Abstract: A sensor apparatus including a flexible substrate and a wrinkled conductor disposed on the flexible substrate. In some embodiments, the conductor includes micro-scale invaginations. Also disclosed are methods of making a sensor apparatus, including: placing a mask over a polymeric sheet, wherein the mask is configured to block regions of the polymeric sheet, depositing a conductive structure on the polymeric sheet at regions exposed through the mask, shrinking the polymeric sheet with conductive structure patterned on its surface by heating, and transferring the conductive structure to a flexible substrate. Also disclosed are methods of sensing a health condition of a user or patient. The methods include coupling a sensor apparatus to a surface of a user or patient overlying structures to be monitored. The sensor apparatus may include a crumpled conductor capable of detecting strain. Strain is detected by directing current through the sensor apparatus during flexing of the surface and measuring a characteristic of the sensor apparatus based on the strain to generate an output for a user, indicative of the condition of the user or patient.

Abstract: A wearable sensor apparatus is disclosed that includes a flexible substrate adapted to be coupled with a skin surface of an expectant mother, A conductor is disposed on the flexible substrate. The conductor can include micron-scale invaginations. The conductor can be capable of repeatable variation in resistance when subject to a strain. Also disclosed is a system for monitoring the health of a fetus in utero that includes a wearable sensor apparatus. The wrearable sensor apparatus is configured to output a signal responsive to an electrical input. The system includes a computing system with one or more hardware processors. The computing system is programmed to implement a signal processing module configured to access the output, signal from the wearable strain gauge and generate an output indicative of health of the baby in utero. The output can be based in part on the received output signal and previously stored correlations between signal data from the wearable strain gauge and observations of the system or of the mother. A user interface module can be provided and can be configured to display an output indicative of health of the baby in utero.

Abstract: Soft capacitive pressure sensors for continuous wearable health monitoring applications are described herein. Wrinkled gold thin films on elastomeric substrates are used as robust parallel plate electrodes to create a robust integration with the polymer, allowing repeated normal force to deform the thin film without failure. By incorporating micro-ridged structures that support the counter electrodes to create air cavities within the elastomeric dielectric layer, pressure sensitivity is further increased. The pressure sensors are configured to measure human physiological signals such as pressure exerted from a radial pulse on a skin's surface. The radial pulse pressure detected by the sensor can be correlated to an arterial blood pressure. Calibration of said pressure sensors using a neural network allows for determination of absolute blood pressure.
