How do we communicate with our electronic devices? There are many different 'human-machine interfaces (HMI)' options, ranging from the well-established (keyboard/mouse/mechanical switches) to somewhat more recent developments such as the capacitive touch screens found on smartphones. As greater numbers of devices around us gain 'smart' functionality, the ability to incorporate HMI components elegantly and cost-effectively is increasingly important.

Commercial interest in silicon anodes and investments into start-up companies has continued through 2021 - IDTechEx estimates that $1.9B of funding has now made its way into silicon anode start-ups. Beyond investments, there has also been greater activity regarding companies beginning to license technologies, enter into supply relationships or commercialize technologies in early adopter markets, highlighting that the promise of silicon anode technology may soon be realized.
