Abstract

A biosensor feedback device for use in detecting a grip pressure and torque of a hand against a handle of a sporting implement. The device includes a flexible thin film substrate which is conformable to the handle of the sporting implement, and an array of digital pressure sensors disposed on the flexible substrate. The sensors are connected to a signal, such as a buzzer, that indicates detection of pressure or torque exceeding a desired threshold. The array of sensors can be divided into two or more sub-arrays of sensors of different sensitivities, and each of the sub-arrays can be connected to (or disconnected from) the signal as desired. The sensor-beating substrate is secured to the handle of the sporting implement by an elongated, stretchable tubular sheath. This sheath is capable of being manipulated from a first position, in which it is rolled substantially entirely onto itself to form a generally doughnut-shaped roll, to a second position in which it is unrolled over the sensor substrate to secure the substrate to the handle of the sporting implement.

Claims

1. A biosensor feedback device for use in detecting a grip pressure of a hand against a handle of a sporting implement, comprising:

electronic pressure detection means for detecting and signalling hand pressure on the sporting implement handle exceeding a predetermined level, the pressure detection means including one or more portions of sensor substrate being generally conformable to the handle and including pressure sensor means for sensing grip pressure; and

attachment means for securing the sensor substrate to the handle of the sporting implement, the attachment means including a housing and an elongated, stretchable tubular sheath rolled substantially entirely onto itself to form a generally doughnut-shaped roll on the housing, the sheath being capable of being unrolled over the sensor substrate.

2. The device of claim 1 wherein the attachment means includes a strap secured to the one or more portions of sensor substrate, the strap including fastening means for releasably securing the strap, and, hence, the adjacent portion of the sensor substrate, to the handle of the sporting implement.

3. The device of claim 1 wherein the stretchable tubular sheath is made from an elastically distensible latex rubber.

4. The device of claim 1 wherein the stretchable tubular sheath is of a thickness of about 0.01 inch to about 0.1 inch.

5. The device of claim 1 wherein the stretchable tubular sheath is of a thickness of about 0.014 inch to about 0.040 inch.

6. The device of claim 1 wherein the stretchable tubular sheath, in its relaxed state, is thicker at one end and thinner at an opposite end.

7. The device of claim 6 wherein the thickness of the stretchable tubular sheath at its thicker end is about 0.01 inch to about 0.08 inch, and the thickness at the opposite end is about 0.005 to about 0.05 inch.

8. The device of claim 6 wherein the thickness of the stretchable tubular sheath at one end is at least about 50% greater than the thickness at the opposite end.

9. The device of claim 6 wherein the thickness of the stretchable tubular sheath at one end is at least about 100% greater than the thickness at the opposite end.

10. The device of claim 1 wherein the diameter of the stretchable tubular sheath, in its relaxed state, is at least about 10% less than the diameter of the handle of the sporting implement.

11. The device of claim 10 wherein the handle of the sporting implement includes first and second portions, the first portion having a larger cross-sectional diameter than the second portion, the stretchable tubular sheath, in relaxed state, having a cross-sectional diameter that is at least about 10% less than the cross-sectional diameter of the second section of the sporting implement handle.

12. A biosensor feedback device for use in detecting a grip pressure of a hand against a handle of a sporting implement,
