Abstract

Electronic assistive gloves for covering artificial prosthetic or robotic hands. The glove includes a base layer formed to fit on the artificial hand, a plurality of sensors carried by the base layer, and an encapsulation layer covering the base layer and formed of a material that mimics human skin.

First claim

The invention claimed is:

1. An electronic assistive glove for covering an artificial hand, the glove comprising:
a base layer formed to fit on the artificial hand;
a plurality of sensors carried by the base layer;
conductive traces carried by the base layer and interconnecting the sensors, the conductive traces comprising individual trace patterns having serpentine shapes; and
an encapsulation layer that conceals the base layer and the conductive traces, the encapsulation layer being formed of a material that mimics human skin.

2. The electronic assistive glove according to claim 1 , wherein the glove comprises a palm and fingers extending from the palm, the sensors are arranged in different sets of the sensors that are each connected by one of the individual trace patterns of the conductive traces, some of the sensors of a first set of the different sets being located in the palm and connected by a first of the individual trace patterns to others of the sensors of the first set located in one of the fingers of the glove.

3. The electronic assistive glove according to claim 1 , wherein the conductive traces are formed on the base layer, formed on the encapsulation layer, or embedded in the base or encapsulation layers.

4. The electronic assistive glove according to claim 1 , wherein the base layer defines a base glove having a wrist region, fingers, and a palm therebetween, and each of the individual trace patterns defines a path that starts adjacent the wrist region of the base glove, has an outbound portion routed to a location adjacent a tip of one of the fingers of the base glove, and an inbound portion that is routed back to form a terminus of the path at the wrist region of the base glove.

5. The electronic assistive glove according to claim 4 , wherein the start and terminus of each path defines electrical leads for a corresponding one of the individual trace patterns at the wrist region of the base glove.

6. The electronic assistive glove according to claim 4 , wherein the individual trace patterns are electrically isolated from each other by the base layer.

7. The electronic assistive glove according to claim 4 , wherein at least one of the sensors is located within a corresponding one of the individual trace patterns and bridges and is connected to the outbound and inbound portions of the corresponding individual trace pattern.

8. The electronic assistive glove according to claim 4 , wherein the base glove comprises a plurality of the sensors located within a finger portion of each of the individual trace patterns located on the fingers of the base glove.

9. The electronic assistive glove according to claim 8 , wherein the base glove comprises a plurality of the sensors located within a palm portion of each of the individual trace patterns located on the palm of the base glove.

10. The electronic assistive glove according to claim 1 , wherein the sensors comprise a plurality of pressure sensors.

11. The electronic assistive glove according to claim 1 , wherein the sensors comprise a plurality of temperature sensors.

12. The electronic assistive glove according to claim 1 , wherein the sensors comprise a plurality of hydration sensors that measure hydration levels of objects grasped by the glove.

13. The electronic assistive glove according to claim 1 , further comprising at least one heating element configured to maintain an exterior surface of the electronic assistive glove at a temperature of about 34 to about 39° C.

14. The electronic assistive glove according to claim 1 , further comprising an electronic control and display unit that receives output signals from the sensors and displays information derived from the output signals.

15. The electronic assistive glove according to claim 14 , wherein each of the individual trace patterns is connected to the electronic control and display unit.

16. The electronic assistive glove according to claim 1 , wherein the sensors are added to the base layer by transfer printing.

17. The robotic hand covered by the electronic assistive glove according to claim 16 .

18. The electronic assistive glove according to claim 1 , wherein the artificial hand is a prosthetic hand.

19. The prosthetic hand covered by the electronic assistive glove according to claim 18 .

20. The electronic assistive glove according to claim 1 , wherein the artificial hand is a robotic hand.
