This is huge, considering how simple the circuitry is.<p>Based on the prototyping process, they have gone for an expensive impedance analysis DSP chip with 0.1Hz resolution and a relatively wide frequency range. If this gets adopted by a major manufacturer, you could spin an ASIC for pocket change at the optimal frequency (40KHz empirically derived by researchers). Additionally, put the multiplexer on the same chip and make a single chip solution.<p>The paper is focused more on the machine learning aspect but there are obvious points to improve on the electrical bits!<p>I&#x27;ll be waiting until this appears as a Myo-like form factors for hackers to play with.
