Abstract— In this paper we consider the use of tactile sensors to propose a better prosthetic hand from the given two types of artificial hands based upon the analysis of their force profiles when they are used to activate a push button of a mobile phone device. This experiment provides results which would lead to a possible adaptation of the better prosthetic hand. The results involve the stochastic analysis of the force profiles obtained from the human hand and the two prosthetic hands.
Index Terms— Dexterity, prosthetics, tactile sensors.

INTRODUCTION
Human dexterity is a vital thing: people are able to grasp various objects, differentiate between objects, perform complex tasks, and switch between various actions in response to changing environments [1]. This is possible because of the physical structure of our hand (multiple fingers with multiple degrees of freedom) and also because of our sophisticated control system which is the brain. In recent times a lot of research has been conducted to try and create an artificial sense of touch for robots to bestow them with some of the manipulation capabilities that humans have [2]. These manipulations require a control of forces and motions at the area of contact between the fingers and the environment which can only be accomplished by touch. The artificial hands for sociable robotics and prosthetics are expected to be touched by other people [3]. Because the skin is the main interface during the contact, there arises a need to duplicate humanlike characteristics for artificial skins for safety and social acceptance [4].
Tactile sensing can provide essential information about properties such as
