Abstract: A self-powered 'near field' lithographic system 100 includes three primary components, namely, a thin film or emitter substrate 110 including a radioactive material (e.g., a radioisotope 112), a target substrate 120 which carries an energy-modifiable layer 122 (e.g., photo-resist) and a stencil (e.g., 130) that is either positioned between the emitter and target substrates fabricated upon and defined in the emitter substrate. The stencil is made from a material capable of blocking particles emitted through radioactive decay from the radioisotope of the emitter substrate. The stencil includes openings or vias 132 patterned to permit selective transmission of the particles emitted through radioactive decay from the radioisotope of the emitter substrate 110, and the stencil is preferably placed up against (or very close to) the target substrate 120.

Abstract: A self-powered sensor (e.g., 100, 180, 220, 400) can wake-up systems requiring a trigger signal to wake-up circuits or systems in power-sleep mode, conserving the battery power for emergency computations and communications. In a humidity sensor embodiment 100, radioisotope generated voltage biases are employed to power sensor capacitors to realize self-powered sensors. A first self-powered capacitor biasing architecture 160 is based on changes in the leakage resistance of the polymer capacitor 110, and a second self-powered capacitor biasing architecture 140 uses changes in the capacitance of the polymer capacitor. Another sensor embodiment uses changes in the capacitance or leakage resistance of the sensor capacitor to modulate conductance of a MOSFET 114, realizing an easily readable electronic output signal. A temperature sensor embodiment 180 and a MEMS cantilever structure based fissile material proximity sensor embodiment 400 are also disclosed.

Abstract: A signal source for use as a frequency source or time keeping signal source includes a radioactive emission source generating a substantially periodic signal corresponding to a radioactive material's disintegration rate. A radioactive emission detector generates a radioactive emission detection signal and, to stabilize the detected periodic signal, a dead time controlling attenuator blanks or shuts off the radioactive emission detection signal for a selected dead time interval in response to each detected radioactive emission (i.e., a detected signal pulse or signal component) generated by the source. The dead time controlling attenuator output provides a long-term and short-term a stable periodic signal.

Abstract: An autonomous, self -powered device includes a radioisotope-powered current impulse generator including a spring assembly comprising a cantilever, and a piezoelectric- surface acoustic wave (P-SAW) structure connected in parallel to the current impulse generator. Positive charges are accumulated on an electrically isolated 63Ni thin film due to the continuous emission of ß-particles (electrons), which are collected on the cantilever. The accumulated charge eventually pulls the cantilever into the radioisotope thin-film until electrical discharge occurs. The electrical discharge generates a transient magnetic and electrical field that can excite the RF modes of a cavity in which the electrical discharge occurs. A piezoelectric-SAW resonator is connected to the discharge assembly to control the RF frequency output. A method for generating a tuned RF signal includes inputting an energy pulse to a P-SAWresonator, exciting the resonant frequency thereof, and outputting an RF signal having a frequency tuned to the resonator frequency.

Abstract: An ultrasonic or acoustic viscosity sensor or viscometer is provided that can be used to accurately measure viscosity for fluid samples of less than 1 µl in volume. Methods for measuring viscosity for fluid samples of less than 1 µl in volume are also provided. The viscosity sensor and methods based thereon enable simultaneous measurement of bulk and dynamic (shear-rate dependent) viscosity of a non-Newtonian fluid. Bulk and dynamic viscosity of the non-Newtonian fluid can be measured simultaneously without separating constituents of the fluid, and thus distinguishing the effect of constituents on the viscosity. Dynamic viscosity of the non-Newtonian fluid can be estimated at varying shear rates, to study the deformability of the constituents of the fluid as a function of shear rate.
