TactileGlove - Hand Pressure and Force Measurement

The PPS TactileGloves are tactile pressure sensor gloves with embedded sensing elements throughout the palm and fingers, allowing for natural and accurate testing of pressures applied to and exerted by the hand. Nearly any hand operation can be measured accurately through the 65 individual highly sensitive sensing elements within each glove.

Our TactileGloves are wireless and battery powered. This is the only glove sensor on the market that both allows for full range of motion and creates an organic testing environment. High-resolution pressure sensing and mapping enables you to research hand movements when performing various tasks, and analyze comfort, and ergonomics through visual feedback of hand interactions.

Sensor Glove Features:

  • Ensure a natural test environment with the only glove hand sensor on the market

  • User friendly, comfortable to wear and no adhesives or wires to get in your way

  • High-resolution, sensitive sensors detect even the lowest pressures (0.1oz/3g)

  • Meant to handle the real world. It's wireless and battery powered.

  • Delivered in pairs (Left + Right). Available glove size: small, medium, and large. See: sizing chart

Product Description

The TactileGlove provides a sharp improvement in sensor measurement involving human hand and finger movements. Both simple and complex hand operations can be measured accurately and dynamically through multiple high-resolution small sensor arrays. Sixty-five sensor elements across the hand, fingers, and palm, embedded within a wireless glove allows for reliable and repeatable pressure distribution measurement.

High-resolution pressure sensing and hand mapping has versatile applications. It enables you to research and develop human movements, comfort, and ergonomics through visual feedback of hand interactions. The accompanying Chameleon Software captures and records live data to provide both numeric and image representation of pressures on the hand.


Applications

Understand and optimize worker exertion while performing hand actions. Measure force and exertion required to cutting metal with shears, strip wire, perform fine assembly tasks, and more. Understand points of high exertion within your process, and optimize your labor force to reduce potential injury.

Manufacturing Safety & Workers’ Comp Assessment:

  • Understanding work activities to prevent injury

  • Measure & visualize human grip force required to use power tools

  • Analyze grip force required for fine motor activities such as using dental tools

  • Determine if a tool modification reduces effort required

  • Quantify hand strength for return-to-work assessments

Product Ergonomic Design:

  • Quantify what forces people use naturally

  • Determine upper and lower limits of forces generated by the hand

  • Quantify effort to use tools for human factors & ergonomic designs

  • Correlate “feel” of a product in response to controlled design changes

  • Understand hand interactions with competitive products

Frequently Asked Questions

1. What is the minimum force sensitivity and mass that the TactileGlove can detect?

The minimum force that each individual force sensing glove fingertip element (38 mm²) can detect is 0.04 N.

2. Is the TactileGlove waterproof?

No, the TactileGlove is not waterproof. However, a custom skin can be added at extra cost.

3. Does the TactileGlove stretch to accommodate variations in hand size and shape?

The four glove sizes are carefully designed to cover natural hand sizes across a broad spectrum. Please choose the correct size based on your hand dimensions.

4. Does the TactileGlove measure pressure or force?

The TactileGlove is calibrated in units of pressure (i.e., psi or N/cm²). Force values are calculated using the known area of each sensor element.

5. Can the TactileGlove detect fast impact loads?

We do not recommend using the TactileGlove for impact applications.

6. How often does the TactileGlove require calibration?

The capacitive based sensing modality of PPS sensors results in an extremely stable sensor with superior reliability and repeatability. With proper use and care, the TactileGlove should retain its calibration for years.
