Pressure sensor pads are electronic devices that capture physical force contact to generate some sort of a response. There is a truly endless amount of applications for pressure sensor pads, ranging from an input mechanism in a human-machine interface (HMI), a method to capture intruders in a force-sensitive security system, and beyond.

Whether developed as a single-point sensing device, or as an array of multiple pressure-sensing elements, pressure sensor pads can be created to perform many different types of functions, including:

Detecting and measuring relative change in force or applied load

Detecting and measuring the rate of changes in an applied load

Identifying force thresholds to trigger an appropriate reaction

Detecting contact and/or touch

How Are Pressure Sensor Pads Constructed?

Most pressure sensor pads are typically created with four source components:

A force sensor (or pressure sensor)

Load cells, strain gauges, microelectromechanical systems (MEMs), and force-sensitive resistors (FSRs)

1. Interface circuit (aka, breadboard or microcontroller)

2. A method to capture or display feedback from the pressure sensor pad

3. A power supply

Certainly, these elements get more complex depending on the needs of the application. Interface materials or protective covers may also be required, depending on the operating environment.

In this article, we will show you how to create a simple, single-point pressure sensor pad, using an ultra-thin force sensor.

Here's What We're Working With

Step 1: Connecting the Pressure Sensor Pad Components

First, insert the two leads of the force sensor into the connecting points of the interface electronics, and then connect the 9V battery to the battery clip. Most interface electronic boards include a small light that will light up when the power supply is successfully connected.

Next, connect the Black and Red clips from the multimeter to the connecting wires of the interface circuit board. The Black probe should be clipped to the wire that is labeled "ground" or "GND."

Once everything is connected, turn on your multimeter. For the purpose of this exercise, we'll be setting the multimeter dial to Direct Current Voltage (DC voltage). This setting allows you to capture raw force readings. Press down on your sensor to test the connections, and monitor feedback on the multimeter.

Note: This point of the process is a good time to try testing different interface materials on your force sensor. For instance, if you plan to embed this sensor into a handheld device - e.g., a remote controller - you determine what materials will provide the best results from a sensitivity perspective.

Step 2: Adjusting the Pressure Sensor Pad Sensitivity

No matter what you plan for your pressure sensor pad application, it's always ideal to select an interface circuit that includes adjustable components. The FlexiForce Quickstart Board we're using in this example includes an adjustable potentiometer that allows the user to adjust the sensitivity of their sensor. This article explains how FlexiForce users can get the most of their sensor performance with the ability to adjust force ranges.

To adjust sensitivity, use a small screwdriver to either tighten or loosen the potentiometer (a small, blue unit with a screw).

Turning to the left will increase sensitivity (requiring less force to produce a response), while turning to the right decreases sensitivity (requiring more force to produce a response).

Your Pressure Sensor Pad is Now Complete!

This is just one way you can make a simple, low-cost pressure sensor pad. There are several different kinds of interface electronics (e.g., Arduino microcontrollers, breadboards, etc.) or methods to convert the raw analog force signal into a digital response.

If you determine FlexiForce sensors may be a good fit for your pressure sensor pad device, the FlexiForce OEM Development Kit is a great way to obtain proof-of-concept data, without having to make a significant upfront investment.

Limerick Wave Ltd have developed a mechanical power take off (PTO) mechanism that converts the motion of the waves to electrical power.

Wave Energy Converter (WEC)

The Limerick Wave PTO technology is suited to any WEC device that captures the two way motion of the waves. This two way motion is mechanically converted into one direction to drive an electrical generator that along with the PTO is protected from the harsh environment of the sea.

The PTO technology is designed to harness energy from the ocean. It can either be moored to the seabed or positioned above the water.

The PTO mechanism devised by Limerick Wave uses a combination of existing technologies that include a gearbox and a flywheel. This arrangement eliminates the problems experienced through the use of hydraulic oil, as the only oil used in this array is used in the gearbox to prevent the gears from sticking or overheating. According to HMRC (2011) the flywheel produces smooth energy, with an output standard deviation output of 15% (maximum) from a 60% (maximum) input standard deviation and a maximum efficiency of 74%. Over travel is something that most WEC experience difficulties with, this not an issue for Limerick Wave's power take off unit as the device was designed to rotate 360° with no end stop required, ensuring limited damage to the PTO system during rough seas.

The DOI Foundation is a not-for-profit organization. We govern the Digital Object Identifier (DOI) system on behalf of the agencies who manage DOI registries and provide services to their respective communities. We are the registration authority for the ISO standard (ISO 26324) for the DOI system and we are governed by our Registration Agencies.

WHAT IS THE DIGITAL OBJECT IDENTIFIER (DOI)?

A DOI name is a digital identifier of an object, any object - physical, digital, or abstract. DOIs solve a common problem: keeping track of things. Things can be matter, material, content, or activities.

Designed to be used by humans as well as machines, DOIs identify objects persistently. They allow things to be uniquely identified and accessed reliably. You know what you have, where it is, and others can track it too.

Read more about the identifier, its benefits, and how it's used

ANNOUNCING OUR NEWEST REGISTRATION AGENCY

Human & Digital (HAND) was recently appointed as the 12th Registration Agency of the DOI Foundation, assigning DOI names to legal entity humans, licensed virtual humans, and fictional characters involved in the performing arts and sports. The talent industry is becoming more connected, complex, and digitized. Managing this complexity in a programmatic way is only possible with verifiable, persistent identity of talent, both human and digital. And this is exactly what HAND provides.

Try resolving a DOI name

Type or paste a known DOI name exactly-including its prefix and suffix-into the text box below and then 'submit' to resolve it.

DOIs include a prefix (prefixes always start with 10.) and a suffix, separated by a forward slash (/). Prefacing the DOI with doi.org/ will turn it into an actionable link, for example, https://doi.org/10.47366/sabia.v5n1a3. Clicking that link will 'resolve' it, i.e. redirect to the latest information about the object it identifies, even if the object changes or moves.

Vibrational motion caused by a moving vehicle is transduced into electrical energy by a vibrational-to-electric energy converter, and stored in an electrical energy storage device such as a rechargeable battery. The electrical energy storage device may then power one or more electronic components located on the moving vehicle.
