    摘要: A potentiostat is an essential piece of analytical equipment for studying electrochemical devices and reactions. As the design of electrochemical devices evolve, applications for systems with multiple working electrodes have become more common. These applications drive a need for low-cost multi-channel potentiostat systems.
    Embodiments describe herein include a portable, low-cost and scalable system with a modular design that can support 8 to 64 channels at a cost as low as $8 per channel. This design can replace the functionality of commercial potentiostats which cost upwards of $10k for certain applications. Each channel in the multi-channel potentiostat has an independent adjustable voltage source with a built-in ammeter and switch, making the device flexible for various configurations. The multi-channel potentiostat can be designed for low current applications (nA range), but its purpose can change by varying its shunt resistor value. The system can either function as a standalone device or remotely controlled. We demonstrate the functionality of this system for the control of a 24-channel bioelectronic ion pump for open- and closed-loop control of pH.

    摘要: A robotic arm having one or more hybrid (soft-rigid) joints includes a first link, a second link, and a joint interconnecting the first link and the second link, such that the first link is movable relative to the second link along an axis of motion. The joint includes: a socket component coupled to a distal end portion of the second link and a ball component coupled to a proximal end portion of first link, the ball component is configured to rotationally fit within the socket component. The joint also includes a flexible membrane encasing the socket component and the ball component. The robotic arm is controllable using a reinforcement learning algorithm training using a simulation of the robotic arm and optionally, further training in a physical world.

    摘要: An alignment platform for use with an imaging device includes an outer stage, an inner stage disposed within the outer stage and flexibly coupled to the outer stage, and a central frame disposed within the inner stage and flexibly coupled to the inner stage. The central frame is configured to support an object being imaged. The inner stage and the central frame are movable relative to the outer stage along a first axis and the central frame is movable relative to outer stage and the inner stage along a second axis that is perpendicular to the first axis.
