Our previous IoT based prosthetic arm prototype used servo motors to control finger movement through an Arduino Mega, which is connected to the muscle, pulse, and temperature sensors. The Arduino Mega was also connected to a Raspberry Pi 3 model B to transfer data from/to an online web application. One major limitation encountered during testing this prosthetic device was the space occupied by these components, which makes the device bulky. In addition, these servo motors cannot control the movement of the prosthetic device precisely. In this paper, we propose to improve on the existing prosthetic limb prototype by transitioning the …

Back and neck pain are commonly associated with intervertebral disc (IVD) degeneration. Structural augmentation of diseased nucleus pulposus (NP) tissue with biomaterials could restore degeneration-related IVD height loss and degraded biomechanical behaviors; however, effective NP replacement biomaterials are not commercially available. This study developed a novel, crosslinked, dual-polymer network (DPN) hydrogel comprised of methacrylated carboxymethylcellulose (CMC) and methylcellulose (MC), and used in vitro, in situ and in vivo testing to assess its efficacy as an injectable, in situ gelling, biocompatible material that matches native NP properties and restores IVD biomechanical behaviors. Thermogelling MC was required to enable consistent and timely …
