of the sensor, its modelling, and shap...

This paper describes a tactile sensor design, allowing data acquisition from a sensor array using a single wire. The sensor is implemented as a filter. Sensor excitation changes filter characteristics, and the pressure profile can be recovered from the filter’s impulse response. The method is also applicable to sensor arrays for other scalar fields than pressure, such as heat, proximity, or rad...

Imitating the human skin structure, an arrayed type tactile sensor composed of many force sensing elements distributed on four stories is proposed. The information processing method for this sensor using neural network (NN) and Support Vector Machine (SVM) is investigated. Since a practical sensor is under development, the finite element method (FEM) simulation is employed to simulate the data ...
