In this investigation, a novel indenter platform is presented and its performance evaluated for the purposes of residual-limb tissue characterization. The indenter comprised 14 position- and force-controllable actuators that circumferentially surround a biological residuum to form an actuator ring. Each indenter actuator was individually controllable in position (97.1 μm accuracy) and force (330 mN accuracy) at a PC controller feedback rate of 500 Hz, allowing for a range of measurement across a residual stump. Data were collected from 162 sensors over an EtherCAT field bus to characterize the mechanical hyperviscoelastic tissue response of two transtibial residual-limbs from a study participant with bilateral amputations. At five distinct anatomical locations across the residual-limb, force versus deflection data-including hyperviscoelastic tissue properties-are presented, demonstrating the accuracy and versatility of the multi-indenter platform for residual-limb tissue characterization.

INTRODUCTION Characterization of hyperviscoelastic tissue properties is of critical importance to the design of wearable devices that mechanically interface to the human body and exert forces on it [1]–[4]. A biological indenter is a measurement device that is used to mechanically deform biological tissue in order to measure its hyperviscoelastic properties [2]. Indenter data, and biomechanical models derived from these data, may provide critical insights into the design of apparel, shoes, prostheses, orthoses and body exoskeletons where safe and comfortable mechanical loading needs to be applied from the synthetic product to the human body [3]. While the topic of biomechanical measurement through indentation has seen increasing research focus throughout the last two decades [3], [5], indenter design deficiencies still remain. Firstly, biological indenters must be able to collect data that are accurate and repeatable in both position and force. Secondly, the indentation mechanism must be both position and force controllable in order to generate the necessary data required for the identification and evaluation of biomechanical models of tissue. Based on the review of Picard et al. (2000), we evaluate the state of the art of research in the area of in vivo biomechanical indentation of human tissue in two categories: passive and active [6], [7].
