  • Portable instrument for field ready electrochemical experimentation
    Patent number: 11536691
    Abstract: A low-cost, portable potentiostat capable of performing several different electrochemical experiments (e.g. cyclic voltammetry and anodic stripping voltammetry) was designed. The potentiostat runs on one or more batteries and has a battery life of over two weeks. Further, the potentiostat of the present invention is capable of self-calibrating and has a linear dynamic range spanning several orders of magnitude. It is also capable of saving data onto an onboard data storage card and is able to export the data to a computer for additional analysis. The potentiostat requires no peripheral hardware and is suitable for use by those with even minimal training in electrochemistry.

  • Collection and processing of analytical data
    Patent number: 10908172
    Abstract: A self-contained hardware platform can be used for the instruction of analog signal processing techniques. An exemplary hardware platform includes a bit depth module, a noise generation module, a signal filter module, and a lock-in amplifier module. In this way, the hardware platform is capable of performing experiments for the instruction of noise source elucidation, Nyquist sampling and resolution, analog filtering, and/or lock-in amplification, among others.
