What is a capacitive switch?
A capacitive switch is a type of switch that operates by touch. It works with a finger touch, like a smartphone screen or touchpad. There are no physical buttons, and the device responds simply by bringing your finger close to it.
Please try to imagine. Let's say you're in a cafe and the table surface is a touchscreen. Tap your finger on a specific spot on the table to order your coffee. This is the basic principle of capacitive switches. Although you can't see the physical buttons, you can tap them to respond and place your order. Let's consider an example of home use. Suppose the light switch mounted on the wall is a capacitive switch. This switch turns the light on and off just by touching the surface. Unlike traditional push-button switches, it looks stylish and has a flat surface, giving it an excellent design. It's also easy to clean and doesn't collect dust because there are no physical buttons.
Capacitive switches thus bring many conveniences in daily life and at the same time can increase design freedom. This time, we will introduce an example of applying a capacitive switch to a remote control used at home.
Can you make a remote control (switch) like this?
・Stylish and cool! A remote control (switch) with an elaborate design
・Embedded remote control (switch) that can withstand water exposure
・Original remote control (switch), etc.
Mr. K from Macnica recently completely renovated his house and is very satisfied with his favorite design of the room and furniture, but Mr. K, who is particular about the details, also wants to make the remote control (switch) that he uses frequently on a daily basis stylish and smart! That's what I thought. Therefore, I would like to talk about the ``fashionable remote control (switch)'' that Mr. K experimented with and made.
Conventional remote controls (switches) usually come in colors such as black, white, or silver, and the switch is attached to a case made of a familiar material or shape, but first of all, I wanted to change its appearance. To make such a remote control (switch)...
By combining the "infrared learning remote control" and the "electrostatic touch sheet," you can attach a cover made of various materials to the electrostatic touch sheet, and you can operate the learning remote control by touching the top of the cover. becomes possible. By applying this technology, electrostatic touch sheets can be embedded under various materials, making it possible to create unique remote controls (switches).
Mr. K wanted to make a smart remote control (switch) that would match the interior of his home, but what were the results of his experiment?
Greater flexibility in materials and designs!
■ What you can do with the "electrostatic touch sheet" + "learning type infrared remote control" that Mr. K used this time
・It is possible to control various home appliances and digital devices such as "TV", "fan", "DVD player" which are usually controlled by remote control.
・Material-free: Touch switches can be made of various materials such as gypsum board, glass, marble, and wood.
・Embedded remote control can be realized in various places
・Electrostatic sensitivity can be adjusted according to the material
1. I made a "marble" remote control. Check out the video of the experiment! Gorgeous (0'44")
2. I made a "transparent acrylic" remote control. Check out the video of the experiment! Fashionable (0'27")
3. I made a "wood" remote control. Check out the video of the experiment! Japanese Style (0'42")
Use your own ideas to turn curved surfaces into touch remote controls!
By using a capacitive touch sensor sheet, it is also possible to "support curved surfaces" with a flexible substrate!
The picture below is an example of a "curved surface compatible remote control". By pasting an electrostatic touch sheet along the curved surface (inner surface) of a PET bottle, a "curved remote control" that touches the surface of the PET bottle was created! In other words, if you embed an electrostatic touch sheet in various things, you can transform it into a completely new and unique touch remote control!
4. I made a "curved surface" remote control. Check out the video of the experiment! I've never seen a remote like this before (1'09")
Would you like to create new value with free ideas?
Mr. K introduced how to make a remote control that is particular about design. What do you think?
This time, we introduced that by applying an ultra-thin and flexible capacitive touch sensor, it is possible to create switches with various ideas regardless of materials and curved surfaces. In order to realize the idea of "I want to make this kind of thing", it is possible to create products with new value by combining "manufacturing know-how" with "devising materials and parts" like this time.
