The Dickey group is studying new ways to pattern, actuate, and control soft materials (gels, polymers, liquid metals). A common theme of our projects is the importance of thin films, interfacial phenomena, and microfabrication. One interesting application of our work is for “blue energy”; that is, harvesting energy from the motion of waves and water for clean energy sources.


Harvesting energy from the environment.

We propose to acquire the LPKF ProtoLaser R4, a class 1, pico-second laser specially designed for cutting, fabricating, and patterning a wide range of materials that will be of critical use for advanced manufacturing. Features as small as 20 microns can be easily developed using this machine and it can be used to directly process a wide range of materials for energy, biomedical systems, soft materials, inorganics, and electronics applications.

The proposed research aims to develop a fundamental understanding and control of organic vapor deposition on flat and porous surfaces. Specifically, it targets depositing low surface energy coatings on polymer films and nonwovens using a novel process technique called molecular layer deposition (MLD).

This projects focuses on efforts towards commercialization of a flexible thermoelectric module manufacturing process developed with prior funding from National Science Foundation through Advanced Self-Powered Sensors and Integrated Technologies (ASSIST) Engineering Research Center. These modules can harvest body heat and the generated electricity can be used to power wearable electronics providing the ability to perform long-term continuous sensing. A process compatible with roll-to-roll manufacturing is described. The proposal addresses potential failure mechanisms that may have an impact on the long-term reliability of the modules.

Lower limb amputees rely on prosthetic sockets as the interface with their prosthetic legs. The prosthetic sockets only work well if they fit residual limbs of amputees perfectly. Unfitted sockets cause various health issues for lower limb amputees and could significantly limit amputees’ functionality. Currently, prosthetists lack the capability to diagnose socket fit during the socket fitting procedure, which limits their capability to customize the sockets for better fit. The proposed Enable system will be used as a diagnosis tool for prosthetists. Based on a novel material, which changes color based on loaded pressure, this Enable system will permit prosthetists to evaluate the socket fit by observing the pressure distribution on the residual limb directly. During the proposed project, we will develop the smart liner system and test it through both bench tests and human subject tests. We will also validate that prosthetists will be able to use the smart liner to make appropriate socket fit diagnosis through simulated clinical cases.

This proposal focuses on a way to self-power devices by converting mechanical energy into electricity. The approach will use all soft materials and can convert electricity via all modes of deformation.

Thermal control in engineered systems is typically accomplished using fixed heat flow paths and by varying the amount of heat (energy flow) provided in order to control temperature at specified point(s) within the system. The goal of this work is to develop a practical device that allows heat flow paths to be adjusted dynamically via more advanced thermal control logic and tuned thermal interfaces.

The goal of this new project is to study and explore a new material whose dielectric constant decreases with deformation. Consequently, it can change geometry due to mechanical deformation without changing capacitance. Future electronic devices are envisioned to be mechanically compliant (flexible, soft, stretchable) to facilitate human-machine interactions and new types of wearable devices. Such devices can change geometry and thus capacitance in response to deformation. Although these changes can be useful for sensing, in other applications changes in capacitance are undesirable. To offset such changes, we propose a new dielectric material that can change dielectric properties in response to deformation.
