Wearable Sensor Arrays for Detailed Sweat Profiles

Wearable technologies can play a significant role in realizing personalized medicine through continuously monitoring an individual’s physical and physiological states. Most currently developed wearable technologies are capable only in tracking the physical activities of an individual and fail to provide insight into the individual’s state of health. Human sweat contains the physiologically rich information needed to infer an individual’s sate of health and is an excellent candidate for non-invasive monitoring. The wearable sweat sensors can serve as an ideal platform for a wide range of real-time healthcare monitoring such as exercise-induced dehydration and medical diagnosis.

Monolithic 3D Printing of Smart Objects

The number of interconnected sensors and actuators are expected to grow beyond thousands of units per person by 2020, and new manufacturing processes will be required for personalization and seamless integration of such devices into our surrounding objects. One major general challenge for manufacturers is with scaling production of mechanically sophisticated and tailored objects while maintaining or improving efficiency. 3D printing may be an excellent candidate for manufacturing at scale as it enables on-demand and rapid manufacturing of user-defined objects. However, traditional 3D approaches have a unique set of challenges due to incompatible processing approaches with metals with plastics. To address these challenges, researchers at UC Berkeley have developed novel 3D printing techniques for fully-integrated smart objects that embed liquid metal-based passive/active components and silicon integrated circuits to achieve greater system-level functionalities. For demonstration, UC researchers created a form-fitting glove with embedded programmable heater, temperature sensor, and the associated control electronics for thermotherapeutic treatment, specifically tailored to an individual’s body. These novel processes can enable assembly of electronic components into complex 3D architectures, which may provide a new platform for creating personalized smart objects in volume.

Monolithic Integration of Ultra-Scaled High Performance Pin-Size Wearable Electronics

Wearable electronics for health monitoring have gained increased interest after conformal tattoo-like electronic sensors were co-integrated on elastomeric sheets.  One of the design requirements in such wearable electronics was to carefully adjust the effective Young’s modulus and bending stiffness of the resulting layered electronics, and this has restrained the compact integration of the electronic components because the single transistor elements had dimensions that were in millimeter scale. The promise of tattoo-like epidermal electronics has inspired a significant research effort to optimize the mechanics of these structures.

Flexible Penetrating Cortical Multielectrode Array and Manufacturing Methods Thereof

Signals from neuronal ensembles may be collected from cortical tissue using various multi-electrode array (MEA) designs. To achieve 3D mapping of the brain, scientists have developed penetrating electrodes such as the Michigan and Utah electrodes, however, these large nonflexible electrodes are known to elicit a reactive tissue response in cortical tissue. And while the Michigan and Utah electrodes were successfully used in clinical trials; these devices poorly conform to cortical tissue. Alternatively, conformable bio-integrated electronics have been developed using ultrathin films, but the current devices lack sufficient spatial density to achieve 3D mapping of the cortical tissue.
