Abstract: This disclosure provides systems and methods for delivering a neural stimulation pulse. A neural implant device can include an energy harvesting circuit configured to receive an input signal and generate an electrical signal based on the received input signal. A diode rectifier in series with the energy harvesting circuit can rectify the electrical signal. The energy harvesting circuit and the diode rectifier can be encapsulated within a biocompatible electrically insulating material. A neural electrode can be exposed through the biocompatible electrically insulating material. The neural electrode can be configured to deliver a neural stimulation pulse. The neural implant device can have a volume that is less than about 1.0 cubic millimeter.

Abstract: Aspects are generally directed to systems and methods that integrate contactless electric field detectors to measure biophysical signals generated by a body. In one example, a biophysical sensing system includes a sensing assembly including an array of contactless electric field detectors, each of the contactless electric field detectors being configured to sense a corresponding component of an electric field generated by a body, a control system to receive sensor data indicative of the components of the electric field sensed by each of the contactless electric field detectors, the control system being configured to generate an estimate of the electric field based on the sensor data, and a feedback system coupled to at least the control system, the feedback system including at least one feedback interface, the feedback system being configured to operate the feedback interface to provide feedback based on the estimate of the electric field.

Abstract: Aspects are generally directed to a compact and low-noise electric field detector, methods of operation, and methods of production thereof. In one example, an electric field detector includes a proof mass, a source of concentrated charge coupled to the proof mass, and a substrate having a substrate offset space defined therein, the proof mass being suspended above the substrate offset space. The electric field detector further includes a sense electrode disposed on the substrate within the substrate offset space and proximate the proof mass, the sense electrode being configured to measure a change in capacitance relative to the proof mass from movement of the proof mass in response to a received electric field at the source of concentrated charge. The electric field detector includes a control circuit coupled to the sense electrode and configured to determine a characteristic of the electric field based on the measured change in capacitance.

Abstract: A chip scale encapsulated vacuum field emission device integrated circuit and method of fabrication therefor are disclosed. The vacuum field emission device is a monolithically fabricated triode vacuum field emission device, also known as a VACFET device. The VACFET device includes a substrate, a VACFET formed laterally on the substrate, and a containment shell that seals around a periphery of the VACFET and against the substrate. Preferably, the VACFET of the VACFET device includes an anode and a cathode formed on the substrate, a bottom gate and a top gate. The bottom gate is located between the anode and the cathode and the substrate, and the top gate is located above the anode and the cathode with respect to the substrate.

Abstract: Aspects are generally directed to a compact and low-noise magnetic field detector, methods of operation, and methods of production thereof. In one example, a magnetic field detector includes a proof mass, a magnetic dipole source coupled to the proof mass, and a substrate having a substrate offset space defined therein, the proof mass being suspended above the substrate offset space. The magnetic field detector further includes a sense electrode disposed on the substrate within the substrate offset space and positioned proximate the proof mass, the sense electrode being configured to measure a change in capacitance relative to the proof mass from movement of the proof mass in response to a received magnetic field at the magnetic dipole source. The magnetic field detector includes a control circuit coupled to the sense electrode and configured to determine a characteristic of the magnetic field based on the measured change in capacitance.
