Abstract: Eyewear exhibiting a variable light transmittance functionality is achieved by including a smart lens incorporating an electrochromic (EC) polymer, switchable between a first state and a second state in response to a voltage selectively applied thereto. The smart eyewear includes the smart lens, a voltage source, and a support. The EC polymer transmits more light in the first state than in the second state, because changing the state of the EC polymer varies the light transmittance of the smart lens. The voltage source is configured to provide the voltage required to switch the EC polymer between the first state and the second state, while the support member is configured to support the smart lens and enable a user to wear the smart eyewear. Embodiments can include sensors and controllers to automate the switching, as well as energy harvesting elements to increase battery life.

Abstract: An electroactive polymer is used to produce a tactile sensor. The electroactive polymer (EAP) includes a sheet of an ion-exchange membrane having opposite surfaces on which are plated gold electrodes. The EAP is formed to have a dome-shape with a plurality of sensing electrodes circumferentially disposed around an outer surface of the dome. A flexible polymer underlying the EAP supports it and prevents a force applied to the tactile sensor from inverting the dome. The sensor electrodes produce separate output signals indicative of different vector components of an applied force acting on the tactile sensor, so that a direction of the force can be determined. Vias provided in the electrodes are electrically coupled to a flexible circuit that conveys the output signals externally from the sensing electrodes for use and further processing. A plurality of the tactile sensors can be formed as an array on an ion-exchange membrane.

Abstract: Large contrast ratio and rapid switching laminated electrochromic (EC) polymer device includes transparent electrode, cathodic EC polymer, gel electrolyte, and counter-electrode. Preferably the cathodic EC polymer is a poly(3,4-propylenedioxythiophene) derivative, PProDOT-Me2. Counter-electrode is a conductive coating deposited on transparent substrate, with preferred coatings including gold and highly conductive carbon. Lithography and sputtering can be employed to pattern a gold layer, while screen printing can be employed to similarly pattern graphite. Empirical studies of preferred device indicate a color change of high contrast ratio of transmittance (>50% T) is rapidly (0.5-1 s) obtained upon applied 2.5 V, repeatable to at least 10,000 times, as estimated by electrochemistry. Dual layer EC devices including PProDOT-Me2 are also disclosed, as are methods for synthesizing preferred EC polymers. Preferred synthesis method for obtaining PProDOT-Me2 involves refluxing reagents in toluene in the presence of catalyst, while continually removing methanol byproduct from refluxing solution.
