Abstract

A device for eyelid treatment has a wearable object, a magnetic element, a biosignal sensor, an electromagnetic actuator, a controller, and a release button. The wearable object is wearable on a user's face and the magnetic element is to be adhered to an affected eyelid. The biosignal sensor on the wearable object detects muscle activities in a periorbital area of the user and generates sensing data. The controller activates or deactivates the electromagnetic actuator based on the sensing data. When the electromagnetic actuator is activated to attract the magnetic element, the affected eyelid is allowed to open or close. When the release button triggered, vibration sensing signal exceeds the threshold, captured image suddenly changes beyond a certain level, or pressure from thin-film pressure sensors suddenly becomes unbalanced or decreases, the magnetic attraction between the electromagnetic actuator and the magnetic element is interrupted, thus preventing injuries to the user’s eyelid.

Dependent claims

A feedback-enabled magnetic assistance device for eyelid management comprising:

a wearable object configured to be worn on a user’s face;
a magnetic element adapted to be affixed on an affected eyelid of the user;
a biosignal sensor mounted on the wearable object, detecting muscle activities in a periorbital area of the user, and producing sensing data corresponding to the muscle activities;
an electromagnetic actuator mounted on the wearable object at a position corresponding to the magnetic element, wherein the electromagnetic actuator is controllable to be activated to generate a magnetic attraction between the magnetic element and the electromagnetic actuator, or alternatively is controllable to be deactivated to interrupt the magnetic attraction;
and
a controller electrically connected to the biosignal sensor and the electromagnetic actuator via a signal wire, and configured to activate or deactivate the electromagnetic actuator according to the sensing data acquired from the biosignal sensor;
a release button electrically configured on the controller, wherein the controller deactivates the electromagnetic actuator while the release button is triggered.
