Title: Oliver Hart: Innovator in Shape Memory Alloy Technology

Introduction

Oliver Hart is a distinguished inventor based in Cambridge, GB. He holds a total of nine patents, showcasing his innovative contributions to technology, particularly in the field of shape memory alloys. His work has significantly impacted various applications, including camera assemblies and actuator systems.

Latest Patents

One of Hart's latest patents is a shape memory alloy actuator designed for camera assemblies. This actuator comprises a support structure that supports an electronic component, which is susceptible to interference from magnetic flux. The actuator features a moveable part that can move relative to the support structure, with one or more shape memory alloy components connected between them. These components are configured to drive the movement of the movable part upon contraction. The design includes a first and second electrical path that extend adjacently and in parallel, allowing electrical current to flow in opposite directions to minimize combined magnetic flux interference.

Another notable patent is an actuator assembly that includes a support structure with a first friction surface and a movable part with a second friction surface. The assembly utilizes one or more shape memory alloy wires that, upon contraction, move the movable part relative to the support structure. A biasing arrangement ensures that the friction surfaces maintain a constant normal force, generating a static frictional force that constrains the movement of the movable part when the SMA wires are not contracted.
