Providing electrical power is essential for nearly all interactive technologies, yet it often remains an afterthought. Some designs handwave altogether as "exercise later." Others hastily string together batteries to meet the system's requirements, enclosing them in whatever box fits. Vim a new approach – elevates first-class design element; frees from being series of discrete elements, instead catering exact requirements; enables take on new, flexible forms; fabricated using low-cost, accessible materials and technologies; finally, advances sustainability by rechargeable, non-toxic, edible, compostable. Vims are decomposable battery alternatives that rapidly charge can small applications hours. We present Vims, detail their characteristics, offer guidelines fabrication, explore use spanning prototyping, fashion, food, including novel systems entirely edible.
